Compute Resources

Allocate CPU and Memory to your backend infrastructure

Compute resources are the fundamental units that represent the processing power and memory available to your projects. The primary compute resources are vCPU and RAM.

This documentation outlines the key aspects of compute resources in the context of the Nhost Cloud Platform.

Shared Compute

In a shared model, compute resources are shared amongst users. This is fine if your services mostly run at low to medium load, occasionally burst for brief periods of time, and can tolerate drops in performance. It is important to understand that the availability of CPU time is not guaranteed.

Free Plan

Projects on the free tier have a total of 2 shared vCPUs and 1 GiB of RAM spread over services as follows:

Service	CPU (MiB)	Memory (GiB)
Postgres	0.5	256
Hasura	0.5	384
Auth	0.5	256
Storage	0.5	128

Pro Plan

Projects on the pro tier have a total of 2 shared vCPUs and 2 GiB of RAM spread over services as follows:

Service	CPU (MiB)	Memory (GiB)
Postgres	0.5	512
Hasura	0.5	768
Auth	0.5	384
Storage	0.5	384

Dedicated Compute

For production workloads where latency is essential or consistent performance is non-negotiable, we strongly suggest the use of dedicated resources.

Compute/Dedicated resources are only available on the Pro plan

To setup dedicated resources for your project, you can either use the Dashboard or the Config.

Config

nhost/nhost.toml

[hasura.resources.compute]
cpu = 500
memory = 1024

[auth.resources.compute]
cpu = 500
memory = 1024

[postgres.resources.compute]
cpu = 500
memory = 1024

[storage.resources.compute]
cpu = 500
memory = 1024

Disk Performance

Services may require a disk provisioned to store data. For instance, postgres comes with a disk provisioned by default and Nhost Run may too. For these cases we provisioned SSD disks with the following performance:

• Baseline: 3000 IOPS
• Baseline: 125Mbps of thoughput
• Every 50GB: +350 IOPS and +15Mbps of throughput

For example, the following disk sizes will have the following performance:

Size	IOPS	Throughput
1	3000	125
10	3000	125
49	3000	125
50	3350	140
100	3700	155
300	5100	215
