Microservice Architecture Resources

Hi guys!

I'm searching for good references, best practices and experiences on building Microservice Architecture for large and smaller applications, especially REST (but maybe I'm also interested in gRPC): from the application (self-made API Gateway vs existing solutions on the market), the infrastructure layer (Does a service mesh is still a must-have for smaller app or is there alternatives in the application layer), how to estimate the number of servers required and their characteristics), the database layer (which tool for which Job: logging, storing tokens, transactions, sensitive data etc. putting aside the SQL/NoSQL).

Side note: I'm a Go newbie but I can read Java code too

Many thanks
