Dana Gardner: Hi, this is Dana Gardner, Principal Analyst at Interarbor Solutions, and you're listening to BriefingsDirect.

Gardner
Our latest podcast discussion centers on how a leading Australian IT services provider, Thomas Duryea Consulting, has made a successful journey to cloud computing.

We'll learn how a cloud-of-clouds approach provides new IT services for Thomas Duryea's many Asia-Pacific region customers. Our discussion today continues a three-part series on how Thomas Duryea, or TD, designed, built and commercialized an adaptive cloud infrastructure.

The first part of our series addressed the rationale and business opportunity for TD's cloud-services portfolio, which is built on VMware software. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]

This second installment focuses on how a variety of risks associated with cloud adoption and cloud use have been identified and managed by actual users of cloud services.

Learn more about how adopters of cloud computing have effectively reduced the risks of implementing cloud models. Here to share the story on this journey, we're joined once again by Adam Beavis, General Manager of Cloud Services at Thomas Duryea in Melbourne, Australia.
The question that many organizations keep coming back with is whether they should do cloud computing.

Welcome back, Adam.

Adam Beavis: Thank you, Dana. Pleasure to be here.

Gardner: Adam, we've been talking about cloud computing for years now, and I think it's pretty well established that we can do cloud computing quite well technically. The question that many organizations keep coming back with is whether they should do cloud computing. If there are certain risks, how do they know what risks are important? How do they get through that? What are you in learning so far at TD about risk and how your customers face that?

Beavis: People are becoming more comfortable with the cloud concept as we see cloud becoming more mainstream, but we're seeing two sides to the risks. One is the technical risks, how the applications actually run in the cloud.

Moving off-site

What we're also seeing -- more at a business level -- are concerns like privacy, security, and maintaining service levels. We're seeing that pop up more and more, where the technical validation of the solution gets signed off from the technical team, but then the concerns begin to move up to board level.

We're seeing intense interest in the availability of the data. How do they control that, now that it's been handed off to a service provider? We're starting to see some of those risks coming more and more from the business side.

Gardner: I've categorized some of these risks over the past few years, and I've put them into four basic buckets. One is the legal side, where there are licenses and service-level agreements (SLAs), issues of ownership, and permissions.

The second would be longevity. That is to say, will the service provider be there for the long term? Will they be a fly-by-the-seat-of-the-pants organization? Are they are going to get bought and maybe merged into something else? Those concerns.

The third bucket I put them in is complexity, and that has to do with the actual software, the technology, and the infrastructure. Is it mature? If it's open source, is there a risk for forking? Is there a risk about who owns that software and is that stable?
One of the big things that the legal team was concerned about was what the service level was going to be, and how they could capture that in a contract.

And then last, the long-term concern, which always comes back, is portability. You mentioned that about the data and the applications. We're thinking now, as we move toward more software-defined data centers, that portability would become less of an issue, but it's still top of mind for many of the people I speak with.

So let's go through these, Adam. Let's start with that legal concern. Do you have any organizations that you can reflect on and say, here is how they did it, here is how they have figured out how to manage these license and control of the IP risks?

Beavis: The legal one is interesting. As a case study, there's a not-for-profit organization for which we were doing some initial assessment work, where we validated the technical risk and evaluated how we were going to access the data once the information was in a cloud. We went through that process, and that went fine, but obviously it then went up to the legal team.

One of the big things that the legal team was concerned about was what the service level agreeement was going to be, and how they could capture that in a contract. Obviously, we have standard SLAs, and being a smaller provider, we're flexible with some of those service levels to meet their needs.

But the one that they really started to get concerned about was data availability ... if something were to go wrong with the organization. It probably jumps into longevity a little bit there. What if something went wrong and the organization vanished overnight? What would happen with their data?

Escrow clause

That's where we see legal teams getting involved and starting to put in things like the escrow clause, similar to what we had with software as a service (SaaS) for a long time. We're starting to see organizations' legal firms focus on doing these, and not just for SaaS -- but infrastructure as a service (IaaS) as well. It provides a way for user organizations to access their data if provider organizations like TD were to go down.

Beavis
So that's one that we're seeing at the legal level. Around the terms and conditions, once again being a small service provider, we have a little more flexibility in what we can provide to the organizations on those.

Once our legal team sits down and agrees on what they're looking for and what we can do for them, we're able to make changes. With larger organizations, where SLAs are often set in stone, there's no flexibility about making modifications to those contracts to suit the customer.

Gardner: Let's pause here for a second and learn more about TD for those listeners who might be new to our series. Tell us about your organization, how big you are, and who your customers are, and then we'll get back into some of these risks issues and how they have been managed.

Beavis: Traditionally, we came from a system-integrator background, based on the east coast of Australia -- Melbourne and Sydney. The organization has been around for 12 years and had a huge amount of success in that infrastructure services arena, initially with VMware.
Being a small service provider, we have a little more flexibility in what we can provide to the organizations.

