SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Integrate Envoy Gateway with Istio ambient mesh or Cilium to deliver unified ingress and east-west traffic management, reducing configuration drift and complexity when combining gateways with a service mesh.

Core Features & Use Cases

  • Seamless coexistence of Envoy Gateway with Istio ambient or Cilium, enabling consistent ingress policies and mesh-level routing.
  • Guidance on gateway classes, SecurityPolicy, BackendTLSPolicy, and EnvoyProxy customization to manage trust, TLS termination, and telemetry.
  • Use case: deploy Envoy Gateway as the edge ingress while the mesh handles east-west policy and identity.

Quick Start

Configure Envoy Gateway to run alongside Istio ambient or Cilium, then apply the recommended deployment and policy steps.

FAQPage Schema
How do I integrate Envoy Gateway with Istio ambient mesh for unified traffic management?▼

Integrating Envoy Gateway with Istio ambient mesh involves configuring Gateway API resources, EnvoyProxy customizations, and BackendTLSPolicy for mesh trust. This provides unified ingress and east-west traffic management, reducing configuration drift between the edge gateway and the mesh.

Can I use Envoy Gateway with Cilium service mesh for east-west traffic policy?▼

Yes, Envoy Gateway can coexist with Cilium service mesh to manage east-west traffic policy. By applying SecurityPolicy and aligning observability configurations, the gateway handles edge ingress while Cilium manages mesh-level routing and identity.

What is the best way to configure mTLS participation between Envoy Gateway and a service mesh?▼

Configuring mTLS participation requires applying BackendTLSPolicy for mesh trust or ambient mTLS within your cluster. This ensures secure communication between Envoy Gateway and the Istio ambient or Cilium mesh during east-west traffic routing.

Does Envoy Gateway work with Istio ambient mesh without causing configuration drift?▼

Envoy Gateway works seamlessly with Istio ambient mesh by using shared observability configurations and clear ownership boundaries. This coexistence enables consistent ingress policies and mesh-level routing, specifically reducing configuration complexity and drift.

What are the known limitations of combining Envoy Gateway with Istio or Cilium?▼

Combining Envoy Gateway with Istio or Cilium has known limitations regarding TLS termination, telemetry alignment, and mesh trust policies. Users must follow SafetyPolicy and ownership considerations to navigate these edge cases when deploying the unified ingress architecture.
