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

My personal microservice fiefdom is about ten. My company probably has 1000. Is this ratio normal?

Any more than 1 microservice per engineer (as in, 7 microservices for a 7 engineer team) is too much for engineers to handle during on-call incidents.

If management values business SLAs that is.
