Much performance testing is done at a project or application level. Some projects have multiple consumers of their services, such as databases, single-sign on, and Web Services - or are consumers of these kinds of services and have to share them with other projects.
Few organizations plan to effectively test the performance of the system as a whole when a new or upgraded component or sub-system is brought online, to assess the effects of changes or upgrades to components, or how to validate and scale shared components. When problems occur in these shared components, effects can be felt in multiple applications.
Ultimately, no matter how well a sub-system performs in isolation, its performance characteristics will change when it is integrated, and its performance will impact the system as a whole. During this segment, Eric Proegler discusses these challenges, and approaches for ensuring that the performance impact of adding, sharing, or changing a sub-system meets user expectations.
