Dana Gardner: Hello, and welcome to a special BriefingsDirect podcast series coming to you from the VMworld 2011 Conference. We're here to explore the latest in cloud computing and virtualization infrastructure developments.
I'm Dana Gardner, Principal Analyst at Interarbor Solutions, and I’ll be your host throughout this series of VMware-sponsored BriefingsDirect discussions.
Our next VMware case study interview focuses on the City of Fairfield, California, and how the IT organization there has leveraged virtualization and cloud-delivered applications to provide new levels of service in an increasingly efficient manner.
We’ll see how Fairfield, a mid-sized city of 110,000 in Northern California, has taken the do-more-with-less adage to its fullest, beginning interestingly with core and mission-critical city services applications.
Please join me now in welcoming Eudora Sindicic, Senior IT Analyst Over Operations in Fairfield. Welcome to the show, Eudora.
Eudora Sindicic: Thank you very much.
Gardner: I'm really curious, why did you choose to move forward with virtualization on your core applications, mission-critical level applications, things like police support and fire department support? What made you so confident that those were the right apps to go with?
Sindicic: First of all, it’s always been challenging in disaster recovery and business continuity. Keeping those things in mind, our CAD/RMS systems for the police center and also our fire staffing system were high on the list for protecting. Those are Tier 1 applications that we want to be able to recover very quickly.
We thought the best way to do that was to virtualize them and set us up for future business continuity and true failover and disaster recovery.
So I put it to my CIO, and he okayed it. We went forward with VMware, because we saw they had the best, most robust, and mature applications to support us. Seeing that our back-end was SQL for those two systems, and seeing that we were just going to embark on a brand-new upgrading of our CAD/RMS system, this was a prime time to jump on the bandwagon and do it.
Also, with our back-end storage being NetApp, and NetApp having such an intimate relationship with VMware, we decided to go with VMware.
Gardner: And how has that worked out?
Sindicic: It’s been wonderful. We’ve had wonderful disaster recovery capabilities. We have snapshotting abilities. I'm snapshotting the primary database server and application server, which allows for snapshots up to three weeks in primary storage and six months on secondary storage, which is really nice, and it has served us well.
We already had a fire drill, where one report was accidentally deleted out of a database due to someone doing something -- and I'll leave it at that. Within 10 minutes, I was able to bring up the snapshot of the records management system of that database.
The user was able to go into the test database, retrieve his document, and then he was able to print it. I was able to export that document and then re-import it into the production system. So there was no downtime. It literally took 10 minutes, and everybody was happy.
Gardner: So you were able to accomplish your virtualization and also gain that disaster recovery and business continuity benefit, but you pointed out the time was of the essence. How long did it take you, and was that ahead of schedule, behind schedule? How that affects you in terms of timing?.
Sindicic: Back in early fiscal year 2010, I started doing all the research. I probably did a good nine months of research before even bringing this option to my CIO. Once I brought the option up, I worked with my vendors, VMware and NetApp, to obtain best pricing for the solution that I wanted.
I started implementation in October and completed the process in March. So it took some time. Then we went live with our CAD/RMS system on May 10, and it has been very robust and running beautifully ever since.
Gardner: Tell me about your apparatus, your IT operations, the number of servers, the level of virtualization that you’re using. Then, we’d like to hear about some of the additional apps you may be bringing on or have brought on.
Sindicic: I have our finance system, an Oracle-based system, which consists of an Oracle database server and Apache applications server, and another reporting server that runs on a different platform. Those will all be virtual OSs sitting in one of my two clusters.
For the police systems, I have a separate cluster just for police and fire. Then, in the regular day-to-day business, like finance and other applications that the city uses, I have a campus cluster to keep those things separated and to also relieve any downtime of maintenance. So everything doesn’t have to be affected if I'm moving virtual servers among systems and patching and doing updates.
We’re also going to be virtualizing several other applications, such as a citizen complaint application called Coplogic. We're going to be putting that in as well into the PD cluster.
The version of VMware that we’re using is 4.1, we’re using ESXi server. On the PD cluster, I have two ESXi servers and on my campus, I have three. I'm using vSphere 4, and it’s been really wonderful having a good handle on that control.
Also, within my vSphere, vCenter server, I've installed a bunch of NetApp storage control solutions that allow me to have centralized control over one level snapshotting and replication. So I can control it all from there. Then vSphere gives me that beautiful centralized view of all my VMs and resources being consumed.
It’s been really wonderful to be able to have that level of view into my infrastructure, whereas when the things were distributed, I hadn’t had that view that I needed. I’d have to connect one by one to each one of my systems to get that level.
Also, there are some things that we’ve learned during this whole thing. I went from two VLANs to four VLANs. When looking at your traffic and the type of traffic that’s going to traverse the VLANs, you want segregate that out big time and you’ll see a huge increase in your performance.
The other thing is making sure that you have the correct type of drives in your storage. I knew that right off the bat that IOPS was going to be an issue and then, of course, connectivity. We’re using Brocade switches to connect to the backend fiber channel drives for the server VMs, and for lower-end storage, we’re using iSCSI.
Gardner: I know you're only a few months into this in terms of being in full production, but in addition to getting some of these benefits around view and analytics into the operations, do you have any metrics of success in terms of lowering the total cost of doing this vis-à-vis your previous physical and distributed approach?
