Azure Virtual Machines updates, blogs and announcements

• 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 is 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 cannot 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 virtualisation platforms run as native Azure infrastructure as a service (IaaS) VMs and are not 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 parallelisation 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.

• In addition to various Windows Server versions, Azure supports all the major Linux distributions, including Red Hat Enterprise Linux, CentOS, CoreOS, Debian, Oracle Linux, SUSE Linux Enterprise, openSUSE and Ubuntu.

• 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 standardised 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.

• Most Azure VMs come with temporary non-persistent local storage. Additionally, Azure offers HDD and SSD storage for data. Learn more about Azure Disk Storage. Read the technical documentation (for Linux VMs and Windows VMs) to learn about the Azure disks that are available for each VM series.

• 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.

• Of course. Create an Azure free account to learn how Azure works, try products and cloud services and view tutorials on how to deploy your first solution in 10 minutes or less. Get started.

• Security and privacy are built into the Azure platform. Microsoft is committed to the highest levels of trust, transparency, standards conformance and regulatory compliance with the most comprehensive set of compliance offerings of any cloud service provider. Learn more.

• With no upfront cost, you only pay for what you use. Azure provides flexible purchasing and pricing options for all your cloud scenarios, such as the Azure Hybrid Benefit and Azure Reserved Virtual Machine Instances. Azure also offers a comprehensive set of tools to help manage your cloud spend. Learn more.

• More than 95 percent of Fortune 500 companies use Azure. Azure has more global regions than any cloud provider and offers the most comprehensive set of compliance offerings. Azure offers built-in support for the most popular integrated development environments trusted by more than 20 million developers—Visual Studio and Visual Studio Code. Compare Azure vs. AWS.

• On-premises licences for Windows Server 2008 and 2008 R2 Extended Security Updates will end on 14th January, 2023. On-premises licences SQL Server 2008 and 2008 R2 Extended Security Updates will end on 12th July, 2022. Read the complete details.

• Yes, we will offer Extended Security Updates for SQL Server 2012 and Windows Server 2012 and 2012 R2. Free Extended Security Updates will be available for customers on Azure, which includes Azure Virtual Machines, SQL Server on Azure Virtual Machines, Azure Dedicated Host, Azure VMWare Solutions, Azure Nutanix Solution and Azure Stack HCI.
