Chapter 12: Automation and Deployment on AWS

So far, you have learned how to configure and deploy various services on AWS. However, most of your configuration has been manual, with very little automation. For example, in Chapter 9, High Availability and Elasticity on AWS, you deployed an application in a multi-tier design. This consisted of application servers configured in an auto-scaling group, an application load balancer, a database to store application data, and an S3 bucket to host your source code. All of this was deployed in a private network in the form of Amazon VPC.

While building your application stack, you had to manually configure the various services on AWS with all the necessary resources to deploy your application. For example, with the VPC, you had to configure subnets, IP address ranges, security groups, NAT gateways, and much more.
