What Ambassador Edge Stack is

Ambassador Edge Stack is a self-hosted API gateway for routing traffic from a Kubernetes cluster’s edge to its services. It uses Kubernetes for persistence, reliability, availability, and scaling, while Envoy handles routing and proxying. Teams can install it manually or with Helm, and developers can manage service deployments through Kubernetes resources or annotations. Canary deployments let developers set the share of production traffic sent to a service version. The gateway supports HTTP, HTTPS, gRPC, gRPC-Web, HTTP/2, and HTTP/3. Requests can be authenticated through a custom authentication service, OAuth/OpenID Connect, or JWT; a third-party rate limit service can check incoming requests before they are routed. A diagnostics service helps investigate configuration issues, and the gateway can act as an Istio edge proxy for external traffic entering an internal service mesh.

Gravitee federation can import Edge Stack APIs into Gravitee’s control plane. That supports consistent governance and security rules across both sets of APIs, a shared developer portal for discovery, subscription, and testing, and combined analytics across Edge Stack and Gravitee Gateway. The federation agent can run with Docker Compose or be installed with Helm, and requires access to specified Edge Stack resources in the cluster. The product is intended for cloud-native organizations where developers have operational responsibility, as well as developers and operators.

Who it suits

It suits cloud-native teams using Kubernetes that want developers to manage service deployments and control canary traffic. Organizations managing APIs across Edge Stack and Gravitee may also use federation for shared governance, a common portal, and combined analytics.

What it does well

Developers manage deployments through Kubernetes resources or annotations.
Canary controls let developers set traffic shares by service version.
Supports HTTP, HTTPS, HTTP/2, HTTP/3, gRPC, and gRPC-Web.
Offers OAuth/OpenID Connect, JWT, and custom-service authentication.
Federation combines governance, portal access, and analytics across gateways.

What to know first

An Enterprise license is required; licensing information requires contacting the company.
Federation agent requires access to Edge Stack Mappings, Filters, FilterPolicies, and Secrets.

Limits

An Enterprise license is required, and licensing information is available by contacting the company. The page says capabilities are free to explore but does not specify a trial length.

Getting started

Visit the Ambassador Edge Stack website.
Choose a self-hosted deployment and install manually or with Helm.
Contact the company for Enterprise licensing information.
For Gravitee federation, run the agent with Docker Compose or install it with Helm.
Ensure the federation agent has access to the required Edge Stack cluster resources.

Verdict

Choose Ambassador Edge Stack if your cloud-native team needs a self-hosted Kubernetes gateway with developer-managed deployments and traffic controls. Its Gravitee federation can extend governance, portal access, and analytics across gateways. Teams should look elsewhere if they need a published license price rather than pricing on request.