Other companies heavily expanded into the enterprise information systems area. We still have a large focus on infrastructure, and more recently, cloud. We've had a lot of success with the cloud, mainly because we can combine that with a managed services.

We go to market with cloud. It's not just a platform where people come and dump data or an application. A lot of the customers that come into our cloud have some sort of managed service on top of that, and that's where we're starting to have a lot of success.

As we spoke about in part one, our customers drove us to start building a cloud platform. They can see the benefits of cloud, but they also wanted to ensure that for the cloud they were moving to, they had an organization that could support them beyond the infrastructure.

That might be looking after their operating systems, looking after some of their applications such as Citrix, etc. that we specialize in, looking after their Microsoft Exchange servers, once they move it to the cloud and then attaching those applications. That's where we are. That's the cloud at the moment.

Gardner: Just quickly revisiting those legal issues, are you finding that this requires collaboration and flexibility from both parties, learning the road that assuages risks for one party, but protects the other? Is this a back and forth activity? This surely requires some agility, but also some openness. Tell me about the culture at TD that allows you to do that well.

Personality types

Beavis: It does, because we're dealing with different personality types. The technical teams understand cloud and some love it and push for it. But once you get up to that corporate board level, the business level, some of the people up there may not understand cloud -- and might perceive it as more of a risk.

Once again, that's where that flexibility of a company like TD comes in. Our culture has always been "customers first," and we build the business around the longevity of their licenses. That's one of the core, underlying values of TD.

We make sure that we work with customers, so they are comfortable. If someone in the business at that level isn't happy, and we think it might have been the contract, we'll work with them. Our legal team will work with them to make sure we can iron that out, so that when they move across to cloud, everybody is comfortable with what the terms and conditions are.

Gardner: Moving toward this issue of longevity -- I suppose stability is another way to look at it -- is there something about the platform and industry-standard decisions that you've made that helps your customers feel more comfortable? Do they see less risk because, even though your organization is one organization, the infrastructure, is broader, and there's some stability about that that comes to the table?

Beavis: Definitely. Partnering with VMware was one of our core decisions, because their platform everywhere is end-to-end standard VMware. It really gives us an advantage when addressing that risk if organizations ask what happens if our company doesn't run or they're not happy with the service.
It's something that SaaS organizations have been doing for a long time, and we’re only just starting to see it more and more now when it comes to IaaS.

The great thing is that within our environment -- and it's one part of VMware’s vision -- you can then pick up those applications, and move them to another VMware cloud provider. Thank heaven, we haven't had that happen, and we intend it not to happen. But, for organizations to understand that, if something were to go wrong, they can move that to another service provider without having to re-architect those applications or make any major changes. This is one area where we're well getting around that longevity risk discussion.

Gardner: Any examples come to mind of organizations that have come to you with that sort of a question? Is there any sort of an example we can provide for how they were reducing the risk in their own minds, once they understood that extensibility of the standard platform?

Beavis: Once again, it was a not-for-profit organization recently where that happened. We documented the platform. We then gave them the advice of the escrow organizations, where they would have an end-to-end process. If something were to happen to TD, they would have an end-to-end process of how they would get their data, and have it restored on another cloud provider -- all running on common VMware infrastructure.

That made them more comfortable with what we were offering, the fact that there was a way out that that would not disappear. As I said, it's something that SaaS organizations have been doing for a long time, and we’re only just starting to see it more and more now when it comes to IaaS and cloud hosting.

Gardner: Now the converse of that would be that some of your customers who have been dabbling in cloud infrastructure, perhaps open-source frameworks of some kind, or maybe they have been integrating their own components of open-source available software, licensed software. What have you found when it comes to their sense of risk, and how does that compare to what we just described in terms of having stability and longevity?

More comfortable

Beavis: Especially in Australia, we probably have 85 percent to 90 percent of organizations with some sort of VMware in their data center. They no doubt seem to be more comfortable gravitating to some providers that are running familiar platforms, with teams familiar with VMware. They're more comfortable that we, as a service provider, are running a platform that they're used to.

We'll probably talk about the hybrid cloud a bit later on, but that ability for them to still maintain control in a familiar environment, while running some applications across in the TD cloud, is something that is becoming quite welcoming within organizations. So there's no doubt that choosing a common platform that they're used to working on is giving them confidence to start to move to the cloud.

Gardner: Do you have any examples of organizations that may have been concerned about platforms or code forking -- or of not having control of the maturity around the platform? Are there any real-life situations where the choice had to be made, weighing the pros and cons, but then coming down on the side of the established and understood platform?

Beavis: More organizations aren’t promoting what their platform is, and we’re not quite sure that it could be built on OpenStack or other platforms. We're not quite sure what they're running underneath.

