Mastering AWS CloudFormation - Second Edition

By: Karen Tovmasyan

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.

Writing your first serverless application with AWS SAM

In this section, we will create a few serverless applications to cover most of AWS SAM’s capabilities. The first one—Hello, World—will be created using AWS Quick Start templates, so we can quickly get hands-on experience with AWS SAM.

The second—Party Planner—will be developed from scratch. You don’t have to worry—the actual code is not in the scope of this book and the actual focus will be on creating a complex application with more than one function.

Before we begin development, let’s make sure we have everything we need.

Prerequisites

In order to run the AWS SAM CLI commands, we need to install AWS SAM CLI and its dependencies first. Depending on the OS you have, the steps will be different. The following steps are for installation on macOS.

The guides on how to install AWS SAM CLI on other OSs can be found at https://docs.aws.amazon.com/serverless-application...
