It compiles source code, runs tests, and produces software packages that are ready for deployment. As a serverless build service, CodeBuild eliminates the need to provision, manage, and scale your own build servers.
Key features of AWS CodeBuild include:
1. **Fully Managed**: AWS handles all the infrastructure management, including server provisioning, patching, and scaling. You simply provide your build commands and CodeBuild executes them.
2. **Pay-as-you-go Pricing**: You only pay for the compute resources used during your builds, measured in minutes. There are no upfront costs or long-term commitments required.
3. **Scalability**: CodeBuild automatically scales to meet your build volume demands. Multiple builds can run concurrently, reducing wait times for your development teams.
4. **Pre-configured Build Environments**: AWS provides managed images for popular programming languages and frameworks including Java, Python, Node.js, Ruby, Go, Android, and Docker. You can also create custom build environments using Docker images.
5. **Integration with AWS Services**: CodeBuild integrates seamlessly with other AWS developer tools like CodeCommit, CodePipeline, and CodeDeploy to create complete CI/CD pipelines. It also works with third-party tools like GitHub and Bitbucket.
6. **Security**: Build artifacts can be encrypted using AWS Key Management Service (KMS). CodeBuild runs builds in isolated environments, and you can configure VPC settings for accessing private resources.
7. **Build Specifications**: You define your build commands in a buildspec.yml file, which specifies the phases of your build process including install, pre-build, build, and post-build phases.
CodeBuild is ideal for organizations looking to implement continuous integration practices while minimizing operational overhead associated with managing build infrastructure.

What is AWS CodeBuild?
AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready for deployment. It eliminates the need to provision, manage, and scale your own build servers.
Why is AWS CodeBuild Important?
Understanding CodeBuild is essential because it represents AWS's approach to modern DevOps practices. Key benefits include:
• Fully Managed: No servers to provision or manage • Scalable: Automatically scales to meet build volume demands • Pay-as-you-go: You only pay for the build time you use • Secure: Integrates with AWS IAM for access control and can run in your VPC • Flexible: Supports multiple programming languages and build tools
How Does AWS CodeBuild Work?
1. Source Stage: CodeBuild pulls source code from repositories like AWS CodeCommit, GitHub, Bitbucket, or Amazon S3
2. Build Environment: A build environment is created using a Docker container with your specified runtime and tools
3. Build Specification: A buildspec.yml file defines the build commands, phases, and artifacts
4. Build Execution: CodeBuild executes the commands defined in your buildspec file
5. Output: Build artifacts are stored in Amazon S3 or used by downstream services like CodeDeploy
Key Features to Remember:
• Prepackaged build environments for popular languages (Java, Python, Node.js, Ruby, Go, .NET, etc.) • Custom build environments using Docker images • Integration with AWS CodePipeline for CI/CD workflows • Build logs stored in Amazon CloudWatch Logs • Support for local builds for testing
AWS CodeBuild in the Developer Tools Family:
• CodeCommit: Source control (like GitHub) • CodeBuild: Build and test code • CodeDeploy: Deploy applications • CodePipeline: Orchestrates the entire CI/CD workflow
Exam Tips: Answering Questions on AWS CodeBuild
Tip 1: When a question mentions needing to compile code, run tests, or create deployment packages in a managed way, think CodeBuild.
Tip 2: Remember that CodeBuild is serverless - you do not manage any infrastructure. If a question asks about a build service with no server management, CodeBuild is the answer.
Tip 3: Know the difference between CodeBuild and other developer tools. CodeBuild specifically handles the build and test phase, not source control or deployment.
Tip 4: Questions about cost optimization for builds should point to CodeBuild since you only pay for compute time used during builds.
Tip 5: If a scenario describes automating the software release process and mentions building code as part of a pipeline, CodeBuild works with CodePipeline.
Tip 6: Remember the buildspec.yml file - this is where build instructions are defined. Questions may reference configuration files for builds.
Tip 7: CodeBuild can integrate with third-party tools and repositories, making it flexible for existing development workflows.