We've had some customers say that some service providers aren’t revealing exactly what their platform is, and that was a concern to them. So it's not directed to any other platforms, but there's no doubt that some customers still want to understand what the underlying infrastructure is, and I think that will remain for quite a while.
As they are moving into cloud for the first time, people do want to know what that platform sitting there underneath is.

At the moment, as they are moving into cloud for the first time, people do want to know what that platform underneath is.

It also comes down to knowing where the data is going to sit as well. That's probably the big one we’re seeing more and more. That's been a bit of a surprise to me, the concerns people certainly have around things like data sovereignty and the Patriot Act. People are quite concerned about that, mainly because their legal teams are dictating to them where the data must reside. That can be anything from being state based or country based, where the data cannot leave the region that's been specified.

Gardner: I suppose this is a good segue into this notion of how to make your data, applications, and the configuration metadata portable across different organizations, based on some kind of a standard or definition. How does that work? What are the ways in which organizations are asking for and getting risk reduction around this concept of portability?

Beavis: Once again, it's about having a common way that the data can move across. The basics come into that hybrid-cloud model initially, like how people are getting things out. One of the things that we see more and more is that it's not as simple as people moving legacy applications and things up to the cloud.

To reduce that risk, we're doing a cloud-readiness assessment, where we come in and assess what the organization has, what their environment looks like, and what's happening within the environment, running things like the vCenter Operations tools from VMware to right-size those environments to be ready for the cloud.

Old data

We’re seeing a lot of that, because there's no point moving a ton of data out there, and putting it on live platforms that are going to cost quite a bit of money, if it's two or four years old. We’re seeing a lot of solution architects out there setting those environments before they move up.

Gardner: Is there a confluence between portability and what organizations are doing with disaster recovery (DR)? Maybe they're mirroring data and/or infrastructure and applications for purposes of business continuity and then are able to say, "This reduces our risk, because not only do we have better DR and business continuity benefits, but we’re also setting the stage for us to be able to move this where we want, when we want."

They can create a hybrid model, where they can pick and choose on-premises, versus a variety of other cloud providers, and even decide on those geographic or compliance issues as to where they actually physically place the data. That's a big question, but the issue is business continuity, as part of this movement toward a lower risk, how does that pan out?

Beavis: That's actually one of the biggest movements that we’re seeing at the moment. Organizations, when they refresh their infrastructure, don’t see the the value refreshing DR on-premise. Let the first step cloud be "let's move the DR out to the cloud, and replicate from on-premises out into our cloud."

Then, as you said, we have the advantage to start to do things like IaaS testing, understanding how those applications are going to work in the cloud, tweak them, get the performance right, and do that with little risk to the business. Obviously, the production machine will continue to run on-premises, while we're testing snapshots.
DR is still the number one use case that we're seeing people move to the cloud.

It's a good way to put a live snapshot of that environment, and how it’s going to perform in the cloud, how your users are going to access it, bandwidth, and all that type of stuff that you need to do before starting to run up. DR is still the number one use case that we’re seeing people move to the cloud.

Gardner: As we go through each of these risks, and I hear you relating how your customers and TD, your own organization, have reacted to them, it seems to me that, as we move toward this software-defined data center, where we can move from the physical hardware and the physical facilities, and move things around in functional blocks, this really solves a lot of these risk issues.

You can manage your legal, your SLAs, and your licenses better when you know that you can pick and choose the location. That longevity issue is solved, when you know you can move the entire block, even if it's under escrow, or whatever. Complexity and fear about forking or immaturity of the infrastructure itself can be mitigated, when you know that you can pick and choose, and that it's highly portable.

It's a round-about way of getting to the point of this whole notion of software-defined data center. Is that really at heart a risk reduction, a future direction, that will mitigate a lot of these issues that are holding people back from adopting cloud more aggressively?

Beavis: From a service provider's perspective it certainly does. The single-pane management window that you can do now, where you can control everything from your network -- the compute and the storage -- certainly reduces risk, rather than needing several tools to do that.

Backup integration

And the other area where the venders are starting to work together is the integration of things like backup, and as we spoke about earlier, DR. Tools are now sitting natively within that VMware stack around the software-defined data center, written to the vSphere API, as we're trying to retrofit products to achieve file-level backups within a virtual data center, within vCloud. Pretty much every day, you wake up there's a new tool that's now supported within that.

From a service provider's perspective it's really reducing the risk and time to market for the new offerings, but from a customer's perspective it's really getting in that experience that they used to. On-premise over a TD cloud, from their perspective, makes it a lot easier for them to start to adopt and consume the cloud.

Gardner: One last chance, Adam, for any examples. Are there any other companies that you would like to bring up that illustrate some of these risk-mitigation approaches that we've been discussing?

