No, but you can start a business with a singlesystem, keep things well decoupled (hard / software engineer is hard).. Then you gradually run some parts of the systems in different docker containers, then at some point you completely decoupled systems and have different teams handle different service boundaries. You could still have the core system be a big bigger, and sometimes referred to as monolith. But monolith vs microservices is a polarises the discussion, its a gradual scale. Its the engineering, and keeping things separated that matters.
