VMs size in Azure
On this page, you’ll understand the available VM sizes. Also, you can use these to run the apps and workloads. Furthermore, it offers deployment considerations to be aware of when you’re planning to use these resources.
| Type | Sizes | Description |
| General purpose | B, Dsv3, Dv3, Dasv4, Dav4, DSv2, Dv2, Av2, DC, DCv2, Dv4, Dsv4, Ddv4, Ddsv4 | Balanced CPU-to-memory ratio. Ideal for testing and development, small to medium databases, and low to medium traffic web servers. |
| Compute optimized | F, Fs, Fsv2 | High CPU-to-memory ratio. Good for medium traffic web servers, network appliances, batch processes, and application servers. |
| Memory optimized | Esv3, Ev3, Easv4, Eav4, Ev4, Esv4, Edv4, Edsv4, Mv2, M, DSv2, Dv2 | High memory-to-CPU ratio. Great for relational database servers, medium to large caches, and in-memory analytics. |
| Storage optimized | Lsv2 | High disk throughput and IO ideal for Big Data, SQL, NoSQL databases, data warehousing and large transactional databases. |
| GPU | NC, NCv2, NCv3, NCasT4_v3 (Preview), ND, NDv2 (Preview), NV, NVv3, NVv4 | Specialized virtual machines targeted for heavy graphic rendering and video editing, as well as model training and inferencing (ND) with deep learning. Available with single or multiple GPUs. |
| High performance compute | HB, HBv2, HC, H | Our fastest and most powerful CPU virtual machines with optional high-throughput network interfaces (RDMA). |
REST API
To gain necessary knowledge using the REST API to query for VM sizes, understand the following:
- First of all, list available virtual machine sizes for resizing
- Secondly, list available virtual machine sizes for a subscription
- Subsequently, list available virtual machine sizes in an availability set
ACU
With ACU you can compare compute performance across Azure SKUs.
Benchmark scores
With benchmark score, compute performance for Linux VMs using the CoreMark benchmark scores.
For more information, compute performance for Windows VMs using the SPECInt benchmark scores.
Manage costs
Azure services necessitate money. Azure Cost Management aids set budgets and configure alerts to keep spending under control. So, analyze, manage and optimize the Azure costs with Cost Management.
