Why Federated GraphQL?

GraphQL Federation empowers organizations to break down their GraphQL schema into multiple smaller, manageable schemas, each maintained by different teams or services. These individual schemas are then combined into a single, unified graph, ensuring that all teams have consistent access to the data they need. In today's data-driven world, where information is often referred to as the new oil, building a unified API that can be consumed by both internal and external teams is more crucial than ever.

Not all companies start with a federated architecture, Cosmo supports both monolithic and federated architectures.