Beavis: Another one was a company, a medical organization. It goes back to what we were saying earlier. They had to get a DR project up and running. So they moved that piece to the cloud, and were unsure whether they would ever move any of their production data out. But six months after running DR in the cloud, we just started to provide some capacity.

The next thing was that they had a new project, putting in a new portal for e-learning. They decided for the first time, "We've got the capacity seeing over in the cloud. Let's start to do that." So they’ve started to migrate all their test and dev environment out there, because in their mind they reduced the risk around the up time in the cloud due to the success that had with the DR. They had all the statistics in reporting back on the stability of that environment.

Then, they became comfortable to move the next segment, which was the test and dev environment. And all things are going well. That application will run out of the cloud and will be their first application out there.
We have the team here that can really make sure we architect or build those apps correctly as they start to move them out.

That was a company that was very risk averse, and the DR project took a lot of getting across the line in the first case. We'll probably see that, in six to eight months, they're going to be running some of their core applications out of the cloud.

We'll start to see that more and more. The customers’ roadmap to the cloud will move from DR, maybe some test and dev, and new applications. Then, as that refresh comes up to the on-premise, they would be in a situation where they have completed the testing for those applications and feel comfortable to move them out to the cloud.

Gardner: That really sounds like an approach to mitigating risk, when it comes to the cloud, gradual adoption, learn, test, and then reapply.

Beavis: It is, and one of the big advantages we have at TD is the support around a lot of those applications, as people move out -- how Citrix is going to work in the cloud, how Microsoft Exchange is going to work in the cloud, and how their other applications will work. We have the team here that can really make sure we architect or build those apps correctly as they start to move them out.

So a lot of customers are comfortable to have a full-service service provider, rather than just a platform for them to throw everything across.

Gardner: Great. We've been discussing how a leading Australian IT service provider, Thomas Duryea Consulting, has made a successful journey to cloud computing. This sponsored second installment on how a variety of risks associated with cloud adoption have been identified and managed, comes via a three-part series on how TD designed, built and commercialized a vast cloud infrastructure built on VMware.

We've seen how, through a series of use case scenarios, a list of risks has been managed. And we also developed a sense of where risk as a roadmap can be balanced in terms of starting with disaster recovery and then learning from there. I thought there was really an interesting new insight to the market.

So look for the third and final chapter in our series soon, and we'll then explore the paybacks and future benefits that a cloud ecosystem provides for businesses. We'll actually examine the economics that compel cloud adoption.

With that, I’d like to thank our guest Adam Beavis, the General Manager of Cloud Services at Thomas Duryea Consulting in Melbourne, Australia. This was great, Adam. Thanks so much.

Beavis: Absolute pleasure.

Gardner: And of course, I would like to thank you, our audience, for joining as well. This is Dana Gardner, Principal Analyst at Interarbor Solutions.

Dana Gardner: Hi, this is Dana Gardner, Principal Analyst at Interarbor Solutions, and you're listening to BriefingsDirect.

Today, we present a sponsored podcast discussion on the intriguing concept of the software-defined datacenter. We'll look at how some of the most important attributes of datacenter capabilities and performance are now squarely under the domain of software enablement.

We'll see how those who are now building and managing datacenters are gaining heightened productivity, delivering far better performance, and enjoying greater ease in operations and management -- all thanks to innovations at the software-infrastructure level.

A top technology leader at VMware, Steve Herrod has championed this vision of the software-defined datacenter and how the next generation of foundational IT innovation is largely being implemented above the hardware. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]

We're here with him now to further explore how advances in datacenter technologies and architecture are, to an unprecedented extent, being driven primarily through software. Please join me in welcoming to BriefingsDirect, Steve Herrod, Chief Technology Officer and Senior Vice President of Research & Development at VMware. Welcome, Steve.

Steve Herrod: Thanks, Dana. It’s a great topic. I'm really looking forward to sharing some thoughts on it.

Gardner: We appreciate your being here. We've heard a lot over the decades about improving IT capabilities and infrastructure management, but it seems that many times we peel back a layer of complexity and we get some benefits, and we find ourselves like the proverbial onion, back at yet another layer of complexity.

Complexity seems to be a recurring inhibitor. I wonder if this time we're actually at a point where something is significantly different. Are we really gaining ground against complexity at this point?

Herrod: It’s a great question, because complexity is associated with IT and why we'll do it differently this time. I see two things happening right now that give us a great shot at this.

One is purely on expectations. All of the opportunities we have as consumers to work with cloud computing models have opened up our imagination as to what we should expect out of IT and computing datacenters, where we can sign up for things immediately, get things when we want them, and pay for what we use. All those great concepts have set our expectations differently.

A good shot

Simultaneously, a lot of changes on the technology side give us a good shot at implementing it. When you combine technology that we'll talk about with the loosened-up imagination on what can be, we're in a great spot to deliver the software-defined datacenter.

