Abstract

A network-based load testing system provides various functions for managing and conducting load tests remotely using a web browser. The system supports the ability to have multiple, concurrent load testing projects that share processing resources. In one embodiment, the system includes host computers (“hosts”) that reside in one or more geographic locations. Through an administration web site, administrators allocate specific hosts to specific load testing “projects,” and specify how each such host may be used (e.g., as a “load generator” or an “analyzer”). An administrator may also assign users to specific projects, and otherwise control the access rights of each user of the system. Through a user web site, testers reserve hosts within their respective projects for conducting load tests, and create, run, and analyze the results of such load tests. Each project'"'"'s data (scripts, load tests, test results, etc.) is maintained private to members of that project. Attempts to load test unauthorized targets are automatically blocked.
