Istio Gateway
Istio Gateway is a component of the Istio service mesh that provides traffic management, security, and observability for microservices. It acts as an ingress gateway, managing external traffic entering the service mesh and providing advanced routing capabilities.
Key Features
Traffic Management
Advanced routing rules, load balancing, and traffic splitting for canary deployments.
Security
mTLS encryption, authentication, and authorization policies.
Observability
Built-in metrics, distributed tracing, and logging integration.
Kubernetes Native
Designed specifically for Kubernetes environments.
