Summary
In this chapter, we started the fine-tuning. First, we learned why we should follow the strategy of managing EC2 Windows instances as ephemeral hosts on Amazon ECS and EKS clusters; then, we learned about custom AMIs and how crucial it is to have an automated custom AMI pipeline, and the benefits of using EC2 Image Builder as a build pipeline. Finally, we covered in great detail why you should use Fast Launch to speed up the EC2 Windows boot startup time.
In the next chapter, we will continue the fine-tuning and learn why it is essential to cache container images on the AMI, and how crucial this is for Windows containers.
