Apollo

Starting in 2012, Facebook pioneered an efficient way to build software services in the form of graphs with nodes that connect to one another according to defined schema, and in 2018 it open-sourced GraphQL, the query language that apps can use to interact with graph-based services. Apollo’s GraphOS is a cloud platform that helps hundreds of other companies build and run their own graph-based web and mobile apps. It allows developers to avoid fragile, monolithic archi­tec­tures and instead build services in the form of supergraphs that combine numerous GraphQL-based microser­vices or subgraphs.
