Burden to Bliss: Eliminate Patching and Upgrading Toil with Cluster Autoscaler at Scale - Shaikh Israil & John Moore, Oracle America Inc

Tired of patching/upgrading clusters rather working on a feature or finishing up that dashboard you wanted for so long? Running your own cloud native applications in a Kubernetes cluster comes with a lot of operational burden for maintaining the infrastructure. Cluster upgrades and migrating workloads are major pain points that require some of the most planning. Imagine managing this at scale in 30+ regions for a highly available service! With a simple change in the autoscaler, we have minimized this operational overhead to simply doing a single deployment per cluster! Come back a few hours later and voila! it’s all patched/upgraded! This talk will cover sharing our experience on how patching/upgrading the infrastructure at scale became a nightmare as we scaled up to 60+ regions, how we reduced the “devops toil” to keep the lights on, and more importantly, uncover how we did it safely for statefulset applications reducing the downtime drastically.
