You don't deliver applications in a vacuum. Applications and the infrastructure that supports them are dynamic systems that change over time. Unrelated system using the same network, servers, and storage can adversely impact application performance. With virtualization, the risk of one virtual server impacting another is quite real. Our End to End Application Performance Management (APM) Tech Center delivers best practices, emerging trends, new products and strategies to help you delivery applications effectively.

BufferBloat And The Collapse Of The Internet

It seems that every few years there's yet another prognosticator that the Internet is about to collapse. Once it was the stellar growth in bandwidth demand driven by the phenomenal increase in Internet-connected devices. At other times, it was the lack of Net neutrality (see this video). Still other times, it was sinister attacks on BGP or the fact that we've run out of IPv4 addresses.

Welcome To The WAN Optimization Shell Game
April 11, 2011 09:30 AM
Posted by David Greenfield
In the early days of Ethernet switch vendors, IT organizations would routinely hear vendors profess to deliver better line rate performance at 20 percent less than the market leader. The catch, because there was always a catch in this industry, was that performance was only achievable in specific circumstances. Turn on port monitoring or enable encryption and Ethernet switch performance would skid to a halt. A similar story may be brewing in the WAN optimization space. While vendors, such as Blue Coat, Riverbed, and Silverpeak, rush to tell us about how they can achieve incredible performance improvement, turning an OC-3 into an OC-12, other limiting factors may prevent end users from actually seeing those numbers.