Gardner: You mentioned cloud and this notion that it’s a liberating influence. Is this coming from the technologists or from the business side? Is there a commingling on that concept quite yet?

Herrod: It’s funny. I see it coming from the business side, which is the expectation of an individual business unit launching a product. They now have alternatives to their own IT department. They could go sign up for some sort of compute service or software-as-a-service (SaaS) application. They have choices and alternatives to circumvent IT. That's an option they didn't have in the past.

Fundamentally, it comes down to each of us as individuals and our expectations. People are listening to this podcast when they want to, quickly downloading it. This also applies to signing up for email, watching movies, and buying an app on an app store. It's just expected now that you can do things far more agilely, far more quickly than you could in the past, and that's really the big difference.

Gardner: Steve, folks are getting higher expectations based on what they encounter on their consumer side of technology consumption. We see what the datacenters are capable of from the likes of Google and Facebook. Is it possible for enterprises to also project that sort of productivity and performance onto what they're doing, and maybe now that we've gone through an iteration of these vast datacenters, to do it even better?

Herrod: I have a lot of friends at Facebook, Zynga, and Google, running the datacenters there, and what’s exciting for me is that they have built a fully software-defined datacenter. They're doing a lot of the things we are talking about here. But there are two unique things about their datacenters.

When you go into the business world, they don't have legions of people to run the infrastructure.



One is that they have hundreds or even thousands of PhDs who are running this infrastructure. Second, they're running it for a very specific type of application. To run on the Google datacenter, you write your applications a very specific way, which is great for them. But when you go into the business world, they don't have legions of people to run the infrastructure, and they also have a broad set of applications that they can’t possibly consider rewriting.

So in many ways, I see what we're doing is taking the lesson learned in those software-defined datacenters, but bringing it to the masses, and bringing it to companies to run all of their applications and without all of the people cost that they might need otherwise.

Gardner: Let’s step back for some context. How did we get here? It seems that hardware has been sort of the cutting edge of productivity, when we think of Moore’s Law and we look at the way that storage, networks, and server architecture have come together to give us the speeds and feeds that have led to a lot of what we take for granted now. Let’s go through that a little bit and think about why we're at a point where that might not be the case anymore.

Herrod: I like to look at how we got to where we are. I think that's the key to understanding where we're likely to go from here.

History of IT decisions

W
e started VMware out of a university, where we could take the time to study history and look at what had happened. I liked looking at existing datacenters. You can look through the datacenter and see the history of IT decisions of the past.

It's traditionally been the case that a particular new need led the IT department to go out and buy the right infrastructure for that new need, whether it’s batch processing, client/server applications, or big web farms. But these individually made decisions ended up creating the silos that we all know about that exist all over datacenters.

They now have the group that manages the mainframe, the UNIX administration group, and the client PC group, and none of them is using common people or common tools as much as they certainly would like to. How we got to where we are were isolated decisions for the right thing at the right time, without recognizing the opportunity to optimize across a broader set of the datacenter.

The whole concept of software-defined datacenters is looking holistically at all of the different resources you have and making them equally accessible to a lot of different application types.

Gardner: Earlier, I used the metaphor of an onion. You peel back complexity and you get more. But when it comes to the architecture of datacenters, it seems that the right comparison might be a snowball, which is layered on another layer, or it has been rolling and gathering as it goes, but not rationalized, not looked at holistically.

Every single day you hear about a new case where a business unit or an employee is able to circumvent IT to scratch the itch they have for some particular type of technology.



Are there some sorts of imperatives now that are driving people to do that? We talked about the cloud vision, but maybe it’s security, maybe it’s the economics, maybe it’s the energy issues, or maybe it's all those things together.

Herrod: It’s a little of each. First of all, I like the onion analogy, because it makes you cry, and I think that’s also key. But it’s a combination of requirements coming in at the same time that's really causing people to look at it.

Going back to the original discussion, it starts with the fact that there are choices now. Every single day you hear about a new case where a business unit or an employee is able to circumvent IT to scratch the itch they have for some particular type of technology, whether it's using Dropbox instead of the file servers that the company has, buying their own device and bringing it in, or just signing up for Amazon EC2, instead of using their local datacenter. These are all examples of them being able to go around IT.

But what often happens subsequently is that, when a security problem happens, when you realize that you are not in compliance, IT is left holding the bag. So we get an environment here where the user demand can be handled other ways, but IT has to be able to compete with those.

We have to let IT be a service provider and be able to be as responsive with those, so that they can avoid people going around them. But they still need to be responsible to the business when it comes time to show that Sarbanes-Oxley (SOX) compliance is appropriate or to make sure that your customer records aren’t leaked out to everyone else on the Internet.

That unique balance between the user choice and IT control is something we've all seen over the last several decades, and it’s showing up again at an even larger state.

