CDK made IaC accessible to me. I hated raw CloudFormation and never bothered with it because of that reason. I had a crack at Terraform, but never got passed the learning curve before my enthusiasm died.
Currently using some CDK in a production app and finally I found a way of doing IaC I actually enjoy.
You might really like pulumi. I'm kind of on the opposite end, ops>swe so tons of IAC and i'm using pulumi now as I'm more swe focused https://www.pulumi.com/ (ive no relation to them)
Basically exact same as CDK. I really prefer this style over CloudFormation and Terraform. I think Pulumi emerging as another player in the space legitimizes the approach.
CDK is moving quite fast and not all parts are out of the experimental phase, so there are breaking changes shipped often. I think in a couple of years it will stabilize and mature and become a very productive way of working with infrastructure.
