Overview of this book

AWS CodeDeploy, AWS CodeBuild, and CodePipeline are scalable services offered by AWS that automate an application's build and deployment pipeline. In order to deliver tremendous speed and agility, every organization is moving toward automating their entire application pipeline. This book will cover all the AWS services required to automate your deployment to your instances. You'll begin by setting up and using one of the AWS services for automation –CodeCommit. Next, you'll learn how to build a sample Maven and NodeJS application using CodeBuild. After you've built the application, you'll see how to use CodeDeploy to deploy the application in EC2/Auto Scaling. You'll also build a highly scalable and fault tolerant Continuous Integration (CI)/Continuous Deployment (CD) pipeline using some easy-to-follow recipes. Following this, you'll achieve CI/CD for a microservice application and reduce the risk within your software development life cycle globally. You'll also learn to set up an infrastructure using CloudFormation templates and Ansible, and see how to automate AWS resources using AWS Lambda. Finally, you'll learn to automate instances in AWS and automate the deployment lifecycle of applications. By the end of this book, you'll be able to minimize application downtime and implement CI/CD, gaining total control over your software development lifecycle.

Writing an application-specific file

The application file is a YAML, which eliminated the manual intervention of human, after deploying the artifact to the production machine. The AppSpec file will only work with AWS CodeDeploy. Let's try to understand what kind of manual operation done by human is eliminated by the AppSpec.yml file.

Let's say we have a build folder ready to deploy to the production server. While deploying this package or archive, let's say some modification is required in the production server such as relocation of some file, restarting some services, and running some scripts. These things are mentioned in the AppSpec.yml file. That's why the AppSpec.yml file is checked in within the root directory of the application, so once it gets deployed to production server along with the application code, AWS CodeDeploy will start running the AppSpec...
