Ambassador API Gateway 
Emissary Ingress (formerly known as the Ambassador API Gateway) is an open-source Kubernetes-native API Gateway + Layer 7 load balancer + Kubernetes Ingress built on Envoy Proxy. Emissary Ingress is an CNCF incubation project.
The Ambassador Edge Stack is a complete superset of the OSS Emissary Ingress project that offers additional functionality. Edge Stack is designed to easily expose, secure, and manage traffic to your Kubernetes microservices of any type. Edge Stack was built around the ideas of self-service (enabling GitOps-style management) and comprehensiveness (so it works with your situations and technology solutions).
Emissary Ingress enables its users to:
- Manage ingress traffic with load balancing, protocol support(gRPC and HTTP/2, TCP, and web sockets), and Kubernetes integration
- Manage changes to routing with an easy to use declarative policy engine and self-service configuration, via Kubernetes CRDs or annotations
- Secure microservices with authentication, rate limiting, TLS, automatic HTTPS, and custom request fiters
- Ensure high availability with sticky sessions, rate limiting, and circuit breaking
- Leverage observability with integrations with Grafana, Prometheus, and Datadog, and comprehensive metrics support
- Set up shared development environments with Service Preview
- Onboard developers with a Developer Portal
- Enable progressive delivery with canary releases
- Connect service meshes including Consul, Linkerd, and Istio
- Knative serverless integration

Architecture
Ambassador deploys the Envoy Proxy for L7 traffic management. Configuration of Ambassador is via Kubernetes annotations. Ambassador relies on Kubernetes for scaling and resilience. For more on Ambassador's architecture and motivation, read this blog post.
Getting Started
You can get Ambassador up and running in just three steps. Follow the instructions here: https://www.getambassador.io/docs/edge-stack/latest/tutorials/getting-started/.
If you are looking for a Kubernetes ingress controller, Ambassador provides a superset of the functionality of a typical ingress controller. (It does the traditional routing, and layers on a raft of configuration options.) This blog post covers Kubernetes ingress.
For other common questions, view this FAQ page.
You can also use Helm to install Ambassador. For more information, see the instructions in the Helm installation documentation.
