Welcome to this lesson on AWS CodeBuild. In this module, we’ll explore how CodeBuild fits into the Build phase of your CI/CD pipeline, automating compilation, testing, and artifact generation. By integrating CodeBuild, you can achieve a fully managed, scalable build process that feeds seamlessly into Continuous Deployment.
The image illustrates a CI/CD pipeline with stages labeled Source, Build, Test, and Deploy, featuring AWS CodeBuild. It includes an infinity loop symbolizing continuous integration and delivery.

​
Why Choose AWS CodeBuild?

AWS CodeBuild is a serverless, fully managed build service that scales with your workload. Key advantages include:
  • Fully managed: No need to provision or maintain build servers.
  • Scalable: Run multiple builds in parallel without limits.
  • Secure: Leverage AWS IAM for permissions and AWS KMS for artifact encryption.
You’re billed only for the compute minutes consumed by your builds, making CodeBuild cost-effective for fluctuating workloads.

Supported Source Repositories

CodeBuild integrates with popular source providers:

Amazon S3https://aws.amazon.com/s3/Store build inputs and outputs
AWS CodeCommithttps://aws.amazon.com/codecommit/Managed Git repositories
GitHubhttps://github.comPublic & private code hosting

​
Integrating or Replacing Jenkins

If you use Jenkins, you can either:
  1. Replace Jenkins entirely with CodeBuild for an all-AWS solution.
  2. Integrate Jenkins and CodeBuild by installing the AWS CodeBuild plugin, offloading build jobs to CodeBuild while maintaining existing pipelines.
