A. 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.
B. 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.
C. 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.
D. 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.
