I've developed cdk for about 6 months now and it seems to me like a great idea. However, the implementation is quite lackluster. - It's very slow. Deploying our app from scratch takes >30 minues. An update of a single lambda (implementation, not permissions) takes about 3-5 minutes. - Bad error information. On an error, cdk usually just reports which component couldn't be created. Not why it couldn't be created. That information you 'might' find in the aws cloudformation console, or not. - It's buggy. Some deployments randomly fail because cdk couldn't find your cli credentials. Sometimes resources can't be created. In each case it works if you deploy again... I suspect that most shortcomings that I experience are due to cloudformation. I'd really be interested in a 2.0 version that is either highly optimized or polished, or works with a different intermediate abstraction entirely. Updating and validating a tree of resources and policies should not be that difficult, at least not for AWS.
