Abstract: An example system including a plurality of computing resources, distributed across a plurality of hosts, to execute virtual workloads; and a computing device, communicatively coupled to the plurality of hosts, comprising a processing resource and a memory resource. The memory resource may store instructions executable by the processing resource to monitor utilization data of the plurality of computing resources executing assigned respective virtual workloads; predict a destination host from the plurality of hosts with available computing resources in an amount to accommodate a predicted resource utilization of a particular virtual workload based on the monitored utilization data of the plurality of computing resources; and migrate the particular virtual workload assigned to a source host of the plurality of hosts to the destination host to be executed.

Abstract: Some examples described herein relate to testing of a cloud service. In an example, a cloud service to be tested may be deployed in a cloud system. A test load may be applied to the cloud service. Upon application of the test load to the cloud service, a determination may be made whether a performance metric related to the cloud service meets a pre-configured criterion. If the performance metric related to the cloud service meets a pre-configured criterion, the cloud service may be scaled. Operations of applying, determining, and scaling may iterated until an end condition is met, wherein the test load applied to the cloud service may vary after each iteration operation.
