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.

The deployment infrastructure

The following diagram shows the deployment architecture of the aws-code-pipeline microservice application. We will create a load balancer that will face any HTTP request on port 80, and then route requests to the healthy EC2 instance. We will create two EC2 instances and use the CodeDeploy service to deploy the application to these instances one at a time:

EC2 instances need to have the code deploy agent for the CodeDeploy service to communicate and deploy the application to the instance. EC2 instances also need to assume a role to connect to the S3 bucket to download the application ZIP file instructed by the CodeDeploy service.

We have developed a Terraform template to create the required infrastructure for this chapter. Complete the following steps to create the required infrastructure. We assume that you have the Terraform command line interface (CLI...
