Migrating to Edge Stack

Kubernetes-native API Gateway
What is Ambassador Edge Stack?

Edge Stack, a cloud-native solution, offers advanced API gateway capabilities that empower organizations to unlock the full potential of their microservices architecture and simplifies modern application development and management.

How an Envoy-based API Gateway Can Modernize Your System and Save You Money?

If you are currently using an API gateway based on older or pre-cloud proxy technologies, now is the time to consider migrating to a modern solution to get access to new features, increased performance, and a reduction in resource requirements. Join thousands of organizations that have seen the benefits of migrating to an API Gateway based on Envoy Proxy, the new standard setter for cloud native features and performance. Edge Stack API Gateway is the leading Envoy-based, purpose-built API Gateway.

Ambassador makes it very easy for us to manage endpoints across all our regions worldwide and is able to seamlessly adapt and work with every region’s 80 different endpoints, each with varying configuration requirements.

Key Features of a Cloud Native API Gateway

Envoy Proxy is maintained and developed by a healthy open source ecosystem and a large number of organizations, including Ambassador Labs. Envoy Proxy was initially created by Lyft, with early contributions by leading cloud native companies like IBM, Google, Microsoft, and Red Hat.. This rich base of supporting companies gives the project incredible momentum and means it is always at the cutting edge of features.

Because Edge Stack is based on Envoy, we are the only API gateway that offers support for HTTP/3, and we will continue to stay ahead of the pack in terms of features.

HTTP protocols

All HTTP protocols from HTTP/1 to HTTP/3, WebSockets, gRPC, and raw TCP connections

TLS termination

TLS termination, including automatic certificate provisioning using the ACME protocol and Let’s Encrypt


Routing based on headers, path, host, parameter, and more

Rate limiting

Built-in, advanced rate limit capabilities


Comprehensive, built-in authentication using OAuth or SAML


Monitoring of Rate, Error, and Duration (RED) metrics using Prometheus or compatible systems

Hitless Reloads: Eliminate configuration downtime

Edge Stack can dynamically reconfigure itself without restarting or draining connections, a feature critical in a microservice-based architecture, in which configuration is constantly changing with new deployments and service updates, and where any form of gateway downtime is unacceptable. In gateways based on older proxy technologies this feature has been bolted on as a late addition or is locked behind expensive upgrades.

Decentralized Configuration: Enable platform teams and developers at any scale

Edge Stack routing is configured via Kubernetes Custom Resource Definitions (CRDs) called Mappings. A platform team can manage the shared resources like host names and certificates, while developer teams can dynamically add and remove routing rules specific to their app, removing bottlenecks from the deployment process and increasing your organization’s velocity.

Performance: Enjoy 5x improvements and save costs

Envoy is fast. Incredibly fast. With unencrypted traffic, Edge Stack throughput of Requests Per Second (RPS) is up to 4.5x that of gateways based on older technologies. When the traffic is encrypted, it’s up to _5x_ that of other gateways. That means that not only is your performance ceilinghigher with Edge Stack, but that you can run it with fewer resources, saving critical room in your cloud budget.
