How containers get scheduled in container environments like kubernetes is one of the crucial factors that determine the availability of resources to the applications. This translates to application stability and as an extension, infrastructure costs. A common problem that occurs in such systems is the fragmentation of available resources across nodes. Inadvertently, containers end up getting scheduled in such a way that for any new container, ALL of the resources requested by it are collectively unavailable at any single node, making it un-schedulable. Even though the cluster might have much more overall capacity available across nodes, a scale-up is still needed, which could be simply avoided by carefully re-scheduling the containers across the nodes. In this session, Yash will outline a pod migration strategy derived from games like Jenga and Tetris that carefully relocates pods from current node to a better node, consolidating available resources together to: 1) Fit any new pods stuck waiting for resources, within the existing infrastructure, 2) Avoid such a fragmented scenario by periodically rescheduling pods to keep a healthy balance of different resources requesting applications on each node
Yash is working with Google as Software Engineer, and has 7 years of industrial experience with cloud architectures and micro-service development across Google and VMware. He is been a speaker at multiple international conferences such as Kubernetes Forums and Serverless Practitioners... Read More →
