What should a DevOps engineer do to meet these requirements?
Create an application in the AWS Amplify console, and connect the CodeCommit repository. Create a feature branch deployment for each of the environments. Connect the Route 53 domain to the application. Activate the automatic creation of subdomains.
Create a single AWS CodePipeline pipeline that uses the CodeCommit repository as a source. Configure the pipeline so that it deploys to different environments based on the changed branch. Create an AWS Lambda function that creates a new subdomain based on the source branch name. Invoke the Lambda function in the deployment workflow.
Create an application in AWS Elastic Beanstalk that uses the CodeCommit repository as a source. Configure Elastic Beanstalk so that it creates a new application environment based on the changed branch. Connect the Route 53 domain to the application. Activate the automatic creation of subdomains.
Create multiple AWS CodePipeline pipelines that use the CodeCommit repository as a source. Configure each pipeline so that it deploys to a specific environment based on the configured branch. Configure an AWS CodeDeploy step in the pipeline to deploy the application components and to create the Route 53 public hosted zone.
Explanations:
AWS Amplify supports the deployment of both frontend and backend code from a CodeCommit repository. Amplify can automatically deploy different branches to different environments, including subdomains based on the branch name. It also integrates with Route 53 for domain management and automatic subdomain creation.
While CodePipeline can be used to deploy to different environments based on branches, creating a Lambda function to manage subdomains in Route 53 is not the most efficient or recommended method. AWS Amplify handles this natively, making this approach unnecessarily complex.
Elastic Beanstalk can handle deployments, but it is not designed for seamless branch-based environment management like Amplify. Additionally, Elastic Beanstalk does not automatically create subdomains for development environments tied to branch names, unlike AWS Amplify.
While multiple CodePipeline pipelines can be used for different environments, AWS CodeDeploy is more suitable for deploying to EC2 instances rather than serverless or fully managed environments. Additionally, CodeDeploy does not automatically handle Route 53 subdomain creation, making this option overly complex and not the best choice.
I plan that the answer is:
Create an application in the AWS Amplify console, and connect the CodeCommit repository. Create a feature branch deployment for each of the environments. Connect the Route 53 domain to the application. Activate the automatic creation of subdomains.
