Frequently asked questions about Azure and Azure VMs
Azure Virtual Machines are image service instances that provide on-demand and scalable computing resources with usage-based pricing.
More broadly, a virtual machine behaves like a server: It's a computer within a computer that provides the user the same experience they would have on the host operating system itself. In general, virtual machines are sandboxed from the rest of the system, meaning that the software inside a virtual machine can’t escape or tamper with the underlying server itself.
Each virtual machine provides its own virtual hardware including CPUs, memory, hard drives, network interfaces, and other devices.
A range of guest operating systems, including the Azure-endorsed Linux and Windows Server versions can be migrated to Azure. Migrate physical servers or virtual machines from VMware environments and Microsoft Hyper-V environments with Azure Migrate. VMs migrated from these on-premises virtualization platforms run as native Azure infrastructure as a service (IaaS) VMs and aren't dependent on the on-premises hypervisor.
vCPU stands for virtual central processing unit. A vCPU is a share of a physical CPU that is assigned to a virtual machine. An Azure VM can contain one or more vCPUs.
Some Azure Virtual Machines support hyperthreading. Hyperthreading improves parallelization of computations performed on x86 microprocessors. For each physical processor core, the operating system addresses two virtual cores and shares the workload between them. A list of Azure VMs supporting hyperthreading is available in Azure Virtual Machines documentation.
Azure offers a range of virtual machines—there’s a VM for every workload. View the entire set of Azure Virtual Machine Series or read the documentation for Linux VMs or Windows VMs to learn more.
The concept of Azure Compute Units (ACUs) provides a way of comparing compute (CPU) performance across Azure VM sizes. This helps to easily identify which Azure VM is most likely to satisfy your performance requirements. ACU is currently standardized on a Small (Standard_A1) VM being 100, with higher numbers representing approximately how much faster those products can run a standard benchmark.
There are several Microsoft and partner tools and a large ecosystem of partners to help migrate on-premises VMs to Azure. Visit the Azure migration center to learn more.
Availability sets are logical grouping capabilities to ensure that VM resources placed within them are isolated from each other when they are deployed within an Azure datacenter.
Azure ensures that the VMs you place within availability sets run across multiple physical servers, compute racks, storage units, and network switches.
If a hardware or Azure software failure occurs, only a subset of your VMs will be impacted. Availability sets are an essential capability for building reliable cloud solutions. To provide redundancy to your application, it is recommended that you group two or more virtual machines in an availability set.
Microsoft offers a range of OS-independent SLAs for Azure VMs. Read the SLA for Azure Virtual Machines.
As you transition your workloads to Azure, take advantage of Azure Hybrid Benefit to reuse your existing Windows Server licenses with Software Assurance or Windows Server subscriptions for significant savings. For each license, Azure covers the cost of the OS, while you pay for just the VM compute costs. Additionally, through Azure Hybrid Benefit for Linux, you can use your pre-existing on-premises Red Hat and SUSE software subscriptions on Azure. Learn more.
Virtual Machine Scale Sets help you create and manage a group of load-balanced and autoscaling VMs. Deploy VM scale sets using Azure Resource Manager templates, which support Windows and Linux platform images and custom images and extensions.
