Overview of this book

Continuous integration and continuous delivery (CI/CD) has never been simple, but these days the landscape is more bewildering than ever; its terrain riddled with blind alleys and pitfalls that seem almost designed to trap the less-experienced developer. If you’re determined enough to keep your balance on the cutting edge, this book will help you navigate the landscape with ease. This book will guide you through the most modern ways of building CI/CD pipelines with AWS, taking you step-by-step from the basics right through to the most advanced topics in this domain. The book starts by covering the basics of CI/CD with AWS. Once you’re well-versed with tools such as AWS Codestar, Proton, CodeGuru, App Mesh, SecurityHub, and CloudFormation, you’ll focus on chaos engineering, the latest trend in testing the fault tolerance of your system. Next, you’ll explore the advanced concepts of AIOps and DevSecOps, two highly sought-after skill sets for securing and optimizing your CI/CD systems. All along, you’ll cover the full range of AWS CI/CD features, gaining real-world expertise. By the end of this AWS book, you’ll have the confidence you need to create resilient, secure, and performant CI/CD pipelines using the best techniques and technologies that AWS has to offer.

Experimenting with AWS FIS on multiple EC2 instances with a terminate action

In this section of the chapter, we will first deploy a sample application on EC2 instances, which will be part of the Autoscaling group. There will be a load balancer on top of the EC2 instance to handle the traffic. We will use FIS to terminate the EC2 instance and validate that the application is still accessible and that new EC2 instances are spinning up automatically and will serve the request shortly.

Perform the following steps to implement the experiment using AWS FIS:

  1. Create an IAM role, AmazonSSMRoleForInstanceQuickSetup, and attach the AmazonSSMManagedInstanceCore AWS managed policy. Then, go to the AWS EC2 console and click on Launch configurations in the bottom-left corner. Then, click on Create launch configuration.
