Spanning Kubernetes Clusters across multiple Availability Zones is common when optimizing for resiliency but introduces challenges like network performance and costs when workloads communicate with each other across AZs. AZs are designed for low roundtrip latency between different AZs in the same region, yet in a modern microservices application a single request can trigger multiple interactions crossing an AZ boundary over and over again, through several network layers including Application Load Balancers and Kubernetes proxies. This can create an aggregated effect which is usually hard to detect and troubleshoot on both latency and performance, but also cost since data transfer charges apply for cross-AZ communication. Enhanced Berkeley Packet Filter (eBPF) offers unparalleled visibility into the network stack of a Kubernetes cluster. It can be used to unravel concealed performance bottlenecks and understand the nuanced cost implications of network requests cross AZs in Kuberenetes.
