Why that? In a very simple case, all services of a monorepo run on a single VM. Spin up new VM, deploy new code, verify, switch routing. Obviously, this doesn't work with humongous systems, but the idea can be expanded upon: make sure that components only communicate with compatible versions of other components. And don't break the database schema in a backward-incompatible way.
