• Visualization: Gain visibility into the status and progress of each stage of the pipeline.
• Orchestration: Sequentially or parallelly orchestrate multiple stages, including source, build, test, and deploy.

2. AWS CodeBuild

Purpose: AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages.

Key Features:

• Build Environments: Supports various build environments and languages.
• Managed Service: Automatically scales to accommodate build workloads.
• Integration: Easily integrates with CodePipeline for automated build and test processes.
• Customizable: Allows custom build scripts and configurations.

3. AWS CodeDeploy

Purpose: AWS CodeDeploy automates application deployments to various compute services, including Amazon EC2 instances, AWS Lambda, and on-premises servers.

Key Features:

• Deployment Strategies: Supports various deployment strategies like rolling, blue/green, and in-place deployments.
• Automated Rollbacks: Automatically rolls back deployments if issues are detected.
• Integration: Integrates with CodePipeline for automated deployments.
• Agent-Based: Uses agents to facilitate deployment on a wide range of targets.

4. AWS CodeCommit

Key Features:

• Git-Compatible: Supports Git commands and workflows.
• Security: Provides fine-grained access control and encryption of repositories.
• Integration: Integrates seamlessly with other AWS DevOps services.
• Collaboration: Supports code collaboration and review with pull requests.

5. AWS CodeStar

Purpose: AWS CodeStar is a fully managed development service that provides a unified experience for building, deploying, and managing applications on AWS.

Key Features:

• Project Templates: Offers project templates for various programming languages and application types.
• CI/CD Pipelines: Automatically sets up CI/CD pipelines using AWS CodePipeline.
• Integration: Integrates with other AWS services for database, storage, and more.
• Team Collaboration: Facilitates team collaboration through integrated collaboration tools.

6. AWS CloudFormation

Purpose: AWS CloudFormation is a service that helps you model and provision AWS infrastructure as code, allowing for consistent and repeatable deployments.

Key Features:

• Infrastructure as Code (IaC): Define and provision AWS resources using templates.
• Version Control: Templates can be stored and versioned in source control systems.
• Automation: Automate the creation and deletion of AWS resources.
• Change Sets: Preview and approve changes before applying them.

7. AWS Elastic Beanstalk

Purpose: AWS Elastic Beanstalk is a Platform as a Service (PaaS) that simplifies the deployment and management of web applications and services.

Key Features:

• Platform Support: Supports various programming languages, containers, and pre-configured runtimes.
• Managed Environment: AWS handles infrastructure provisioning and scaling.
• Integration: Integrates with other AWS services for data storage, monitoring, and more.
• DevOps-Friendly: Allows customization of environments and easy integration with CI/CD pipelines.

8. AWS Lambda

Purpose: AWS Lambda is a serverless computing service that allows you to run code without provisioning or managing servers.

Key Features:

• Event-Driven: Execute functions in response to events (e.g., API Gateway, S3 uploads).
• Auto-Scaling: Automatically scales based on workload.
• Managed Service: No server management required.
• Integration: Easily integrate with other AWS services for data processing and automation.

These AWS DevOps services enable organizations to build scalable, secure, and highly available applications while implementing best practices in CI/CD, infrastructure management, and automation. AWS offers a comprehensive ecosystem to support the entire DevOps lifecycle, from source code management to deployment and monitoring.
