 By using a Batch extension to Azure CLI, users can run Batch jobs without writing code.
 
 Create and use JSON template files with Azure CLI to create Batch pools, jobs, and tasks. Use CLI extension commands to easily upload job input files to the storage account associated with the Batch account, and download job output files.
