In this chapter, we followed along the history of deployments and looked at how containers with Docker bring us closer to this new world of micro-services. Docker was examined with a high-level overview about which parts we are most interested in. We covered the competition and where Docker fits into the ecosystem with some use cases. Lastly, we also covered when you should - and more importantly, when you shouldn't - consider containers in your infrastructure and development workflow.

In the next chapter, we will finally get our hands dirty and look into how to install and run Docker images along with creating our first Docker image, so be sure to stick around.
