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 communicationWhy Layer 7 load balancing offers better traffic management through protocol awareness compared to topology-aware routing's Layer 4 approachHow HAZL (High Availability Zonal Load Balancing) provides a more nuanced solution by balancing cost savings with reliability guarantees through intelligent traffic routingSponsorThis episode is sponsored by Learnk8s — get started on your Kubernetes journey through comprehensive online, in-person or remote training.More infoFind all the links and info for this episode here: https://ku.bz/CBwn51pl-Interested in sponsoring an episode?
