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.

Deploying Serverless Applications Using AWS SAM

CloudFormation is a powerful instrument. However, as new technologies and ways of working emerge, new requirements appear for Infrastructure-as-Code (IaC) tools. After the release of Lambda and its integration with other AWS services, including S3, SNS, SQS, and DynamoDB, it appeared that most of CloudFormation's capabilities were not required for serverless development.

So, a Serverless Application Model (SAM) was developed. SAM introduces a different and more simplified way of developing, building, testing, deploying, and operating serverless applications. In this chapter, we are going to learn about SAM and how to use it to facilitate the development of serverless applications.

In this chapter, we will cover the following topics:

  • Introducing AWS SAM
  • Understanding the differences between SAM and CloudFormation
  • Writing your first serverless applications with SAM
