Many of the IBM software products that fit the nature of cloud computing, but also applications specifically for prototyping or to support proofs of concept, are available in the public image catalog of IBM® SmartCloud® Enterprise.
Take for instance WebSphere® Application Server (WAS), which is often used as part of web-based application stack, which now can be deployed within 30 minutes to test your newly-developed J2EE application. And even better, when using the pay-as-you-go license model, you only pay for the instance and software for the time you actually have it running. This saves a lot of time to create the infrastructure, install, and configure WAS and your J2EE application. This also saves you money because you only pay for the minutes/hours/days you actually need to test your J2EE application.
