With more applications being built for the Web, performance testing is critical to determining the proper approach to scaling both applications and infrastructure. But for many years performance testing was largely a rich-man's game, primarily because of the expense of setting and maintaining a large server infrastructure that can simulate real-world traffic.

Hosted testing solutions make a lot of sense from both the user and provider perspective. Considering the vast computing power available at your fingertips there are few reasons why you would want to own the infrastructure, or not take advantage of the latest offerings from providers both large and small.

To that end, Hewlett-Packard is slated on Wednesday to announce LoadRunner in the Cloud, a new application performance testing suite running on Amazon Elastic Compute Cloud (EC2).
