Service Virtualization - Next Gen Testing Conference Singapore 2013


Published on

Most major enterprises have invested millions of dollars on soIware performance lab infrastructure, that develop recurring maintenance effort and costs, unstable environments, and conflicts over constrained resources. To combat this drain and deliver value, companies need to find ways to optimize. Virtualizing the behavior and performance characteristics of test lab dependencies, CA LISA Service Virtualization has helped many enterprises achieving highly available labs that allow earlier performance testing with greater flexibility, at a much lower cost. Techniques discussed in this session include:

Removing capacity constraints from performance testing lab
Optimizing performance management by decomposing SLAs
Shift-Left: conducting incremental, iterative performance testing
