Question
A company needs a repository that stores source code. The company needs a way to update running software when the code changes. Which combination of AWS services meets these requirements? (Select TWO.)
A. AWS CodeCommit
B. AWS CodeDeploy
C. Amazon DynamoDB
D. Amazon S3
E. Amazon Elastic Container Service (Amazon ECS)
Answer
The correct combination of AWS services to meet the requirements of storing source code and updating running software when the code changes is:
A. AWS CodeCommit
B. AWS CodeDeploy
Explanation
AWS CodeCommit and AWS CodeDeploy are correct because AWS CodeCommit is a service that provides a fully managed source control service that hosts secure Git repositories, and AWS CodeDeploy is a service that automates code deployments to any instance, including Amazon EC2 instances and on-premises servers.
AWS CodeCommit (Option A)
AWS CodeCommit is a fully managed source control service that allows you to securely store and manage your source code in private Git repositories. It eliminates the need to manage your own version control system, making it ideal for collaborative development environments. Key features include:
- Version Control: Enables teams to commit, branch, and merge code efficiently.
- Integration with CI/CD Pipelines: Works seamlessly with other AWS services like CodePipeline and CodeDeploy to automate workflows.
- Scalability and Security: Automatically scales to meet project needs and encrypts data both in transit and at rest using AWS KMS.
AWS CodeDeploy (Option B)
AWS CodeDeploy automates application deployments to various compute platforms, including Amazon EC2, on-premises servers, serverless AWS Lambda functions, and containerized applications on Amazon ECS. It ensures consistent deployments across environments while minimizing downtime. Key benefits include:
- Automated Deployments: Fully automates the deployment process, reducing human error.
- Centralized Control: Provides detailed reports on deployment status and history.
- Integration with Repositories: Pulls application revisions from repositories like AWS CodeCommit or Amazon S3 for deployment.
Why Not the Other Options?
C. Amazon DynamoDB: While DynamoDB is a NoSQL database service, it is not designed for storing source code or managing deployments.
D. Amazon S3: Although S3 can store application artifacts, it lacks version control features crucial for source code management.
E. Amazon ECS: ECS is a container orchestration service, not a repository or deployment tool.
How These Services Work Together
- Developers push their code to an AWS CodeCommit repository.
- Changes in the repository trigger a CI/CD pipeline (e.g., using AWS CodePipeline).
- The pipeline uses AWS CodeDeploy to update running applications automatically on target environments like EC2 instances or Lambda functions.
This combination of services ensures a streamlined DevOps workflow, enabling rapid feature releases while maintaining high availability and reliability. By leveraging AWS CodeCommit for secure source code storage and AWS CodeDeploy for automated updates, companies can efficiently manage their software lifecycle from development to production.
