AWS CodePipeline

I haven't used any other similar products.

CodeCommit and CodeDeploy can be used with CodePipeline so it’s not really fair to stack them against each other as they can be quite the compliment. The same goes for Beanstalk, which is often used as a deployment target in relation to CodePipeline. CodePipeline fulfills the CI/CD duty, where the other services do not focus on that specific function. They are supplements, not replacements. CodePipeline will detect the updated code and handle deploying it to the actual instance via Beanstalk. Jenkins is open source and not a native AWS service, that is its primary differentiator. Jenkins can also be used as a supplement to CodePipeline.

We selected AWS CodePipeline mainly because we wanted to keep the application stack completely native to AWS, and CodePipeline provided the best integrations with AWS services that we were using, such as S3, Elastic Beanstalk, and Lamba. Furthermore, AWS CodePipeline provided the best support for the security paradigms within AWS, such as private subnets and IAM roles. Other services we evaluated would not integrate with these services and security options without a great deal of modification and effort.

I felt that, out of the alternatives, AWS CodePipeline was the simplest to setup and most reliable. Since my client's infrastructure was already hosted in AWS, I felt it was a no-brainer. If a client needed a similar solution with on-prem or non-AWS infrastructure, I would probably evaluate a different solution. AWS CodePipeline is pretty tightly coupled with the rest of the AWS ecosystem.

AWS Codepipeline is proprietary to Amazon Web Services and works well when you're working with other AWS products. If you're using a different technology stack, then Codepipeline may not be the best tool and some open source/closed source tools available on the web may suffice.

We selected CodePipeline again, because it integrates well with our AWS Based infrastructure.

They all pretty much have the same feature set. AWS CodePipeline has been improving in recent years, and it just makes sense to keep everything within Amazon's ecosystem.
