Except each service scales independently, can be updated independently (e.g. pri0 security bugs that require a breaking change can be applied to public IP facing services first), can be written in a different programming language, and can be rolled back/deployed independently.

Working in a microservice environment is nice, newly created services get the latest version of whatever tools are needed, older services can be upgraded as needed. Avoids the problem of being stuck on some ancient version of the JVM or Node.
