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 offerings for general purpose computing.
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, proof-of-concepts, and code repositories.
The A8 – A11 VMs are planned for retirement on 3/2021. For more information, see HPC Migration Guide.
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.
Dav4 and Dasv4-series are new sizes utilizing AMD’s 2.35Ghz EPYCTM 7452 processor in a multi-threaded configuration with up to 256 MB L3 cache dedicating 8 MB 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.
The DCv2-series 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 Intel XEON E-2288G Processor with SGX technology. With the Intel Turbo Boost Technology these machines can go up to 5.0GHz. DCv2 series instances enable customers to build secure enclave-based applications to protect their code and data while it’s in use.
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. The Dv2-series is about 35% faster than the D-series. Dv2-series run on 2nd Generation Intel® Xeon® Platinum 8272CL (Cascade Lake), 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.
Dv3 and Dsv3-series VMs run on 2nd Generation Intel® Xeon® Platinum 8272CL (Cascade Lake), 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 and Esv3-series.
Dv4 and Dsv4-series The Dv4 and Dsv4-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. It features a sustained all core Turbo clock speed of 3.4 GHz.
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. It features a sustained all core Turbo clock speed of 3.4 GHz, Intel® Turbo Boost Technology 2.0, Intel® Hyper-Threading Technology and Intel® Advanced Vector Extensions 512 (Intel® AVX-512). They also support Intel® Deep Learning Boost. These new VM sizes will have 50% larger local storage, as well as better local disk IOPS for both read and write compared to the Dv3/Dsv3 sizes with Gen2 VMs.
