Load testing has traditionally been focused on identification of software or hardware capacity problems, without taking into account the impact of the network on application performance. In many cases applications fail to perform to expected levels, despite load testing prior to roll-out.

Unfortunately, in many cases applications fail to perform to expected levels, despite load testing prior to roll-out. A load test environment that does not reflect all relevant real-world conditions can not provide an accurate projection of how the application will perform once deployed. When this happens, the analysis and decisions leading up to approval to deploy the application may be misguided.

Increasingly, many pre-deployment testing labs have found that it is critical to incorporate the impact of WAN on application load testing. Integrating WAN emulation into load testing has been made easier to accomplish – more than ever before.

But insights drawn from performance testing using remote load generators shows that this method is not valid. Proposed fixes involving the network cannot be tested without making real-world changes to infrastructure. The process for testing deployment can often be complex, requiring significant personnel and resource coordination – can't be done quickly or "on the fly".

Increasingly, many pre-deployment testing labs have found that it is critical to incorporate the impact of WAN emulation with load testing – eliminating the need to set up remote generators. Integrating WAN emulation into load testing has been made easier to accomplish – more than ever before.

For a wide variety of reasons, many applications run poorly when run over a Wide Area Network (WAN). For example, few IT organizations focus on performance during application development or acquisition. That fact, combined with the distributed nature of current application architectures, often results in unacceptable application performance. In addition, initiatives such as the consolidation of servers and data centers, as well as the movement to deploy increasingly distributed application architectures, such as a Services Oriented Architecture, also tend to result in poor application performance.

This Webinar discusses the factors that complicate the task of ensuring acceptable application performance. The webinar also details how WAN emulation can help an IT organization overcome the factors that cause poor application performance.
