> queueing between stages

Doesn't it only support a queue depth of 1 at each stage? Last I checked, if you have a change that is queued up waiting to get into a stage, and a newer change comes along, that newer change will supersede the old one. That makes CodePipeline only good for workflows where you only care about deploying the 'newest' of something.

I think the worst thing about CodePipeline is how hard they make it to run custom code from your pipeline. Your options are Lambda (limited to 15 minutes per run, or you have to rewrite your Lambda function to be called once every 30 seconds, essentially using the first run to start your deployment and every subsequent run to check to see if it's done yet or not) or CodePipeline Custom Actions (where you have to write the AWS SDK code for interacting with CodePipeline).

The AWS Developer Tools team could learn a thing or two from Azure Pipelines. They did it "right", IMO: you can create a 'bash' stage in your pipeline which runs whatever script you want from the build agent (which can either be hosted my Microsoft or hosted yourself). That's all I really want. CodePipeline could support that with a custom action but it's more stuff that I would have to set up.
