istio-traffic-management

Configure Istio routing, load balancing, circuit breakers, and canary deployments for service mesh traffic policies. Comprehensive guide to Istio traffic management for production service mesh deployments. - Covers four core resources: VirtualService for host-based routing, DestinationRule for service-level policies, Gateway for ingress/egress, and ServiceEntry for external services - Includes templates for basic routing, canary deployments (weighted traffic splits), circuit breakers with outlier detection, retries with timeouts, traffic mirroring, and fault injection - Supports multiple load balancing strategies including round-robin, least connections, random, and consistent hashing for sticky sessions - Provides debugging commands via istioctl for analyzing routes, endpoints, and traffic configuration - Configuring service-to-service routing - Implementing canary or blue-green deployments - Setting up circuit breakers and retries - Load balancing configuration - Traffic mirroring for testing - Fault injection for chaos engineering - Start simple - Add complexity incrementally - Use subsets - Version your services clearly - Set timeouts - Always configure reasonable timeouts - Enable retries - But with backoff and limits - Monitor - Use Kiali and Jaeger for visibility - Don't over-retry - Can cause cascading failures - Don't ignore outlier detection - Enable circuit breakers...
