Plan Names
Every compute plan has a short, structured ID such as ca2c.l or cam2c.2xl. Once you know the
pattern you can read a plan’s processor, family, region, storage tier, and size straight from its
name. No lookup table required.
Since October 11, 2026, plans cover CPU and memory only. The root disk is billed separately per GB. See Instance Types.
Anatomy of a plan ID
Section titled “Anatomy of a plan ID”A plan ID is a series followed by a . and a size:
Memory- and CPU-optimized plans add a family letter, and budget storage tiers add a trailing s
(b2.g2, YUL) or h (b1.g3, YOW):
Segments
Section titled “Segments”| Position | Values | Meaning |
|---|---|---|
| Prefix | c | Compute |
| Processor | i / a | Intel / AMD |
| Family | (none) / m / c | General purpose / Memory-optimized / CPU-optimized |
| Region | 1 / 2 | YOW / YUL |
| Variant | (none) / s / h | Standard tier / Budget tier on b2.g2 (YUL) / Budget tier on b1.g3 (YOW) |
| Compute-only | c after the family and variant | CPU and memory only, root disk billed separately |
| Size | xs s m l xl 2xl 4xl 6xl | Relative capacity, smallest to largest |

vCPU-to-RAM ratios
Section titled “vCPU-to-RAM ratios”The family determines how vCPU and RAM scale together:
| Family | Ratio (RAM:vCPU) | Notes |
|---|---|---|
General purpose xs–l | 2:1 | |
General purpose xl and up | 4:1 | Capped at 16 vCPU |
Memory-optimized (m) | 8:1 | For RAM-heavy workloads |
CPU-optimized (c) | 1:1 | High-density compute |
