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.
