I’ve enjoyed the CDK. I looked at Pulumi, but settled on CDK because it’s AWS developed. As where I work is an AWS shop, I didn’t see many advantages to Pulumi, and I felt more confident in AWS continuing development and support, vs another 3rd party company that could go out of business.

Also I really have enjoyed the built in unit test tooling of the CDK. Unit testing my infrastructure code has been a game changer.
