Summary
In this chapter, we covered blue/green deployments, what they are, and how to deploy them successfully. We also talked about the services in AWS that can be used to successfully perform blue/green deployments, along with the processes for performing the deployment with each of the services. Finally, we looked at how to deal with data updates when implementing deployments. We concentrated on which schema changes should be performed first.
In the next chapter, we will begin to look at monitoring and logging for our environments and workloads. This starts with a look at the roles that the CloudWatch and X-Ray services play in DevOps.
