Summary
In this chapter, we covered various tools and techniques that you will need as you increase your infrastructure scale beyond the simple prototypes. By now we should have learned how to limit service access to host's resources, handle the most common pitfalls with ease, run multiple services in a single container, and handle zero-downtime deployments and configuration changes.
In the next chapter, we will spend time working on deploying our own mini version of Platform-as-a-Service (PAAS) using many of the things we have learned so far.
