Summary

CoreOS and Docker open up a new era for deploying the services in a cluster to streamline easy development and deployment of applications. CoreOS and Docker bridge the gap between the process of developing a service and deploying the service in production and make the server and service deployment less effort and less intensive work. With lightweight containers, CoreOS provides very good performance and provides an easy way to auto-scale the application with less overhead from the operator side. In this chapter, we have seen the basics of containers, Docker, and the high-level architecture of CoreOS.

In the next few chapters, we are going to see the inpidual building blocks of CoreOS in detail.
