VMWare just bought SpringSource. Looks to me like they are going to compete with Google Apps Engine: offer a java based cloud platform as a service.
This is probably good news for everybody who is using the free and open source versions of spring and grails. My thinking is that VMWare will use the free version to get as many developers on board as possible, and then try to convince companies that the best place to run their applications is on VMWare’s servers.
