This talk will introduce Kinema, an advanced rescheduling system designed to enhance the resource efficiency and cost-effectiveness of Kubernetes (K8s) clusters running in the cloud, particularly during idle periods. The default combination of the cluster autoscaler and the K8s scheduler often leads to underutilization of the cluster due to inaccurate compute node choices based on resource requests rather than actual resource utilization. To address this challenge, Kinema adopts a proactive approach by combining real-time node resource-utilization data from the K8s API, vendor prices per node, and future node resource requirement forecasts. Following this, it uses an internal optimizer with the gathered data as input to calculate the optimal cluster configuration, including node choices and optimal pod placements. Finally, Kinema initiates and monitors a rescheduling iteration using the K8s scheduler to actualize the optimal configuration. This talk concludes with a demo of Kinema.
