I am super excited about Temporal. I think one of the biggest underacknowledged problems in business software is the way executional details pervade business logic. As soon as your critical logic doesn't simply exist in a request-response logic, it becomes fragmented over queues, scheduled jobs, ETLs, microservices, functions, etc. The actual processes that matter become Rube Goldberg machines that are hard to unders…
It's interesting that you mention workflows and serverless together. In this regard, have you looked at things like AWS Step Functions and Azure Logic Apps? You get the best of both worlds - state machines with excellent workflow management tools along with the flexibility and cost effectiveness of AWS Lambda in the background.
Talking of "Serverless Revolution", I think we are going to see more of such abstractions as things evolve. Abstractions and tools built upon serverless functions that are going to cater more closely to problems being solved rather than worrying about managing new-found complexity of the functions themselves.