New competition


Gardner: As you pointed out, Steve, IT isn’t just competing against itself. That is to say, maybe a 5 percent or 10 percent improvement over how well it did last year will be viewed as very progressive. But they're competing now against other datacenter architects. Maybe it’s a SaaS provider, maybe it’s a cloud provider, maybe it’s managed service provider (MSP) or telco that's now offering additional services.

We're really up against this notion that if you don’t architect your datacenter with that holistic software-defined mentality, and someone else does that, you're in trouble.

Herrod: It’s a great point. There are rate cards now for what you can use something else for. You might pay 7 cents per hour for this, or "this much" per transaction. IT departments in general have not traditionally had a good way of, first, even knowing how much they are costing, but second, optimizing to be competitive. So there's this awareness now of how much I'm spending and how long it takes. These metrics are causing this.

Gardner: Let’s revisit the context and the history here, looking at virtualization in particular. We've seen it extend beyond servers to data, storage, and also networking. Is this part of what you've got in your vision of software defined? Is it strictly virtualization, or does it encompass more? Help me understand how you've progressed in your thinking along these lines, particularly in regard to virtualization?

Herrod: We'll step back a little bit. VMware, over the last 13 years or so, has done a very good job of completely optimizing how servers are used in the datacenter. You can provision a new virtual machine (VM) in seconds. The cost has gone down in orders of magnitude. We've really done a good job on the compute and memory aspect of a datacenter.

It's absolutely crucial to look at the breadth of things that are involved in the datacenter.



But as you said, a couple of things have to happen from there. It's absolutely crucial to look at the breadth of things that are involved in the datacenter. We talk to customers now, and often they say, "Great, you've just lowered the cost and time taken to provision a new server. But when I put this in production, by the way, I care what LUN it ends up on, I have to look at what VLAN is there, and if it's in the right section of my firewall setup."

It might take seconds to provision a VM, but then it takes five days to get the rest of the solutions around it. So we see, first of all, the need to get the entire datacenter to be as flexible and fast moving as the pure server components are right now.

Again, if you look at the last couple of years, I would rate the industry -- ourselves and others -- as moving forward quite well on the storage side of things. There are still some things to do for sure, but storage, for the most part, has gotten a good head start on being fully virtualized and automated.

The big buzz around the industry right now has been the recognition that the network is the huge remaining barrier to doing what you want in your datacenter. Plenty of startups and all kinds of folks are working on software-defined networking. In fact, that's what we use as the term for the software-defined datacenter, because as networking follows as this big inhibitor, you'll be opened up to having a truly planned datacenter solution in place.

Now, we can break that down a little bit. It's important to talk about the technology piece of this. But when I say software-defined, I really look at three phases of how software comes in and morphs this existing hardware that you have.

The first step

The first step is to abstract away what people are trying to use from how it is being implemented. That's the core of what virtual even means, separating the logical from the physical. It gives you hardware independence. It enables basic mobility and all sorts of other good things.

The second phase is when you then pool all of these abstracted resources into what we call resource pools. Anyone who uses VMware software knows that we create these great clusters of computing horsepower and we allow vMotion and mobility within it.

But you need to think about that same notion of aggregation of resources at the storage and networking levels, so they become this great pool of horsepower that you can then dole out quite effectively. So after you've abstracted and pooled, the final phase is how you now automate the handling of this. This is where the real savings and speed come from.

Once you have pools of resources, when a new request comes in, you should be able to allocate storage, security, networking, and CPU very quickly. Likewise, when it goes away, you should be able to remove it and put it back into the pool.

That's a bit of a mouthful, but that's how I see the expansion. It first goes from just compute into storage, networking, security, and the other parts of the datacenter. Then simultaneously, you're abstracting each of these resources, pooling them, and then automating them.

When a new request comes in, you should be able to allocate storage, security, networking, and CPU very quickly.



Gardner: What's really fascinating to me are the benefits you get by abstracting to a virtualization and software-defined level -- the ability to implement with greater ease -- but that comes with underlying benefits around operations and management.

It seems to me that you can start to dial up and down, demonstrate elasticity at a far greater level, almost at that data-center level, looking at the service-level agreements (SLAs) and the key performance indicators (KPIs) that you need to adhere to and defining your datacenter success through a business metric, like an SLA.

Does it ring true with you that we're talking about some real management and operational efficiencies, as well as implementation efficiencies?

Herrod: It is, Dana, and we talk about it a few different ways. The transformation of datacenters, as we got started, was all about cost savings and capital expenses in financial terms. Let's buy fewer servers. "Let's not build another datacenter."

But the second phase, and where most customers are today, is all about operational efficiency. Not only am I buying less hardware, but I can do things where I'm actually able to satisfy, as you said, the KPIs or the SLAs.

