Traffic management
Traffic management is the coordinated control, routing, distribution, or shaping of moving flows through a system.
Google Anthos in Action
Traffic management is the control of how network requests are routed, distributed, delayed, or faulted across service instances and application versions.
- How it is used
- Controls microservice ingress, egress, version routing, progressive migration, and resilience testing within a service mesh.
- How deep it goes
- Explains traffic features and sidecar mechanics, but stops short of detailed configuration commands or troubleshooting procedures.
- Examples
- Uses version-based routing, single-user delivery, gradual migration, HTTP delays, and injected status-code faults as operating examples.
- What you can do after
- Apply it via Istio to route versions, split traffic, expose services, control egress, and test failure responses without application code changes.

Platform Engineering on Kubernetes
Traffic management is the controlled routing and distribution of requests among application versions or service instances.
- How it is used
- Supports safer release strategies by directing selected or copied requests to application canaries.
- How deep it goes
- Explains percentage, header, and mirrored routing, but defers detailed Istio Virtual Service configuration.
- Examples
- Demonstrates a 25% canary weight, 35% mirrored GET traffic, a ten-minute pause, and subsequent mirror-route removal.
- What you can do after
- Apply it via Argo Rollouts and Istio to test canaries with targeted, weighted, or mirrored requests.
