Good post overall.

It seems like this system can only work if the build and deployment is all done by one tool in a monorepo. What does migration from existing setups look like?

And what about services that communicate via shared infrastructure:

- A writes to Kafka topic T

- B reads from Kafka topic T

Ok so we could make the hash of A part of the topic name T, but then on every release we make a new topic and lose history?

Looking forward to future posts.
