Uber migrates microservices to multi-cloud platform running Kubernetes and Mesos

(Worked at Lyft) Our number of active micro services was small in comparison. 4,000 is likely a overblown number to highlight the accomplishment possibly counting inactive ones

Does Uber really need 4000 microservices?

A different (better?) question is, does Uber need 4000 API contracts?

The answer to that is probably yes. APIs let us split work across systems/people/teams/regions, and provide a way for both sides of a split to work together. Uber has a lot of teams, a lot of engineers, and so it makes sense that there are a lot of API boundaries to allow them to work together more efficiently. Sometimes those APIs make sense to package as microservices.

How else would engineers demonstrate "impact" for promotions? /s

You jest but also you're not wrong.

Does it matter how they organize their services? Your experience and environment will be different in so many ways that I doubt it's comparable.

Apparently they started at 1000 and went from there...

Maybe they meant instances.

My own company has 800+ microservices. I am very familiar with the politics of microservices.
