This case study focuses on the RCA done by Expedia to figure out the reasoning behind delayed requests, connectivity timeouts, then controlling traffic flow, configuring istio for enhanced performance, & migrating the service controller.

Key points
In this session, embark on a comprehensive exploration with us as we:

Delve into how we pinpoint the underlying root cause to be the abrupt termination of worker nodes, during node churn controlled by istio service controller.

Figuring optimal solution catering to our platform involving k8s & aws community collaboration and deciding on the network load balancer IP type service controller utilizing pods as targets instead of nodes.

Mitigate risks by rigorously testing a vast array of scenarios, metricizing uninterrupted traffic flow, and connectivity performance improvement.

Expertly overcome challenges to seamlessly migrate from istio service controller to AWS LB controller in a high-scale production environment ensuring zero downtime.
