Introduction to Edge Stack API Gateway

Edge Stack is a Kubernetes-native API gateway that delivers scalability, security, and simplicity for some of the world's largest Kubernetes installations.


Simplify to amplify: Solve Kubernetes development challenges throughout the microservices lifecycle

Cloud-native applications are now the gold standard in enterprise IT, driven by demands for scalability, security, and efficiency. According to SlashData, 5.6 million developers — which equates to 31% of all backend developers — have embraced Kubernetes globally. As the uptake of cloud technologies, including Docker and Kubernetes, soars alongside the growth in enterprise developers, a challenge emerges. Development teams keen on swift, secure deployments in a microservices landscape often confront bottlenecks. The hurdles? Organizations and tools that are yet to evolve and align with the revamped life cycle.

Adopting cloud-native development best practices is step one in shipping features and getting applications to market faster. Kubernetes as the de facto container orchestration platform for building cloud-native applications helps deliver speed but also poses new challenges, such as navigating microservice architectures and the complexities and dependencies they create.


Edge Stack: Going big on microservices management

Edge Stack API Gateway is a comprehensive, self-service edge stack. Built on Envoy Proxy and Kubernetes to manage API traffic coming into your Kubernetes cluster, it provides state-of-the-art functionality for observability, availability, security, traffic management, developer onboarding and edge policy management – the critical elements of safe, rapid and frequent application deployment.


With Edge Stack API Gateway, development teams can deploy and iterate rapidly, unhindered by centralized cluster operations or platform team bottlenecks. It empowers application teams to optimize their microservices architecture while retaining the familiar Kubernetes workflow. Furthermore, Edge Stack's intuitive design ensures that development teams can easily manage their routing configurations. By mastering a single Kubernetes resource – the mapping – they can effortlessly channel traffic to their applications.

Integrating Edge Stack

Enhancing every phase of the microservices lifecycle

Edge Stack 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.

Edge Stack core features

Security and authentication at the edge

Secure your microservices and authenticate your traffic:

  • Authentication, including integrations with Okta/Auth0, Keycloak, Google and more
  • Rate limiting, based on IP, user ID or custom identifiers
  • Automatic TLS
  • Comprehensive authentication options (including OAuth2, OIDC, JWT, Single Sign On, etc.)
  • Custom request filters, allowing for dynamic modification requests
  • Web application firewall (WAF)
  • Custom external filters/plugins for additional verification, inspection and logging of requests

Flexible Kubernetes management with Ingress Controller

Route requests into your Kubernetes cluster flexibly while safeguarding reliability and resilience for your backend services:

  • Supports a broad range of protocols, including TCP, HTTP/1/2/3, gRPC and gRPC-Web, TLS and mTLS termination
  • Designed and built with Kubernetes best practices
  • Cross-origin resource sharing (CORS)
  • Powerful configuration options for platform engineers and operations teams, enabling centralized management and global policy specification
  • Designed for developer self-service

Simplified traffic management to ensure high availability

Ensure resilience and uptime for your applications even when microservices crash:

  • Supports automatic retries, timeouts, circuit breakers, and rate limiting to maximize application availability
  • Supports progressive releases with fine-grained traffic management controls, such as advanced load balancing, progressive and continuous delivery support

Decentralized, declarative workflows

Give development teams what they need to safely manage their ingress using the same workflow they already use for 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
  • Zero-downtime reconfiguration
    Integrate with existing GitOps/Kubernetes workflows

Edge policy management

Enable edge policy management:

  • Declarative policy engine
  • Edge Policy Console
  • Observability integrations
  • Tracing integrations

Technical support and assistance

Edge Stack API Gateway subscriptions also come with technical product support and assistance from a team of Support Engineers who are experts on Ambassador Labs products. Our Support Engineers work with users to diagnose and resolve issues and answer questions about product use and behavior.
