We went through a migration from Ruby on Rails (as a json api) to Go and it just really does make a difference when you need 1/50th the servers to run (don’t remember exact multiple, but it really was that dramatic—the concurrency model enabled so many parallel requests per instance compared to Ruby). It’s kinda like using a map reduce cluster when a beefy server with a few Linus commands piped could have handled the “big data” needs. Both have their time and place, but it’s amazing how far a simple setup can go, so don’t overengineer prematurely.
