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.

Summary

In this chapter, we've learned about StackSets, their use cases, how to deploy them, and how to work with failures.

StackSets are a promising feature, although they introduce some complexity, and it is not easy to integrate them with continuous delivery systems. Nevertheless, they come in handy when you want to provision the same stacks across multiple regions or even accounts.

Consider using StackSets when you are tasked to deploy the same environment and resources to your customers—for example, if you provide a B2B SaaS platform or want to automate deployment for development, test, staging, and production environments. StackSets are also useful for replicating your applications across multiple regions if you need to have a point of presence in various countries and continents.

In the next chapter, we will use cfn-init, CloudFormation's helper script, to install software on EC2 resources. Stay tuned!
