Webinar 5/11: Percona & PlanetScale Present: Introduction to Vitess on Kubernetes for MySQL

During this joint webinar our speakers, Alkin Tezuysal, Technical Expert at Percona and Sugu Sougoumarane, Co-Founder and CTO at PlanetScale, will provide attendees with hands-on experience using Vitess using Kubernetes. They will start by providing a quick overview of Vitess – including key concepts and terminology, and then describe the deployment options for both in Kubernetes.

The hands-on exercises will cover many of the key workflows with running a sharded system:
