Blue Ridge Networks needed to test whether AppGuard could handle millions of concurrent users for one of its leading customers, AOL, which was about to commence the distribution of AOL Tech Fortress powered by AppGuard to AOL members. Previous testing revealed AppGuard could handle hundreds of thousands of concurrent users, but the AOL application presented a much bigger challenge—scaling for millions of users.
AOL Tech Fortress, powered by AppGuard, plays a critical role for AOL customers by protecting Windows PCs, laptops and tablets from zero-day malware attacks. “We developed a back-end system that we maintain 24x7 and which interfaces to the AOL back-end for license control and ongoing product service, such as software and configuration updates,” explains Fatih Comlekoglu, a co-founder and the Chief Software Architect for Blue Ridge Networks. “We wanted to test AppGuard to ensure our infrastructure could withstand millions of transactions per day executed by the large volume of AOL customers for software downloads, license activation, and software updates.”
Blue Ridge Networks also wanted to determine whether it would need to scale up its existing server resources or scale out by adding additional servers. In addition, the company needed to validate how dedicated HTTP SSL offload and load distribution worked under various system loads.
“In the past, we relied on our own homegrown scenarios to test each component,” says Comlekoglu. “We already knew our individual components could hold their own, but we were not sure if that would be the case when accessed by millions of website visitors, a scenario for which we could not create realistic simulations.”
