Kubernetes: Zero downtime update while handling one million req per sec
- boulos 11y agoIt's easy to miss this, but the big point is doing a rolling update when running at serious scale: > What is exciting is that while successfully handling 1 million HTTP requests per second with uninterrupted availability, we have Kubernetes perform a zero-downtime rolling upgrade of the service to a new version of the software while we're still serving 1 million requests per second.
