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.

Creating the launch configuration and Auto Scaling group

Auto Scaling is an AWS Service, which allows us to scale up (adding EC2 instance) or scale down (destroying EC instance) infrastructure automatically in a horizontal manner. Scaling up or scaling down of EC2 instance depends on some policy metrics such as CPU Utilization, health status checks.

AWS Auto Scaling service launches the EC2 instance with the help of the launch configuration. It basically includes the template in which we will mention which AMI, instance type, network configuration, user-data script, and many more, will be used to launch the instance.

Getting ready

To create a launch configuration, we need to create a custom AMI, which should have an application...
