I'm working with a SPA that has a dedicated backend composed of over a dozen microservices.

Each service has its own repo, and its own DB, even though all services are built and maintained by one team.

I do not recommend this.

🚩Can't do atomic commits 🚩Lots of friction jumping between repos and DB's 🚩Hard to configure CI, or to manage cross-repo breaking changes 🚩Repeated code between repos 🚩Hard to maintain data integrity between DBs 🚩Requires many HTTP calls to load a page (there's no BFF) 🚩No easy way to search/navigate between repos 🚩Complex cross-service transactions 🚩Doesn't honor Conway's law
