Topology-aware routing: balancing cost savings and reliability, with William Morgan

In this episode, William Morgan, CEO of Buoyant, explores the complex trade-offs between cost optimization and reliability in Kubernetes networking. The discussion focuses on Topology-aware routing and why its implementation might not be the silver bullet for managing cross-zone traffic costs.

William shares practical insights from real-world implementations and explains why understanding these trade-offs is crucial for platform teams managing multi-zone Kubernetes clusters.

You will learn:

• How Topology-aware routing attempts to reduce cross-zone traffic costs but can compromise reliability by limiting inter-zone communication

• Why Layer 7 load balancing offers better traffic management through protocol awareness compared to topology-aware routing's Layer 4 approach

• How HAZL (High Availability Zonal Load Balancing) provides a more nuanced solution by balancing cost savings with reliability guarantees through intelligent traffic routing
