Enable edge policy management by deploying declarative policy engine, edge policy console, observability integrations, and tracing integrations.

Self-service control and flexibility

Gain fine-grained, self-service control over edge proxy needs and speed up development iterations by eliminating manual tasks and complexity.

Professional world-class support

Access expert support from the Ambassador Labs team behind Edge Stack API Gateway.

How Edge Stack works

Edge Stack Kubernetes-native API Gateway plays an important role throughout the entire microservices lifecycle and can make a difference to your organization's design, development, testing, deployment and observability activities.

Kubernetes ingress controller

Routing user requests into your Kubernetes cluster requires a modern traffic management solution. Edge Stack API Gateway provides a robust Kubernetes Ingress Controller that supports a broad range of protocols, including TCP, HTTP/1/2/3 and gRPC, supports TLS and mTLS termination, and provides reliability and resilience features to protect your backend services.

  • Designed and built with Kubernetes best practices
  • Cross-Origin Resource Sharing (CORS)
  • TLS and mTLS
  • Automatic HTTPS
  • Robust configuration options
  • Enabled for developer self-service

Simplified traffic management

Microservices may crash, but your application shouldn’t. The API Gateway includes support for automatic retries, timeouts, circuit breakers, and rate limiting to maximize application availability. In addition to keeping your application available, the API Gateway supports progressive releases with fine-grained traffic management controls.

Decentralized, declarative workflow

Edge Stack API Gateway empowers development teams to safely manage their ingress, using the same workflow you already use with Kubernetes.

  • Configure using Kubernetes Custom Resource Definitions (CRDs)
  • Operator-focused CRDs, including host, listener, and security configuration
  • Developer-focused CRDs, including mappings and rate limiting configuration
  • Comprehensive protocol support, including TCP, HTTP/1, HTTP/2, HTTP/3, and gRPC and gRPC-Web
  • Zero-downtime reconfiguration
  • Integrate with existing GitOps / Kubernetes workflows
