# AzureVM 2.0.1.9000
|
||||
|
||||
* VM scalesets can now be created with data disks.
|
||||
* Make OS disk type and Linux DSVM data disk type selectable, with a default of "Premium_LRS" for both.
|
||||
* Background process pool functionality moved into AzureRMR; this removes code duplication and makes it available for other packages that can benefit.
|
||||
|
||||
# AzureVM 2.0.1
|
||||
|
||||
* Add methods to retrieve Azure resources used by a VM: `get_disk`, `get_vnet`, `get_nic`, `get_nsg`, `get_public_ip_resource`. These return objects of class `AzureRMR::az_resource`, or `NULL` if not present.

#' Parallelise operations on VM scaleset instances
|

#'
|

#' @param connections The number of concurrent connections to support, which translates into the number of background R processes to create. Each connection requires a separate R process, so limit this is you are low on memory.

|

#' @param ... Other arguments passed on to `parallel::makeCluster`.
|

#'
|
||||
#' @details
|
||||
#' AzureVM can parallelise operations on scaleset instances by utilizing a pool of R processes in the background. This can lead to significant speedups when working with scalesets with high instance counts. The pool is created automatically the first time that it is required, or it can be (re)created by calling `init_pool` manually. It remains persistent for the session or until terminated by `delete_pool`.
|
||||
#'
|
||||
#' If `init_pool` is called and the current pool is smaller than `connections`, it is resized. The size of the pool can be controlled by the global options `azure_vm_minpoolsize` and `azure_vm_maxpoolsize`, which have default values of 2 and 10 respectively. To disable parallel operations, set `options(azure_vm_maxpoolsize=0)`.
|
||||
#'
|
||||
#' Note that the pool size is unrelated to the _scaleset_ size, it only controls how many instances can communicate simultaneously with AzureVM.

AzureVM is a package for interacting with [virtual machines](https://azure.microsoft.com/services/virtual-machines/) and [virtual machine scalesets](https://azure.microsoft.com/services/virtual-machine-scale-sets/) in Azure. You can deploy, start up, shut down, run scripts, deallocate and delete VMs and scalesets from the R command line. It uses the tools provided by the [AzureRMR package](https://github.com/Azure/AzureRMR) to manage VM resources and templates. Version 2.0 of AzureVM is a complete rewrite of the package, aiming to make it a truly generic and flexible interface to VMs.

Working with scaleset instances can be tedious if you have a large scaleset, since R can only connect to one instance at a time. To solve this problem, AzureVM creates a pool of background processes that connect in parallel with the scaleset, leading to significant speedups. The pool is created automatically the first time it is needed, and is deleted at the end of the session.

Parallelise operations on VM scaleset instances
|
||||
}
|
||||
\details{
|
||||
AzureVM can parallelise operations on scaleset instances by utilizing a pool of R processes in the background. This can lead to significant speedups when working with scalesets with high instance counts. The pool is created automatically the first time that it is required, or it can be (re)created by calling \code{init_pool} manually. It remains persistent for the session or until terminated by \code{delete_pool}.
|
||||
|
||||
If \code{init_pool} is called and the current pool is smaller than \code{connections}, it is resized. The size of the pool can be controlled by the global options \code{azure_vm_minpoolsize} and \code{azure_vm_maxpoolsize}, which have default values of 2 and 10 respectively. To disable parallel operations, set \code{options(azure_vm_maxpoolsize=0)}.
|
||||
|
||||
Note that the pool size is unrelated to the \emph{scaleset} size, it only controls how many instances can communicate simultaneously with AzureVM.

Working with scaleset instances can be tedious if you have a large scaleset, since R can only connect to one instance at a time. To solve this problem, AzureVM creates a pool of background processes that connect in parallel with the scaleset, leading to significant speedups. The pool is created automatically the first time it is needed, and is deleted at the end of the session.
