An Istio Egress gateway is just another envoy instance similar to the Ingress but with the purpose to control outbound traffic. Istio uses ingress and egress gateways to configure load balancers executing at the edge of a service mesh. An ingress gateway allows you to define entry points into the mesh that all incoming traffic flows through. Egress gateway is a symmetrical concept; it defines exit points from the mesh. Egress gateways allow you to apply Istio features, for example, monitoring and route rules, to traffic exiting the mesh.
Istio Observability on Azure Monitor
The purpose of this lab is to explore the current options available to export Istio known observability mechanisms to Azure Monitor, including concerns like:
- Service mesh console
- Centralized Dashboards
- Distributed tracing