Sindicic: We are seeing cost benefits now. I don’t have all the metrics, but we’ve spun up six additional VMs. If you figure out the cost of the Dells, because we are a Dell shop, it would cost anywhere between $5,000 and $11,000 per server. On top of that, you're talking about the cost of the Microsoft Software Assurance for that operating system. That has saved a lot of money right there in some of the projects that we’re currently embarking on, and for the future.
We have several more systems that I know are going to be coming online and we're going to save in cost. We’re going to save in power. Power consumption, I'm projecting, will slowly go down over time as we add to our VM environment.
As it grows and it becomes more robust, and it will, I'm looking forward to a large cost savings over a 5- to 10-year period.
Gardner: So we’ve seen that you've been able to maintain your mission-critical performance and requirements for these applications. You were able to get better insight into these operations. You were able to cut your costs. And now you’ve set yourself up for being able to extend that value into other applications.
Was there anything that surprised you that you didn’t expect, when you moved from the physical to the virtualized environment?
Sindicic: I was pleasantly surprised, as I said, with the depth of reporting that I could physically see, the graph, the actual metrics, as we were ongoing. As our CAD system came online into production, I could actually see utilization go up and to what level.
I was pleasantly surprised to be able to see to see when the backups would occur, how it would affect the system and the users that were on it. Because of that, we were able to time them so that would be the least-used hours and what those hours were. I could actually tell in the system when it was the least used.
It was real time and it was just really wonderful to be able to easily do that, without having to manually create all the different tracking ends that you have to do within Microsoft Monitor or anything like that. I could do that completely independently of the OS.
Gardner: So better control management and therefore efficiency, being able to decide when things should happen in a more efficient manner. Given the fact that you’re a public organization, have compliance or regulatory issues crept in, and has that been something that’s been beneficial?
Sindicic: Regulatory and compliance is going to creep in. I see that in the future with some of our applications as that rolls into a virtual environment. We're going to have some compliance issues, and it’s mostly around encryption and data control, which I really don’t foresee being a problem with VMware.
They also have a lot of hardening information that I am going to be using and utilizing to harden not only the OS, but you can also encrypt your VM. So I'm looking forward to doing that.
Gardner: Of course, you’re also in the public service business and you have to provide for your users who are those people that are then supporting the people in the community, the proactive public at large. So how has this gone?
Sindicic: Our biggest are our CAD and RMS systems. This is an application that is used in the laptops on all of the squad cars. And so far so good. Everybody seems to be really happy. The response of the application is significant. There haven’t been a lot of issues when it comes to connectivity and response times, all the way down to the unit. So it’s been really nice.
Gardner: That's the right effect I suppose, the right response. We're hearing a lot here at VMworld about desktop virtualization as well. I don’t know whether you’ve looked at that, but it seems like you've set yourself up for moving in that direction. Any thoughts about mobile or virtualized desktops as a future direction for you?
On the horizon
Sindicic: I see that most definitely on the horizon. Right now, the only thing that's hindering us is cost and storage. But as storage goes down, and as more robust technologies come out around storage, such as solid state, and as the price comes down on that, I foresee that something definitely coming into our environment.
Even here at the conference I'm taking a bunch of VDI and VMware View sessions, and I'm looking forward to hopefully starting a new project with virtualizing at the desktop level.
This will give us much more granular control over not only what’s on the user’s desktop, but patch management and malware and virus protection, instead of at the PC level doing it the host level, which would be wonderful. It would give us really great control and hopefully decreased cost. We’d be using a different product than probably what we’re using right now.
If you're actually using virus protection at the host level, you’re going to get a lot of bang for your buck and you won't have any impact on the PC-over-IP. That’s probably the way we we'll go, with PC-over-IP.
Right now, storage, VLANing all that has to happen, before we can even embark on something like that. So there's still a lot of research on my part going on, as well as finding a way to mitigate costs, maybe trade-in, something to gain something else. There are things that you can do to help make something like this happen.
Gardner: It certainly sounds like the more you’re able to learn and develop competency and implementation experience, the more you can then take advantage of some of the other efficiencies and it's almost as if there is a sort of a snowball effect here around productivity. Is that a fair characterization?
Sindicic: Most definitely. Number one, in city government, our IT infrastructure continues to grow as people are laid off and departments want to automate more and more processes, which is the right way to go. The IT staff remains the same, but the infrastructure, the data, and the support continues to grow. So I'm trying to implement infrastructure that grows smarter, so we don’t have to work harder, but work smarter, so that we can do a lot more with less.
VMware sure does allow that with centralized control in management, with being able to dynamically update virtual desktops, virtual servers, and the patch management and automation of that. You can take it to whatever level of automation you want or a little in between, so that you can do a little bit of check and balances with your own eyes, before the system goes off and does something itself.
Also, with the high availability and fault tolerance that VMware allows, it's been invaluable. If one of my systems goes down, my VMs automatically will be migrated over, which is a wonderful thing. We’re looking to implement as much virtualization as we can as budget will allow.
Gardner: So fewer of those late night calls? That’s important. It's really been impressive to hear what you’ve been able to do and you are a small-to-medium sized organization and you are on a tight budget. So congratulations on that.
Sindicic: Thank you very much.
Gardner: We’ve been talking about leveraging virtualization and cloud-delivered applications to provide higher levels of service in an increasingly efficient manner especially for core applications.
