Today we are releasing 7 new general purpose compute VM sizes. In this new version of our A-Series VM’s we have raised the amount of RAM per vCPU from 1.75 GiB or 7 GiB of RAM per vCPU to 2 GiB or 8 GiB per vCPU. We have also improved our local disk random IOPS to be 2-10x faster than that of our existing A version 1 sizes.
These new sizes use our new VM naming schema which is VM family letter followed by the number of vCPU’s of the VM. The ‘m’ identifier after the vCPU count signifies our High Memory offerings (8 GiB/vCPU). (e.g. Standard_A8m_v2)
Size | vCPU | RAM (GiB) | Temporary Disk (SSD) | Max Network Bandwidth |
Standard_A1_v2 | 1 | 2 | 10 GB | Moderate |
Standard_A2_v2 | 2 | 4 | 20 GB | Moderate |
Standard_A4_v2 | 4 | 8 | 40 GB | High |
Standard_A8_v2 | 8 | 16 | 80 GB | High |
Standard_A2m_v2 | 2 | 16 | 20 GB | Moderate |
Standard_A4m_v2 | 4 | 32 | 40 GB | High |
Standard_A8m_v2 | 8 | 64 | 80 GB | High |
With the new VM naming scheme it’s important to realize that the old Standard_A8 is succeeded by the new Standard_H8, not the A8_v2. The new A8_v2 sizes succeed the old A4 and A7. To better understand the mapping of v1 to v2 we have provided the table below.
Comparison: A Standard vs. A_v2
Size | vCPU | RAM (GiB) | Disk Size | Size | vCPU | RAM (GiB) | Disk Size | |
|---|---|---|---|---|---|---|---|---|
A1 | 1 | 1.75 | 20 GB (HDD) | → | A1_v2 | 1 | 2 | 10 GB (SSD) |
A2 | 2 | 3.50 | 70 GB (HDD) | → | A2_v2 | 2 | 4 | 20 GB (SSD) |
A3 | 4 | 7 | 285 GB (HDD) | → | A4_v2 | 4 | 8 | 40 GB (SSD) |
A4 | 8 | 14 | 605 GB (HDD) | → | A8_v2 | 8 | 16 | 80 GB (SSD) |
A5 | 2 | 14 | 135 GB (HDD) | → | A2m_v2 | 2 | 16 | 20 GB (SSD) |
A6 | 4 | 26 | 285 GB (HDD) | → | A4m_v2 | 4 | 32 | 40 GB (SSD) |
| A7 | 8 | 52 | 605 GB (HDD) | → | A8m_v2 | 8 | 64 | 80 GB (SSD) |
