You are required to improve the current deployment process by making it easier to deploy and reduce the time it takes. You need to create a continuous integration (CI) pipeline that can build AMI’s. Your development team will deploy builds less than 5 times a week. Which of the below is the best to get this done?

Answer options:

A.Use a dedicated EC2 instance with an EBS Volume. Download and configure the code and then create an AMI.
B.Use OpsWorks to launch an EBS-backed instance, use a recipe to bootstrap the instance, and then have the CI system use the CreateImage API call to create an AMI.
C.Upload the code and dependencies to Amazon S3, launch an instance, download the package from Amazon S3, and then create the AMI with the CreateSnapshot API call.
D.Have the CI system launch a new instance, bootstrap the code and dependencies on the instance, and create an AMI using the CreateImage API call. Terminate the instance after the build.

Answer – D
Since the number of builds is just a few times a week, there are many open source systems such as Jenkins which can be used as CI-based systems.
Jenkins can be used as an extensible automation server, and Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project.

Option A is incorrect because since you just have less than 5 deployments per week, having a dedicated EC2 instance is not cost-efficient.
Option B is incorrect because having a separate system such as Opswork for such a low number of deployments is not required.
Option C is incorrect because the CreateSnapshot API call does not create AMI but creates an EBS snapshot.
