Microsoft Azure Instance Types

Bs-series are economical virtual machines that provide a low-cost option for workloads that typically run at a low to moderate baseline CPU performance, but sometimes need to burst to significantly higher CPU performance when the demand rises. These workloads don’t require the use of the full CPU all the time, but occasionally will need to burst to finish some tasks more quickly. Many applications such as development and test servers, low traffic web servers, small databases, micro services, servers for proof-of-concepts, build servers, and code repositories fit into this model.
Very small temporary storage is included.

The Dav4 and Dasv4 Azure VM-series provide up to 96 vCPUs, 384 GiBs of RAM and 2,400 GiBs of SSD-based temporary storage and feature the AMD EPYC™ 7452 processor.
The "s" variants support "Premium SSD disk storage" and have smaller temporary storage.

The Dads v5-series virtual machines are based on the 3rd Generation AMD EPYCTM 7763v (Milan) processor. This processor's frequency can achieve up to 3.5GHz. The Dads v5 virtual machine sizes feature high performance, large local SSD storage (up to 3,600 GiB) and provide a better value proposition for most general-purpose workloads compared to the prior Das v4 VM generation (e.g., more local SSD capacity and faster local disk IOPS).

The Das v5-series virtual machines are based on the 3rd Generation AMD EPYCTM 7763v (Milan) processor. This processor's frequency can achieve up to 3.5GHz. The Das v5 VM sizes offer a combination of vCPUs and memory able to meet the requirements associated with most production workloads.
The Das v5 virtual machine sizes do not have any temporary storage thus lowering the price of entry.

The Ddv4 series virtual machines are based on the Intel® Xeon® Platinum 8272CL processor. This custom processor runs at a base speed of 2.5Ghz and can achieve up to 3.4Ghz all core turbo frequency. The Ddv4/Ddsv4 virtual machine sizes feature fast, large local SSD storage (up to 2,400 GiB) and are well suited for applications that benefit from low latency, high-speed local storage.

The Ddsv5 series virtual machines are based on the 3rd Generation Intel® Xeon® Platinum 8370C (Ice Lake) processor in a hyper-threaded configuration. The Ddv5 and Ddsv5 virtual machine sizes feature high performance, large local SSD storage (up to 3,600 GiB) and provide a better value proposition for most general-purpose workloads compared to the prior generation (e.g., increased scalability and an upgraded CPU class).

The Dplsv6-series virtual machines are powered by Azure’s first-generation Cobalt 100 processor, delivering outstanding performance for general-purpose workloads. The Azure Cobalt 100 processor operates at 3.4 GHz and provides an entire physical core for each virtual machine vCPU. These virtual machines offer 2 GiB of memory per vCPU and a wide range of vCPU sizes.

The Dplsv5-series and Dpldsv5-series virtual machines are based on the Arm architecture, delivering outstanding price-performance for general-purpose workloads. These virtual machines feature the Ampere® Altra® Arm-based processor operating at 3.0 GHz, which provides an entire physical core for each virtual machine vCPU. These virtual machines offer a range of vCPU sizes, up to 2 GiB of memory per vCPU, and temporary storage options able to meet the requirements of most non-memory-intensive and scale-out workloads such as microservices, small databases, caches, gaming servers, and more.

The Dv5 and Ddv5 series virtual machines feature the 3rd Generation Intel® Xeon® Platinum 8370C (Ice Lake) processor in a hyper-threaded configuration. They can scale up to 96 vCPUs with configurations similar to the Dv4 and Ddv4 series VMs.
They support Azure Premium SSDs and Ultra Disk storage depending on regional availability.

The Eads v5-series virtual machines are based on the 3rd Generation AMD EPYCTM 7763v (Milan) processor. This processor has base frequency of 2.55Ghz and can achieve up to 3.7 GHz. The Eads v5 VM sizes feature up to 672 GiB of RAM, high performance, and large local SSD storage (up to 3,600 GiB.) These virtual machines are ideal for memory-intensive enterprise applications, relational database servers, and in-memory analytics workloads.

The Fsv2-series virtual machines provide 2-GiB of RAM and 8 GB of local temporary storage (SSD) per vCPU(s) and are optimized for compute intensive workloads. The Fsv2-series VMs are hyper-threaded and based on the Intel® Xeon® Platinum 8272CL (second generation Intel® Xeon® Scalable processors), or the Intel Xeon® Platinum 8168 (Skylake) processor.
The Fsv2 VMs can be attached to Premium SSD or Ultra Disk persistent storage.
