Azure uses the following naming convention for its VM sizes: [Family] + [Sub-family]* + [# of vCPUs] + [Additive Features] + [Accelerator Type]* + [Version] Family Indicates the VM Family Series *Sub-family is used for specialized VM differentiations only # of vCPUs denotes the number of vCPUs of the VM These are the first naming standards available when Azure IaaS became Generally Available. When you are resizing a running virtual machine, you might find that many sizes are not available. If you’re coming from a VMWare world, this is quite a change. Figure 1 – Reviewing the numerous Azure VM sizes can be confusing! Each VM size in Azure supports a specific amount of RAM. The Ev3 follows in the footsteps of the high memory VM sizes originating from the D/Dv2 families. Here is a breakdown of the different series of general purpose VMs: Azure’s compute optimized VMs are designed for medium-traffic application servers, web servers or virtual appliances which need a greater ratio of CPU to memory. Different VM families are designed for common use-cases and are comprised of certain amounts of CPU cores and GB of RAM. Virtual Machine Types. There are several ways to run scripts inside an Azure VM, of which the easiest is probably Invoke-AzVMRunCommand in Azure PowerShell. B, Dsv3, Dv3, Dasv4, Dav4, DSv2, Dv2, Av2, DC, DCv2, Dv4, Dsv4, Ddv4, Ddsv4. Av2 / Dv2 / DSv2 / Dv3 / Dsv3-series VMs are designed as entry-level VMs and offer consistent processor performance with different memory capacity and processors. During eight years at Microsoft, he supported multiple teams, including engineering, evangelism, technical marketing, and product planning. These workloads typically have burstable performance requirements. Platform as a service (PaaS), usually gives you the best performance by building apps that run directly in the cloud fabric, but these again may be limited by the APIs available. For more information on how Azure names its VMs, see Azure virtual machine sizes naming conventions. These processors are usually used for graphics, visualizations or compute-intensive artificial intelligence or machine learning applications. It is easy for you to make adjustments with virtualized resources so that you can optimize the size of your VMs for the public cloud. Microsoft offers multiple VM types and sizes for an organization’s needs. It all depends on a large collection of factors. DSv2 / Dv2 / G / GS-series VMs offer a variety of memory options for different ratios of memory to CPU. Find and compare Azure Virtual machines specs and pricing on a one page. If you are unable to use PaaS for the data layer and have to set up a full database server within a VM, then select from the Lsv2 or Ls-series. This can provide significant cost-savings and operational flexibility as you can grow or shrink your VMs alongside your business or seasonal fluctuations. When choosing a VM size, you want to balance price and performance. What VM sizes have worked well for your own workloads? For more information, see HPC Migration Guide. This post, Azure Policy, is the first of a series of posts about Azure Governance. They are recommended for small servers, low-traffic web servers, or development environments. Here is an overview of the memory optimized VMs: For workloads which require high disk throughput and IO, consider selecting a storage-optimized VM. DCv2 series instances enable customers to build secure enclave-based applications to protect their code and data while it’s in use. http://www.SymonPerriman.com [email protected] The B-Series provides these customers the ability to purchase a VM size with a price conscious baseline performance that allows the VM instance to build up credits when the VM is utilizing less than its base performance. See this link for the sizes and how they vary along with prices. Since we only need 64 GiB, the D16S_V3 remains a good starting point. Let’s look at what VM role sizes we have at the moment. Well – this is not a simple question to answer. Sizes. 有关 Azure 如何命名其 VM 的详细信息,请参阅 Azure 虚拟机大小命名约定。 For more information on how Azure names its VMs, see Azure virtual machine sizes naming conventions. Sizes for virtual machines in Azure. The Dv3-series no longer has the high memory VM sizes of the D/Dv2-series, those have been moved to the memory optimized Ev3 and Esv3-series. Improve this answer. Ddv4 and Ddsv4-series The Ddv4 and Ddsv4-series runs on the Intel® Xeon® Platinum 8272CL (Cascade Lake) processors in a hyper-threaded configuration, providing a better value proposition for most general-purpose workloads. DC-series VMs are optimized to securely protect sensitive data and applications using Intel processors with SGX technology. In a nutshell, Azure VM sizes consist of the following series: Series Description A-series Entry-level Economical VMs for Dev/Test D-series General Purpose Compute F-series Compute Optimized Virtual Machines G-series Memory and Storage Optimized Virtual … However, unlike with physical hardware, you are not locked into your selection when you procure it, as it is easy to monitor and adjust the utilization so that you are only paying for the capacity which you need. The Av2-series VMs can be deployed on a variety of hardware types and processors. Dv2 and Dsv2-series VMs, a follow-on to the original D-series, features a more powerful CPU and optimal CPU-to-memory configuration making them suitable for most production workloads. A-series is a basic, cost-effective and economical. VM sizes supported in Azure Stack Hub. Next, you need to decide on whether you will use SaaS, PaaS, IaaS, or some combination of deployment types. These VMs are designed for large databases, warehouses, and big data, and support SQL, NoSQL, Cassandra, MongoDB, Cloudera, Redis and much more. Additional Resources. This means that as we choose a specific VM size, we’re also choosing the associated memory. Here’s how I resized the Azure virtual machine that hosts this site, which started the day as an A2_v2 virtual machine. In most common usage scenarios D3 or D3_v2, and D4 or D4_v2 are the recommended VM sizes on Azure. Not only will this assess your Hyper-V VMs running on Windows Server, but also any VMware VMs managed by vCenter. SaaS, PaaS, IaaS, or some combination of deployment types, General Purpose (Av2, B, DC, Dsv3, Dv3, DSv2, Dv2) – Balanced ratio of CPU and memory, Compute optimized (Fsv2, Fs, F) – High CPU, Memory optimized (Esv3, Ev3, M, GS, G, DSv2, Dv2) – High memory, Storage optimized (Lsv2, Ls) – High disk throughput and IO, GPU (NV, NVv2, NC, NCv2, NCv3, ND, Ndv2) – Specialized workloads for graphics or AI, High performance (H) – These are the fastest (and most expensive) VMs with high CPU and memory for complex computational problems. Ideal for testing and development, small to medium databases, and low to medium traffic web servers. Standard sizes start from A0 to A7 (of these A5 to A7 are considered memory intensive). Microsoft Azure offers six categories of VMs which are optimized for different types of workloads, including: There are many different variations within a category which can make it confusing to pick the right size.
