Mastering AWS CloudFormation - Second Edition

Overview of this book

The advent of DevOps and the cloud revolution has compelled software engineers and operations teams to rethink how to manage complex infrastructures and build resilient solutions. With this AWS book, you’ll find out how you can use Infrastructure as Code (IaC) to simplify infrastructure operations and manage the modern cloud with AWS CloudFormation. This guide covers AWS CloudFormation comprehensively, from template structures to developing complex and reusable infrastructure stacks. It takes you through template validation, stack deployment, and handling deployment failures. It also demonstrates the use of AWS CodeBuild and CodePipeline for automating resource delivery and implementing continuous integration and continuous delivery (CI/CD) practices. As you advance, you’ll learn how to modularize and unify your template on the fly using macros or by fixating the version using modules. You’ll create resources outside of AWS with custom resources and catalog them with the CloudFormation registry. Finally, you’ll improve the way you manage the modern cloud environment on AWS by extending CloudFormation through the AWS serverless application model (SAM) and the AWS cloud development kit (CDK). By the end of this book, you’ll have mastered key AWS CloudFormation concepts and will be able to extend its capabilities for developing and deploying your own infrastructure.

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 (CD) 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 Business-to-Business (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 (PoP) 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!
