Today’s applications typically involve interactions with numerous applications in house, legacy and external to the company. Simulating these across multiple environments can lead to huge cost savings in your performance testing programs. The bulk of these savings come in the long term once a virtualisation strategy is in place that can be implemented across multiple development lifecycles.
However the benefits are so wide reaching we are seeing them pay for themselves even in short term engagements. These short term savings come from reductions in infrastructure costs as multiple backend systems can be hosted on a single server. Virtualising also means less downtime and increased test windows which leads to increased coverage and quicker completion. Other savings can be realised from license costs, build time, data preparation and software configuration.
The additional work required to setup virtualisation using tools such as Rational Integration Tester is now massively reduced so additional costs are easily outweighed by the savings made.
