Azure Virtual Machines (VM) is one of several types of on-demand, scalable computing resources that Azure offers. Typically, you choose a VM when you need more control over the computing environment than the other choices offer. This article gives you information about what you should consider before you create a VM, how you create it, and how you manage it.
An Azure VM gives you the flexibility of virtualization without having to buy and maintain the physical hardware that runs it. However, you still need to maintain the VM by performing tasks, such as configuring, patching, and installing the software that runs on it.
Azure virtual machines can be used in various ways. Some examples are:
Development and test – Azure VMs offer a quick and easy way to create a computer with specific configurations required to code and test an application.
Applications in the cloud – Because demand for your application can fluctuate, it might make economic sense to run it on a VM in Azure. You pay for extra VMs when you need them and shut them down when you don’t.
Extended datacenter – Virtual machines in an Azure virtual network can easily be connected to your organization’s network.
VM size
The size of the VM that you use is determined by the workload that you want to run. The size that you choose then determines factors such as processing power, memory, and storage capacity. Azure offers a wide variety of sizes to support many types of uses.
Azure charges an hourly price based on the VM’s size and operating system. For partial hours, Azure charges only for the minutes used. Storage is priced and charged separately.
VM Limits
Your subscription has default quota limits in place that could impact the deployment of many VMs for your project. The current limit on a per subscription basis is 20 VMs per region. Limits can be raised by filing a support ticket requesting an increase.
