Building and Delivering Microservices on AWS

Overview of this book

Reliable automation is crucial for any code change going into production. A release pipeline enables you to deliver features for your users efficiently and promptly. AWS CodePipeline, with its powerful integration and automation capabilities of building, testing, and deployment, offers a unique solution to common software delivery issues such as outages during deployment, a lack of standard delivery mechanisms, and challenges faced in creating sustainable pipelines. You’ll begin by developing a Java microservice and using AWS services such as CodeCommit, CodeArtifact, and CodeGuru to manage and review the source code. You’ll then learn to use the AWS CodeBuild service to build code and deploy it to AWS infrastructure and container services using the CodeDeploy service. As you advance, you’ll find out how to provision cloud infrastructure using CloudFormation templates and Terraform. The concluding chapters will show you how to combine all these AWS services to create a reliable and automated CodePipeline for delivering microservices from source code check-in to deployment without any downtime. Finally, you’ll discover how to integrate AWS CodePipeline with third-party services such as Bitbucket, Blazemeter, Snyk, and Jenkins. By the end of this microservices book, you’ll have gained the hands-on skills to build release pipelines for your applications.

Deploying to an EC2 Instance Using CodeDeploy

In this chapter, you will learn about the AWS CodeDeploy service and how this service allows us to automate the software deployment process. We will learn about the service’s benefits and limitations and learn the terminology related to the CodeDeploy service. In this chapter, we will be covering the following topics:

  • What is AWS CodeDeploy?
  • Understanding the application specification file (AppSpec file)
  • Deployment lifecycle events
  • Deployment groups
  • Deployment strategies
  • The CodeDeploy agent
  • Sample app deployment to EC2 instances

In the previous chapters, we developed a microservice using Java, and we generated the artifact for that microservice using the CodeBuild service. In this chapter, we will use the same sample microservice, and try to deploy it to the AWS EC2 instance using the CodeDeploy service. Before discussing the deployment in more detail, we need to understand what the AWS CodeDeploy...
