Dagstuhl Seminar 15041: Model-driven Algorithms and Architectures for Self-Aware Computing Systems
Multi-cluster datacenters, and, further, multi-datacenter infrastructure, are supporting increasing amounts and types of computer applications. Among the workloads of these datacenters, business-critical workloads, that is, workloads that support business decision and intelligence, and that provide business and operational back-ends, are increasingly important (over 20% of the general IT load, according to an IDC study from 2010). Our goal is to build self-* resource managers for datacenters supporting business-critical workloads, to ensure efficient operation. We present in this talk new results in characterizing business-critical workloads running in multi-cluster multi-datacenters, and advances in scheduling such workloads using portfolio scheduling, scheduling by guessing (but not predicting) workload characteristics, and scheduling by enabling elasticity even for data-intensive workloads (for example, scheduling for elastic MapReduce frameworks).
