View Azure Batch Parallel Test Execution on the plugin site for more information.
This Jenkins post-build plugin allows you to execute tests in parallel with the Microsoft Azure Batch service, and can reduce the duration of your test runs, and therefore, potentially the cost.
Azure Batch enables you to run parallel applications efficiently in the cloud. It's a platform service that schedules tasks to run on a managed collection of virtual machines. You can find an introduction to the Batch service in the Basics of Azure Batch.
