Kubernetes at Uber with Lucy Sweet

About this episode

Lucy Sweet discusses Uber's transition to Kubernetes and the challenges faced during the migration.

Guest is Lucy Sweet, a Staff Software engineer at Uber and the lead for the Kubernetes Node Lifecycle Working Group. Imagine trying to move millions of compute cores and thousands of microservices to a brand new platform. All without dropping a single user request, ride, or delivery. Sounds like an absolute logistical nightmare, right? Well, today we are sitting down with someone who actually lived to tell the tale Lucy. In this episode, we are diving deep into Uber's monumental infrastructure journey: moving away from their in-house system to Kubernetes. We'll be unpacking the reality of running at this scale, why it's always DNS and why building things for fun is worth it. Do you have something cool to share? Some questions?
