VMWare is a virtualization software which allows you to create, maintain and administer virtual machines, just like KVM, VirtualBox or Hyper-V. Cloud also includes a third party provider which creates and maintains virtual machines for you. In other words, the notion of the cloud combines virtualization and outsourcing. There are things that companies readily entrust to cloud providers, the largest of which is Amazon.com, but the company databases are usually not among them. I've discussed that numerous times, with some people which were directors and even CIO's and there have always been grave security concerns about entrusting the company's critical business data to the 3rd party. Also, with Oracle, there are licensing considerations. Cloud providers want to do things properly, so everything must be licensed. There are no hide and seek games with the databases, as in the case when the server(s) running VMWare are in your own server room.
Please note that the idea of the virtual machines is much, much older than the cloud itself and that the authorship goes to IBM. IBM virtual machines were all the rage around 1985. The sky was clear then, there were no clouds. Cloud is a modern marketing catchphrase, just like "workgroup" was in the mid-90's. Everything was "workgroup" or, at least, "collaboration edition". IT industry is prone to fads, just like fashion. Not only does the devil wear Prada, it also runs everything in the cloud.
