The CNCF Technical Oversight Committee (TOC) has voted to accept emissary-ingress as a CNCF incubating project. Emissary-ingress, formerly known as Ambassador, is an open source ingress controller and API Gateway for Kubernetes.

It is built on Envoy Proxy and supports a wide range of use cases for ingress, including load balancing, authentication, and observability.

The project was created at Datawire (now Ambassador Labs) in 2014, and version 1.0 was released in January 2020. It has been adopted by thousands of organizations, many of whom are successfully using it in production, including AppDirect, Lifion by ADP, Ticketmaster, Chick-Fil-A, and OneFootball.

Customers report successfully using emissary-ingress in production with requirements as high as 500,000 requests per second and jumps from 5 million users to 15 million in less than 10 minutes.

Joining CNCF will open emissary-ingress up to more users and contributors. It will also help to advance the north-south use case for Envoy Proxy and help to define best practices for ingress in Kubernetes.
