Plan Names

Every compute plan has a short, structured ID such as ca2.l or cam2.2xl. 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.

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 (Premium SSD, YUL) or h (HDD, YOW):

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 / Premium SSD budget (YUL) / HDD budget (YOW)
Size	`xs` `s` `m` `l` `xl` `2xl` `4xl` `6xl`	Relative capacity, smallest to largest

Plan series

Series	Region	Processor	Storage	Family
`ci1`	YOW	Intel	NVMe	General purpose
`ci1h`	YOW	Intel	HDD	General purpose (budget)
`ca1`	YOW	AMD	NVMe	General purpose
`ca1h`	YOW	AMD	HDD	General purpose (budget)
`ca2`	YUL	AMD	Pro NVMe	General purpose
`ca2s`	YUL	AMD	Premium SSD	General purpose (budget)
`cim1`	YOW	Intel	NVMe	Memory-optimized
`cim1h`	YOW	Intel	HDD	Memory-optimized (budget)
`cam1`	YOW	AMD	NVMe	Memory-optimized
`cam2`	YUL	AMD	Pro NVMe	Memory-optimized
`cam2s`	YUL	AMD	Premium SSD	Memory-optimized (budget)
`cac1`	YOW	AMD	NVMe	CPU-optimized
`cac2`	YUL	AMD	Pro NVMe	CPU-optimized
`cac2s`	YUL	AMD	Premium SSD	CPU-optimized (budget)

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
