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 learned how to perform an initial bootstrap configuration in a more human-friendly way. We learned about cfn-init,  CloudFormation's native configuration-management tool. We used it to deploy a Hello, World application and we even launched our own LNMP stack and instructed it to report its creation status to us.

Using cfn-init allows template developers to use CloudFormation as a centralized tool to both provision resources and underlying configurations and deploy them. cfn-init can be also used to install and update software as a part of the stack operations.

This is the last chapter in Part 2, Provisioning and Deployment at Scale, and we've done a lot of work here. We are now capable of building production-ready infrastructures with CloudFormation, we can test and validate our stacks, we can apply continuous delivery, and we can deploy our stacks in multiple regions and accounts using StackSets.

We did a lot of work mostly...
