The author is totally right about the HTTP layer/networking stuff. I don't think you have to re-implement SQL transactions, but you do need a backing store that allows acknowledging a message has been processed and not down-sides to processing the same thing twice (idempotent). I did a post about microservices as I've seen them, and I see the more as software evolution matching that of our own biological and social evolution: https://battlepenguin.com/tech/microservices-and-biological-systems/ https://battlepenguin.com/tech/microservices-and-biological-... Like our own immune system, the thousands of moving parts have somehow evolved to fight infections and keep us alive, but it's easy to not be able to understand how any of it really works together.
