Apollo Federation is an architecture for composing multiple GraphQL services into a single graph that addresses this need. Unlike other approaches such as schema stitching, it is based on a declarative composition programming model that allows proper separation of concerns. This design allows teams to implement an enterprise-scale shared data graph as a set of loosely coupled, separately maintained GraphQL services.
