Cluster orchestrators manage and monitor workloads that run in large fleets (tens of thousands) of shared compute resources. This talk is a technical deep dive into the challenge of keeping business-critical applications running by implementing preemption. The talk covers the challenges of implementing preemption for heterogeneous workloads, the algorithm Hashicorp designed, and how it is used. Nick and Michael conclude with remaining challenges and future work.
