Your team has developed an application that makes use of AWS resources. In order to provide frequent releases to the customer, you are required to automate the CI/CD process. Which of the following can be used for this purpose?

Answer options:

A.Create a pipeline using AWS Code deploy. Configure a stage for Unit testing as well in the pipeline.
B.Use AWS CodeCommit to host your code repository. Use the build tool in AWS CodeCommit to build your pipeline.
C.Create a Pipeline in the AWS CodeBuild Service.
D.Create a pipeline using AWS CodePipeline along with AWS Code Star service.

Answer – D
Automated continuous delivery pipeline
AWS CodeStar accelerates software release with the help of AWS CodePipeline, a continuous integration and continuous delivery (CI/CD) service. Each project comes pre-configured with an automated pipeline that continuously builds, tests, and deploys your code with each commit.
Option A is incorrect because pipelines are created using the "AWS Code pipeline" and "AWS Code deploy" automates software deployments to a variety of compute services such as Amazon EC2, AWS Fargate, AWS Lambda, and your on-premises servers.
Option B is incorrect since AWS CodeCommit does not have the facility to carry out the build.
Options C is incorrect since the CodePipeline service is used for building build pipelines.

Creating a pipeline in the Code pipeline is not enough to automate the release process you need to integrate with code commit,
Code build and then deploy your code through Cloudformation/Elastic Beanstalk etc.
Whereas in Code star Each project comes pre-configured with an automated pipeline that continuously builds, tests, and deploys your code with each commit.
