Challenge: Needed to isolate performance issues in a complex architecture

Spencer Schwab, Staff Application Engineer at Citrix Systems, was responsible for the functionality of the company's core applications—gotomeeting.com, gotowebinar.com, gototraining.com—and made sure they were up all the time, available to customers and had enough capacity. “The biggest challenge of keeping gotomeeting.com up all the time, along with anything else we're running, is trying to find out really where the problems are,” said Schwab. “Getting visibility into what's wrong is hard because everything is really complex. So I've been spending a lot of time troubleshooting some specific problems in production.” Citrix knew there had to be a better way of pinpointing performance issues and getting visibility into its complex architecture.

AppDynamics increased visibility with minimal overhead

Citrix began evaluating application performance management (APM) solutions. “So in the beginning after I set up the AppDynamics platform, it looked really good. I liked a lot of things about it,” said Schwab. “There were other companies that looked really good, too. So we brought them in and did an evaluation.” Citrix found that other solutions hindered system performance rather than enhanced it and couldn't deploy them in production. “Some of the other competitors we were looking at would crash our servers,” said Schwab. “We couldn't even get them in production because our servers would crash in test. With the AppDynamics solution that wasn't the case.” He added, “When our resources got really heavy and the AppDynamics platform was running, it actually has backup algorithms that kept it from crashing our servers.” The AppDynamics solution's production-ready, low-overhead architecture proved to be a good fit for Citrix, making it the clear choice. Once deployed, the platform began to deliver immediate value. “Everything just fell together,” said Schwab. “The ease of implementation, the maintenance, the value you get right out of the box is just amazing.”

“I have a big vision for what the AppDynamics platform can do for our business. It can honestly help us scale and focus on what we need to focus on, what's right for our customers, for our code.”
