That brings us to the end of the introduction to Heroku. In this chapter, we built upon on our understanding of cloud computing, the different cloud service models and why cloud-based development makes so much sense in today's business environment. We were introduced to the magical Heroku platform as a service (PaaS), which provides an integrated build, deploy, and operate platform for web developers to deploy and easily manage their apps. We reviewed Heroku's platform architecture and understood the rich feature set of the platform. Finally, we test drove the Heroku platform, touching upon the toolset needed to connect to Heroku and build/deploy a barebones app on Heroku in the process.

In the next chapter, we will delve a little deeper into Heroku's platform architecture and understand how Heroku works under the covers. Specifically, we focus on the details of the Heroku stack, its process architecture, execution framework, and the logging architecture. And there is more—see you there!
