I don't understand why CodeBuild/CodePipeline is so bad when SWF or Step should make these relatively straightforward to implement...

What’s “bad” about CodeBuild? Its basically just a yml file with bash commands and a section to specify artifacts.

Step function has been a big leap backwards from SWF; which is harder to find. Adding support for more connections to other services on an already broken platform is a disaster.

Step use SWF under the hood. When step was released, it still peeves me that you couldn't edit a function without deleting and recreating; even then, deleting took hours...

Lambda seems pretty reasonably priced, but Step Function transitions seem absurdly expensive to me. Who is actually using Step Functions?

I use them to orchestrated processes that take longer than 15 minutes.

As far as cost, an edict came down from on high not to use any more EC2 instances for custom jobs without a very good reason. We are much more concerned about reducing the amount of time we deal with servers (and the dependence on hiring people to do it) than we are with infrastructure costs.

We use them a ton for long running jobs that require polling before moving to the next job. Mainly use them to run Glue/Batch jobs via lambda, after this week no longer need lambda to start a Glue Job, they can be called directly.
