# RUst Service Modules (rusm) rusm is an opinionated paradigm for building service-like rust crates which can be composed together for many of the benefits of Service-oriented Architecture without the significant overhead of separately deployable microservices. rusm lets you build a bundle of modules which can be deployed together in a monolith at first and then pulled apart into individually deployed units if/as it becomes necessary without modifying any service code, letting you move fast while remaining prepared for the future.
