In my last job I was a DevOps guy in a Data Eng. team and we used microservice (actually serverless) extensively to the point that none of our ETL relied on servers (they were all serverless; AWS lambda).

Now databases themselves are different stories, they are the persistence/data layer that microservices themselves use . But it's actually doable and I'd even say much easier to use microservices/serverless for ETL because it's easier to develop CI/CD and testing/deployment with non-stateful services. Of course, it does take certain level of engineering maturity and skillsets but I think the end results justify it.

Is there a book or course to buy toward getting an understanding of the more philosophical concepts underneath your approach?
