"Gloo is a function gateway built on top of the Envoy Proxy. Gloo provides a unified entry point for access to all services and serverless functions, translating from any interface spoken by a client to any interface spoken by a backend. Gloo aggregates REST APIs and events calls from clients, "glueing" together services in-cluster, out of cluster, across clusters, along with any provider of serverless functions."
