AzureVM
Virtual Machines in 'Azure'
Functionality for working with virtual machines (VMs) in Microsoft's 'Azure' cloud: < https://azure.microsoft.com/en-us/services/virtual-machines/>. Includes facilities to create, startup, shutdown, and cleanly delete VMs and VM clusters. With a running VM, execute scripts and install optional extensions. A selection of VM templates based on the 'Data Science Virtual Machine' (DSVM) is supplied; this allows fast and easy provisioning of a VM preinstalled with several software packages useful for data science. Alternatively, users can provide VM templates of their own.
This is a package for interacting with virtual machines in Azure. You can deploy, start up, shut down, run scripts, deallocate and delete VMs from the R command line. A number of VM templates are included based on the Data Science Virtual Machine, but you can also deploy other templates that you supply.
AzureVM uses the tools provided by the AzureRMR package to manage VM resources and templates. The main VM R6 class wraps the deployment template, allowing easy management of all resources as a unit. You can also create a VM in exclusive mode, meaning that it sits in its own resource group.
The package supports both single VMs as well as clusters. A single VM is treated as a cluster containing only one node.
