In this chapter, we finalized our Jenkins CI solution by adding the Deployment component to it. We made extensive use of the AWS CLI to orchestrate a blue/green deployment process. The resulting pipeline or a collection of such allows us to continuously integrate our application's code changes and build an AMI containing those, which is then deployed to a given environment after certain tests have been passed and criteria met.

The next chapter takes us in a new direction, introducing the topic of monitoring, metrics, and log collection. We will take a look at tools that can help us stay aware of the state of our infrastructure at any given time, visualize performance, and react to issues.