Doing even more


I
can make sure that applications are up and running with the level of availability they expect, with less effort, with fewer people, and with easier tools. And when you go from capital expense savings to operational improvements, you impact the ability for IT to do even more.

To take that one level further, whenever I hear people talk about cloud computing -- and everyone talks about this with all sorts of different impressions in mind -- I think of cloud as simply being about more speed. You can do something more quickly. You can expand something more quickly. And that's what this third phase after capital and operational savings is about, that agility to move faster.

As businesses’ success ties so closely to how IT does, the ability to move faster becomes your strategic weapon against someone else. Very core to all this is how can we operate more efficiently, while satisfying the specific needs of applications in this new datacenter.

Gardner: Another area that I hear about benefiting from this software defined datacenter is the ability to better reduce and manage risk, particularly around security issues. You're no longer dealing with multiple parties, like the group overseeing UNIX, the group overseeing PC, the group doing the x86 architectures. The likelihood for process cracks to develop and security issues to unfortunately crop up seem to be more likely under those circumstances.

But when you have got a more organized overview of management operations and architecting at a similar level, you can instantiate the best practices around security. Please address this issue of security as another fruit to be harvested from a software-defined datacenter.

Security means a lot of different things, and it has been affected by a number of different aspects.



Herrod: Security means a lot of different things, and it has been affected by a number of different aspects.

First of all, I agree that the more you can have a homogenous platform or a homogenous team working on something, the less variation and process you end up with, exactly as you said, Dana. That can allow you to be more efficient.

This is a replacement for the traditional world of ITIL, where they had to try to create some standard across very different back ends. That's a natural progression for getting rid of some of the human errors that come into problems.

A more foundational thing that I am excited about with the software-defined datacenter is how, rather than security being these physical concepts that are deployed across the datacenter today, you can really think of security logically as wrapping up your application. You can do some pretty interesting new things.

A quick segue on that -- the way most security works in datacenters today is through statically placed appliances, whether they're firewalls, intrusion detection, or something else. Then the onus is on you to fit your application in the right part of the datacenter to get the right level of protection that you have, and hopefully it doesn’t move out of that protection zone.

Follows the application

What we're able to deliver with the software-defined datacenter is a way that security is a trait associated with the application, and it essentially wraps and follows the application around. You've virtualized your firewall and you've built it into the fabric of how you're automating deployments. I see that as a way to change the game on how tight the security can be around an application, as well as making sure it's always around there when you deploy it.

Gardner: For end users the proof is in how they actually consume, relate to, and interact with the applications. Is there something about the applications specifically that the software-defined datacenter brings, a higher level of user productivity benefits? What's really going to be noticeable for the application level to end users?

Herrod: That's a great question. I'm an infrastructure guy, as are probably many people listening here, and it’s easy to forget that infrastructure is simply a means to an end. It's the way that you run applications that ultimately matters. So you have to look at what an application is and what its ideal state looks like. The idea of the software-defined datacenter is to optimize that application experience.

That very quickly translates into how quickly can I get my application from the time I want it until it's running. It dictates how often this application is up, what kind of scale it can handle as more people come in, and how secure it is. Ultimately, it's about the application. I believe the software-defined datacenter is the way to optimize that application experience for all the users.

Gardner: Steve, how about not just repaving cow paths in terms of how we deploy existing types of applications. Is there something inherent in a software-defined datacenter benefit that will work to our advantage on innovative new types of applications?

We are at a point where, depending on who you listen to, about 60 percent of all server applications are running virtual.



They could be for high performance computing, big data and analytics, or even when we go to mobile and we have location services folded into some of the way that applications are served up, and there is sort of a latency sensitive portion to this. Are there new types of apps that will benefit from this software-defined architecture?

Herrod: This is one of the most profound parts, if we get it right. I've been talking about can we collapse the silos that were created. Can we get all of our existing apps onto this common platform? We're doing quite well on that. We are at a point where, depending on who you listen to, about 60 percent of all server applications are running virtual, which is pretty amazing. But that also means there is 40 percent that aren’t. So I spend a lot of time understanding why they might not be today.

Part of it is that just as businesses get more comfortable and get there, their business critical apps will get onto the system, and that's working well. But there are applications that are emerging, as you talked about, where if we're not careful, they'll create the next generation of silos that we'll be talking about 10 years from now.

I see this all the time. I'll visit a company that has a purely virtualized pool, but they have also created their grid for doing some sort of Monte Carlo simulations or high-performance computing. Or they have virtualized everything except for their unified communication environment, which has a special team and hardware allocated to it.

We spend quite a bit of time right now looking at the impediments to having those run on top of virtualization, which might be performance related or something else. Then going beyond impediments to how can we make them even better when they are run on top of the virtualized platform.

