Apollo Federation is a developer-friendly path to GraphQL microservices for any project, allowing you to elevate your graph from just another API to a platform that exposes the value of your product. Building a graph can feel daunting, but Apollo Federation provides a thin open-sourced specification that makes it possible to modularize your graph into smaller parts using entities and subgraphs. The series aims to help you overcome common challenges devs face when designing, building, and scaling federation in the wild, covering questions such as what is a supergraph and how to deploy a federated graph with proper security for subgraphs. To get started, it's recommended to walk through the getting started guide for Apollo Server and take the Lift-off course in Odyssey, before checking out the posts from the series in order.
