General purpose virtual machine sizes

General purpose VM sizes provide balanced CPU-to-memory ratio. Ideal for testing and development, small to medium databases, and low to medium traffic web servers. This article provides information about the number of vCPUs, data disks and NICs as well as storage throughput for sizes in this grouping.

  • The DC-series is a family of virtual machines in Azure that can help protect the confidentiality and integrity of your data and code while it’s processed in the public cloud. These machines are backed by the latest generation of 3.7GHz Intel XEON E-2176G Processor with SGX technology. With the Intel Turbo Boost Technology these machines can go up to 4.7GHz. DC series instances enable customers to build secure enclave-based applications to protect their code and data while it’s in use.

  • The Av2-series VMs can be deployed on a variety of hardware types and processors. A-series VMs have CPU performance and memory configurations best suited for entry level workloads like development and test. The size is throttled, based upon the hardware, to offer consistent processor performance for the running instance, regardless of the hardware it is deployed on. To determine the physical hardware on which this size is deployed, query the virtual hardware from within the Virtual Machine.

    Example use cases include development and test servers, low traffic web servers, small to medium databases, proofs-of-concept, and code repositories.

  • Dv2-series, 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. The Dv2-series is about 35% faster than the D-series. Dv2-series runs on the Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors with the Intel Turbo Boost Technology 2.0. The Dv2-series has the same memory and disk configurations as the D-series.

  • The Dv3-series runs on the Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors in a hyper-threaded configuration, providing a better value proposition for most general purpose workloads. Memory has been expanded (from ~3.5 GiB/vCPU to 4 GiB/vCPU) while disk and network limits have been adjusted on a per core basis to align with the move to hyperthreading. 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-series for Windows and Linux.

    Example D-series use cases include enterprise-grade applications, relational databases, in-memory caching, and analytics.

  • The Dav4-series and Dasv4-series are new sizes utilizing AMD’s 2.35Ghz EPYCTM 7452 processor in a multi-threaded configuration with up to 256 GB L3 cache dedicating 8 GB of that L3 cache to every 8 cores increasing customer options for running their general purpose workloads. The Dav4-series and Dasv4-series have the same memory and disk configurations as the D & Dsv3-series.

B-series

Premium Storage: Supported

Premium Storage caching: Not Supported

The B-series burstable VMs are ideal for workloads that do not need the full performance of the CPU continuously, like web servers, small databases and development and test environments. These workloads typically have burstable performance requirements. 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. When the VM has accumulated credit, the VM can burst above the VM’s baseline using up to 100% of the CPU when your application requires the higher CPU performance.

Example use cases include development and test servers, low-traffic web servers, small databases, micro services, servers for proof-of-concepts, build servers.

Size table definitions

  • Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB.

  • Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.

  • Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.

  • If you want to get the best performance for your VMs, you should limit the number of data disks to two disks per vCPU.

  • Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth.

    Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines. To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
