You Want Modules, Not Microservices

The tweet is obviously wrong.

> I was told ~1200 RPCs independently by several engineers at Twitter, which matches # of microservices. The ex-employee is wrong.

> Same app in US takes ~2 secs to refresh (too long), but ~20 secs in India, due to bad batching/verbose comms.

RPCs are on the server side. Why would they app take longer to refresh in India than in the US?

They might be using cheaper caching in India and dedicate the more expensive ones to areas of the world they get profit from.

An alternative view of this is - Elon isn't a software engineer, so don't listen to him at all.

Yep, this is trivial to falsify, Musk jumped to an incorrect conclusion based on some anecdotes that he did not follow: https://twitter.com/Popeska/status/1592179502838435847

Musk may just be wrong but isn’t it also possible that the RPCs need to communicate with an edge node in India. Perhaps government regulation requires them to store/serve some user data from India if serving Indian customers? Or something like that?
