Cloud Platforms or PaaS are the next wave of middleware: people are looking at finding complete platforms that can scale from a single instance to running complete enterprise apps as a service. Paul Fremantle will describe what a PaaS is, look at the PaaS offerings available and then dig deep into an Apache-based Open Source PaaS, looking at installation, multi-tenancy, scaling, coding, and more.
