On the outset this abstraction seems very useful for app developers as it's fewer things to talk about, and scaling can become a lot more dynamic when the platforms are given more freedom in placement and auto-scaling of the cluster. However, it also leads to less control as the platform will do a lot of things under the hood.

Instead of sending a message on a message bus with an unclear recipient, send webhooks - simple HTTP GET requests with some payload. In order to increase deliverability safety of this (as you don't want messages to be lost if the receiver is having downtime), you can place a background queue on both the sender and recipient. The sender doesn't send the message directly, instead it places the message on its own queue so it can be retried if the receiver is down. The receiver does not process the message immediately when receiving a message, instead if places the message on its own queue and acknowledges the message to the sender. Now even if the receiver has issues, the message will remain on its own queue until it can be processed successfully and the sender can stop trying to send it. It is very important that these messages remain indempotent, so attach something to the message to allow the receiver to identify the same message again and skip it. This could be a UUID, a version number, or a timestamp depending on the message."

Hemnet must evaluate if the extra complexity makes the stack worse than our own stack and how hard it is to maintain."
