Troubleshooting Hidden Performance and Costs in Network Traffic Across Multiple AZs with eBPF

Explore techniques for troubleshooting hidden performance issues and costs associated with network traffic across multiple Availability Zones (AZs) using eBPF in this 33-minute conference talk. Learn how spanning Kubernetes clusters across AZs for resiliency introduces challenges in network performance and costs, especially in microservices architectures where a single request can trigger multiple cross-AZ interactions. Discover how Enhanced Berkeley Packet Filter (eBPF) provides unparalleled visibility into the network stack of Kubernetes clusters, helping to uncover concealed performance bottlenecks and understand the nuanced cost implications of cross-AZ network requests. Gain insights from speakers Shahar Azulay from Groundcover and Nirmal Mehta from Amazon Web Services on optimizing multi-AZ Kubernetes deployments for both performance and cost-efficiency.
