## AI overview

This article introduces schema services as a transitionary architecture for organizations moving toward a federated GraphQL architecture. It discusses how schema services can help bridge legacy and modern services, mixed protocols, data-centric APIs, and GraphQL skills gaps during an Apollo Federation adoption.

## Source excerpt

The reality for most large organizations adopting Federation is that the architecture sitting behind it is... messy. In this article, I will introduce the concept of schema services and demonstrate how they can provide an easier transition towards a federated architecture. From a jumble of modern and legacy services, different tech stacks, data sources, platforms, etc. most enterprise architecture diagrams look more like a grab bag of tech from the last couple of decades than anything else.
