Cloud computing and Virtualization are fundamentally transforming the computer industry. These trends will profoundly change everything from how we develop applications, to the management stacks we use, the way we design datacenters, the way we design computers, and how we deliver end-user computing. In this talk we will describe VMwarees technical approaches to Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Desktop as a Service (DaaS). We will then focus in more depth on our DaaS and IaaS directions, and discuss some of the long term challenges that we are interested in finding solutions for by engaging with the academic research community.