Great applications


Some of the really interesting things we're able to show now with our partners are things I would have never dreamed of as great candidates when we started the company. But we're able to satisfy very strict real-time requirements, which means we can run some great applications used in various sorts of stock trading, but also used in things like voice over IP (VoIP) or video conferencing.

Another big area that's liable to create the next round of silos, if we're not careful, is the big data and Hadoop world. Lots of customers are kicking the tires and creating special clusters and teams to work on that. But just recently, we've shown that the performance of Hadoop on top of vSphere, our virtualization platform, can be great.

We can even show that we can make it far easier to set up. We can make Hadoop more available, meaning it won’t crash as often. And we can even do things where we make it more elastic than it already is. It can suck up as many resources in the software-defined datacenter as it wants, when it needs them, but it can also give them all back when it's not using them.

It’s really exciting to look across all these apps. At this point, I don’t see a reason why we can't get almost any type app that we're looking at today to fit into the software-defined datacenter model.

Gardner: That’s exciting, when we don’t have any of the stragglers or large portions of business functions that are cast off. It seems to me that we've reached the capability of mirroring the entire datacenter, whether it’s for purposes of business continuity or disaster recovery (DR), or backup and recovery. It gives us the choice of where to locate these resources, not at the individual server, virtual machine level, or application level, but really to move the whole darn datacenter, if that’s important, without a penalty.

Very rapidly, this notion of DR has been a driving reason for people to virtualize their datacenter.



For our last blue-sky direction with this conversation, are we at the point where we have fungibility, if you will, of datacenters, or are we getting to that point in the near future, where we can decide at a moment’s notice where we're going to actually put our datacenter, almost location independent?

Herrod: It’s a ways out, before we're just casually moving datacenters around, for sure. But I have seen some use cases today that are showing what's possible, and maybe I'll just give you a couple of examples.

DR has long been one of the real pains for IT to deal with. They have to replicate things across the country and keep two datacenters completely in sync, literally the same hardware, the same firmware layer, and all of that that goes into it.

Very rapidly, this notion of DR has been a driving reason for people to virtualize their datacenter. We have seen many cases now, where you're able to failover your entire datacenter, effectively copying the whole datacenter over to another one, keeping the logical constructs in place, but hosting in a completely different area.

To get that right, your storage needs to be moved, your network identities need to be updated, and those are things that you can script and do in an automated way, once you've virtualized the whole datacenter.

Fun example


A
nother really fun example I see more and more now is, as mergers and acquisitions happen, we've seen several cases where one company buys another. They both had fully virtualized their datacenter and they could put on a giant storage drive the datacenter at one company and begin to bring it up on the other side, once they copied it over there.

So the entire datacenter isn't moved yet, but I think there are clear indications of once you separate out where something runs and how it runs from what you are really after, it opens up the door for a lot of different optimizations.

Gardner: We're coming up on the end of our time, but we also have the big annual VMworld show in San Francisco coming up toward the end of August. I know you can’t pre-announce anything, but perhaps you can give us some themes. We've talked about a lot of things here today, but is there any particular themes that we have hit on that you think are going to be more impactful or more important in terms of what we should expect at VMworld?

Herrod: It will be exciting as always. We have more than 20,000 people expected. What I'm doing here is talking about a vision and generalities of what's happening, but you can certainly imagine that what we will be showing there will be the realities -- the products that prove this, the partnerships that are in place that can help bring it forward, and even some use cases and some success stories.

You need to get to the point where you are leveraging the full automation and mobility that exists today.



So expect it to be certainly giving more detail around this vision and making it very real with announcements and demonstrations.

Gardner: Last question, if I'm a listener here today, I'm intrigued, and I want to start thinking about the datacenter at the software-defined level in order to generate some of the benefits that we have been discussing and some of the vision that we have been painting, what’s a good way to start? How do you begin this process? What are a few foundational directives or directions that you recommend?

Herrod: I think it can sound very, very disruptive to create a new software-defined datacenter, but one of the biggest things that I have been excited about in this technology versus others is that there are a set of steps that you go through, where you're able to get some value along the way, but they are also marching you toward where you ultimately end up.

So to customers who are doing this, presumably most of you have done some basic virtualization, but really you need to get to the point where you are leveraging the full automation and mobility that exists today.

Once you start doing that, you'll find that it obviously is showing you where things can head. But it also changes some of the processes you use at the company, some of the organizational structures that you have there, and you can start to pave the way for the overall datacenter to be virtualized, as you take some of these initial steps.

It’s actually very easy to get started. You can make benefits along the way. Your existing applications and hardware work. So that would be my real entreaty -- use what exists today and get your feet wet, as we deliver the next round heading forward.

Gardner: We've been talking about the intriguing concept of the software-defined datacenter and we've been exploring how advances in datacenter technologies and architectural benefits that are being driven through software innovation can provide a number of technological and business benefits.
