Cloud computing has grown from a pie-in-the-sky vision to a major IT movement over the past few years. As its promise has grown, though, so too has its scope. This report covers six key sectors in cloud computing: commodity Infrastructure-as-a-Service (IaaS), enterprise IaaS, Platform-as-a-Service (PaaS), Software-as-a-Service (SaaS), cloud storage and private clouds. We highlight the current state of each and provide informed insights into where they — and cloud computing in general — are headed. Much like any market in a still-evolving state, the infrastructure of the cloud-computing transition is still being built by startups, practitioners and even a big-name company or two. Companies mentioned in this report include VMware, Amazon, Nasuni, Terremark and Heroku. For a full list of companies, and to read the full report, sign up for a free trial.
