Kubesploit

In this episode, William Morgan, CEO of Buoyant, explores the complex trade-offs between cost optimization and reliability in Kubernetes networking.

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
