Introduction to Apollo Federation
Understand the concepts of GraphQL Federation, its benefits for microservice architectures, and how it differs from schema stitching.
Welcome to Federation
Welcome to Apollo Federation! This powerful architecture helps you build a single, unified GraphQL API from multiple independent microservices.
Imagine having many small services, each responsible for a part of your application. Federation lets them all contribute to one big GraphQL schema.
The Microservices Challenge
In a microservices architecture, you often have different teams managing separate backend services. How do you expose a coherent GraphQL API?
- Monolithic GraphQL: One big server, hard to scale for large teams.
- Multiple GraphQL Endpoints: Clients need to query different services, increasing complexity.
Federation offers a clean solution to this challenge.
