Abstract: Examples provided herein describe a method for reducing recovery time for an application. For example, a first physical processor of a computing device may monitor, based on a first application instance of the application running in a first mode, for failure detection of the first application instance running on a first computing device. The first physical processor may determine that the first application instance is to be changed from the first mode to a second mode. Based on the determination, the first physical processor may validate that a second application instance can run in the first mode by performing a data integrity compliance check. Responsive to validating that the second application instance can run in the first mode, the first physical processor may facilitate running of the second application instance in the first mode.

Abstract: Example techniques for relocation of workloads across data centers of a data center system are described. A target for the data center system for power cost reduction or carbon footprint reduction or both is received. Power source information pertaining to power sources that power data centers of the data center system is also received. A workload to be relocated is identified based on characteristics of the workload, the power source information, and the target.

Abstract: Examples disclosed herein relate performing a disaster recovery rehearsal of a workload in a three-datacenter topology. A workload may be selected on a computing system at a first datacenter location of a three-datacenter topology, for performing a disaster recovery rehearsal. The three-datacenter topology may comprise a first datacenter location, a second datacenter location and a third datacenter location. At least one of second datacenter location or third datacenter location may be selected for performing the disaster recovery rehearsal. A configuration of the workload may be cloned to generate a cloned workload. A resource may be identified in a selected datacenter location for performing the disaster recovery rehearsal. The cloned workload may be applied to the resource in the selected datacenter location, and a result of running the cloned workload on the resource may be generated. The computing system may receive the result from the selected datacenter location.
