Service Mesh Architecture
Implement service mesh with Istio for traffic management, security, and observability.
Service mesh architecture with Istio control plane and Envoy sidecars
A service mesh provides infrastructure-level capabilities for service-to-service communication, including encryption, load balancing, and observability.
Service mesh features:
- mTLS - Automatic encryption between services
- Traffic Management - Routing, retries, circuit breaking
- Observability - Distributed tracing, metrics, access logs
- Policy Enforcement - Authorization and rate limiting
Key Concepts
- Sidecar proxy pattern (Envoy)
- Gradual mesh adoption possible
- Resource overhead considerations
- Integration with external services
- Multi-cluster mesh federation
