Traffic Management Module Overview
Traffic Management Advanced Operations provide comprehensive traffic management and service governance capabilities for cloud-native applications. This module enables fine-grained control over service communication through features like traffic passthrough, circuit breakers, canary releases, and global rate limiting. It supports both inbound and outbound traffic management while maintaining high observability and security standards across multi-cluster environments.
Advantages
The core advantages of Traffic Management Advanced Operations are:
-
Flexible Traffic Control
Supports traffic passthrough configuration and bypass mode to optimize service call chains while maintaining governance capabilities. -
Comprehensive Service Governance
Provides circuit breaker policies, load balancing strategies, and connection pool management to ensure service stability under high concurrency. -
Multi-scenario Release Management
Enables manual/automatic canary releases with visual monitoring, supporting blue-green deployments and A/B testing scenarios. -
Hybrid Environment Support
Manages external services through egress gateways and integrates non-mesh services via external service configurations. -
Enhanced Observability
Offers real-time monitoring of access logs, rate limiting effects, and Pod health status through visual dashboards.
Scenarios
The main application scenarios include:
-
Performance Optimization
Use traffic passthrough for middleware services to bypass unnecessary Sidecar processing. -
Rapid Fault Diagnosis
Enable bypass mode to verify if service anomalies are caused by Sidecar proxies. -
Microservice Version Management
Implement canary releases for safe production deployments of new service versions. -
High-concurrency Protection
Configure global rate limiting and circuit breakers to prevent service avalanches. -
Hybrid Architecture Management
Connect traditional services and cloud-native services through external service registration. -
Network Security Control
Isolate abnormal Pods promptly while maintaining normal service operations.
Limitations
- Requires Sidecar injection for full functionality (except external services)
- Canary release cannot coexist with existing service routing configurations
- Pod isolation status resets during deployments/scale operations
- Global rate limiting requires Redis cluster configuration
- Cross-cluster service discovery constraints for canary releases
- Bypass mode requires Kubernetes v1.23+ clusters
- Egress gateway configuration needs regional consistency in multi-cluster scenarios
- Policies don't apply to traffic-passthrough configured services
