Mastering AWS CloudFormation

By: Karen Tovmasyan

Overview of this book

DevOps and the cloud revolution have forced software engineers and operations teams to rethink how to manage infrastructures. With this AWS book, you'll understand how you can use Infrastructure as Code (IaC) to simplify IT operations and manage the modern cloud infrastructure effectively with AWS CloudFormation. This comprehensive guide will help you explore AWS CloudFormation from template structures through to developing complex and reusable infrastructure stacks. You'll then delve into validating templates, deploying stacks, and handling deployment failures. The book will also show you how to leverage AWS CodeBuild and CodePipeline to automate resource delivery and apply continuous integration and continuous delivery (CI/CD) practices to the stack. As you advance, you'll learn how to generate templates on the fly using macros and create resources outside AWS with custom resources. Finally, you'll improve the way you manage the modern cloud in AWS by extending CloudFormation using AWS serverless application model (SAM) and AWS cloud development kit (CDK). By the end of this book, you'll have mastered all the major AWS CloudFormation concepts and be able to simplify infrastructure management.

Continuous Integration and Deployment

We know how to build our templates, and we know how to make sure they are valid and how to deploy them. Now it is time to apply another block of DevOps, called Continuous Delivery (CD). CD is used to test our applications against real-life scenarios and deploy them seamlessly so that the end user notices the changes once they refresh the page. This means no downtime and no The page is under maintenance messages.

In Infrastructure as Code (IaC), you treat your infrastructure and resources as a computer application. Although you cannot perform unit tests against your templates, you still have various options for how to run a proper Continuous Delivery pipeline.

In this chapter, we will learn how to include our templates in our applications. We will also learn how we can test our stacks and how we can apply Amazon Web Services CloudFormation (AWS CloudFormation) in Continuous Delivery practices. By the end of this chapter, we will be able to...
