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.

What is AWS Lambda?

AWS Lambda is a serverless compute service to let you execute your code to do a specialized task. You can upload your code to AWS and define the runtime configuration, CPU and memory requirements, and an event on which your function should be executed. AWS is responsible for booting up servers and required runtime environments to execute the code you provided as soon as the triggering event takes place. You don’t pay for the time AWS takes to provision the servers for you or idle time for the servers when you aren’t using the service; you only pay for the execution time of your code.

AWS Lambda can be triggered from a majority of AWS services and SaaS applications to provide an entry point for your code. Before we go a bit deeper, let’s first understand different concepts related to Lambda to help us understand how it works internally:

  • Function: A Lambda function is an AWS resource that receives an event as a parameter from the invocation...
