IBM Rational (Green Hat) technology is used by clients who are challenged with testing complex applications. Using Rational technology to virtualise services enables you to do complex testing without deploying a full physical infrastructure.
Implementing the Rational technology can lead to the improved quality of the testing cycle, decreased time to market and satisfied customers using your efficient product.
By virtualising services, clients can performance and integration test much earlier in the delivery life cycle. Instead of at the end where it could impact the schedule and releases. Deployment of virtualised services can be done almost instantaneously, as no administrators are required to grant access and assemble the systems.
Tasks that would have taken months can now be done in hours. Service virtualisation lowers the cost of testing, through the reduction of labour costs, reduction in the time to market and saving on physical infrastructure resources.
