Cf intro for spring devs
This document provides an introduction to Cloud Foundry, an open platform as a service (PaaS) that allows developers to deploy and scale applications in seconds without locking themselves into a single cloud. The presentation covers what PaaS is, the benefits of Cloud Foundry including portability and avoiding vendor lock-in, and demos of deploying applications to Cloud Foundry. It also discusses how Cloud Foundry works under the hood and how Spring makes development on Cloud Foundry easy.
