This document provides an introduction to Cloud Foundry. It discusses why PaaS is useful, describes the key components of Cloud Foundry including the Cloud Controller, Cells, Buildpacks, and Services. It then provides instructions on how to deploy applications to Cloud Foundry including Java applications using Spring Boot or Java EE, as well as applications in other languages. It also covers scaling applications, the use of Organizations and Spaces, logging, and blue/green deployments.
