Server virtualization success quickly set the stage for private-cloud benefits for banking services provider, BancVue. And that cloud enablement then provided business agility to BancVue's community bank customers, enabling them to better compete against mega banks on such critical areas as customer service and end-user portals.

Learn here how BancVue creates the services that empower its customers to beat the giants in their field by better leveraging agile IT. Sunny Nair, Vice President of IT and Systems Operations at BancVue in Austin, Texas, discusses the journey with BriefingsDirect's Dana Gardner, Principal Analyst at Interarbor Solutions. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]

Here are some excerpts:
Gardner: Many companies these days need to tackle the dual task of cutting costs, while also increasing agility and providing better services and response times to their constituents. How did you accomplish both?

Nair: The first thing we wanted to do was to abstract the applications and the operating system from the hardware so that a hardware failure wouldn’t bring down our systems. For that, of course, we went to virtualization. We experimented with various virtualization products. Out of those trials, vSphere was the best software for a heterogeneous environment like ours, where we had Windows and different flavors of Linux.

So we stuck with VMware, and that helped us abstract the hardware layer and our software layer, so we can move our operating systems and our virtual servers to different pieces of hardware, when there was a hardware issue on one server, enabling us to be more agile.

Instead of running just one server on one piece of hardware, we were able to run anywhere between 12 and 20 different servers. All servers weren’t utilized at 100 percent all the time. We were able to leverage the CPU to its full capacity and run many more servers. So we had, at a minimum, a 12x increase in our server capacity on each piece of hardware. That definitely did help our costs.
 Gardner: Tell us a little bit about BancVue.

Marketing expertise

Nair: BancVue is a financial services software and marketing company. We help community financial institutions compete with mega banks by providing them marketing expertise, software expertise, and data consultation expertise, and all those things require technology and software.

For many of our partners we provide the website that many people land on when they search for the website on the Internet. And we also provide the gateway to their online banking. So it's extremely important for the website to stay up and online.

In addition to that, we also provide rewards checking calculations, interest rate calculations, which customer is qualified for certain products, and so on. We are definitely a part of the ecosystem for the financial institution.

Gardner: Once you settled on your strategy for virtualizing your workloads and supporting your heterogeneity issues, how did that unfold?
It was a step-by-step approach of wading deeper into the virtualization world.

Nair: It was a step-by-step approach of wading deeper into the virtualization world. Our first step was just getting that abstraction layer that I was talking about by virtualizing our servers. Then, we looked at it and we said, "Well, from vSphere we can use vMotion and move our virtual servers around. And we can consolidate our storage on a storage-attached network (SAN)." That helped us disengage further from each piece of hardware.

Then, we can look at vCenter Operations Manager and predict when a server is going to run out of capacity. That was one of the areas where we started experimenting, and that proved very fruitful. That experiment was just earlier this year.

Once we did that, we downloaded some trial software with the help of VMware, which is one of the benefits that we found. We didn’t have to pay up immediately. We could see if it suited our needs first.

We used vCloud Director as a trial, and vShield and vCenter Orchestrator together. Once we put all those pieces together, we were able to get the true benefit of virtualization, which is being in a cloud where not only are you abstracted out, but you can also predict when your hardware is going to run out.

You can move to a different data center, if the need happens to be there and just run your server farm like a power utility would run their power station, building out the computing resources necessary for a user or a customer, and then shutting that off when it’s no longer necessary, all within the same hardware grid.

Fit for purpose


Gardner: I suppose it also gets to that point of cutting your total costs, when you can manage that as a fit-for-purpose exercise. It's the Goldilocks approach -- not too much, not too little. That’s especially important, when you have an ecosystem play, where you can’t always predict what your customers are going to be doing or demanding.

Nair: Yes, and that’s true internally as well as externally. We could have our development group ask for a bunch of servers all of a sudden to do some QA, and we've scripted out using the JavaScript system within vCloud Director and vCenter Orchestrator, building machines automatically. We could reduce our cost and our effort in putting those servers online, because we've automated them. Then the vCloud Director could tear them down automatically later.

One admin can do the work of at least three admins, once we’ve fully implemented the cloud, because the buildup and takedown are some of the most expensive portions of creating a server. You can automate that fully and not have to worry about the takedown, because you can say, "Three days from now please remove the server from the grid." Then, the admin can go do some other tasks.
We run Dell hardware, Dell servers, and Dell blades, and that's where we run production. In development, we also use Dell hardware, where we just use the R610s, 710s, and 810s, basically small machines, but with a fairly good amount of power. We can load up to 20 servers on in development, and as many as 12 in production. We run about 275 VMs today.
Cutting-edge technologies

Our production software is software as a service (SaaS), so a majority of that runs on IIS Web servers, with SQL backend. We also use some new cutting-edge database technologies, MongoDB, which also runs on a virtual system.

In addition, we have our infrastructure, like our customer relationship management (CRM), for which we use SugarCRM, and our ticketing system, which is JIRA, and our collaboration tool called Confluence, as well as our build system, which is TeamCity.

All run on VMs. Our infrastructure is powered on VMs, so it’s pretty important that it stays up. It’s one of the reasons that we think running it on a SAN, with the ability to use VMotion, does help our uptime.

A few different things attracted us to VMware. One of them was the fact that VMware fully supported different operating systems. A I said earlier, we run Red Hat, as well as Debian and Windows. When we ran those on different public and other proprietary virtualization products, we found different issues in each one.
We wanted to be able to pick up the phone, ask someone immediately, and get knowledgeable support.

For example, one of them had a time drift, where it didn’t keep time as well as it did on Windows. On Linux the time always seemed to drift a little bit. Apparently they hadn’t mastered that. Some free products did not have the ability to run Windows. They could run other versions of Linux. They couldn't run Windows properly at the time we were testing. But VMware, out of the box, could run all those operating systems.

The second thing was the support level. We didn’t want to be running our production system, put a bug out there in the community, and wait for someone to answer while we were down. We wanted to be able to pick up the phone, ask someone immediately, and get knowledgeable support. So support was a key ingredient in our selection.

We do have that option today when we have an issue. We can call up VMware and get that support. So it was support, compatibility, and the overall ecosystem. We knew that as we grew, we wouldn’t have to switch to another vendor to get cloud. We knew that we could go to VMware and get the cloud solution, as well as the virtualization solution, because virtualization was just the first step to us to become fully virtualized in a private cloud environment, with software, security like vShield and vCenter Operations Manager.

Virtualization lab

We actually had a little virtualization lab, where we practiced these things, because as the old adage says, practice does make perfect. The next thing was that we rolled it out in incremental steps to one product, and then eventually to a larger development group.

Gardner: Looking to the future, is there anything about mobile support or increasing the types of services that you're going to provide to your community banks, more along the lines of extended services that you provide and they brand? Do you think that this cloud environment is going to enable you to pursue that?

Nair: Yes, we’ve already started down that path. We have mobile support for the websites that we’ve created, and we’ve just implemented that earlier this year. Eventually, we plan to go into the online banking space and provide online banking for mobile devices. All that will be done in our cloud infrastructure. So yes, it’s here to stay.

We want to look further at the automation that the cloud products would give us, especially with security in vShield. It’s pretty interesting how we can have a virtual firewall with our VMs and look at the other mobile software that's available.
