Quotas and limits

This document lists the quotas and limits that apply to Cloud Workstations.

A quota restricts how much of a shared Google Cloud resource your Google Cloud project can use, including hardware, software, and network components. Therefore, quotas are a part of a system that does the following:

• Monitors your use or consumption of Google Cloud products and services.
• Restricts your consumption of those resources, for reasons that include ensuring fairness and reducing spikes in usage.
• Maintains configurations that automatically enforce prescribed restrictions.
• Provides a means to request or make changes to the quota.

In most cases, when a quota is exceeded, the system immediately blocks access to the relevant Google resource, and the task that you're trying to perform fails. In most cases, quotas apply to each Google Cloud project and are shared across all applications and IP addresses that use that Google Cloud project.

There are also limits on Cloud Workstations resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.

Limits per region per project

The default Cloud Workstations resource limits per region per project are as follows:

Resource limit	Value
Workstation clusters	3
Workstation configurations	12
Workstations	9000

Additionally, each workstation cluster supports 3,000 concurrently running workstations.

Limits for API requests

The default rate limit for the Cloud Workstations API per project read and write requests is as follows:

Default rate limit	Value
Read requests	180 QPS
Write requests	60 QPS

Quota needed for workstation VMs

For the virtual machines (VMs) that workstations run on, you must allocate the following resources:

• CPU quota
• Persistent Disk quota
• If the VMs have external IP addresses, you need IP address quota

• Sufficient space in your Virtual Private Cloud (VPC) for the internal IP address for the VM

  To use a workstation configuration, make sure that there are sufficient IP addresses available in your VPC. To calculate how many IP addresses need to be available, add these values:

  • Start by adding 1 for each concurrently running workstation that you expect to create using this configuration.
  • If you enabled Quick start workstations, also add the value that you specified for the Quick start pool size.
  • Lastly, add 1 for the IP address used to establish a connection between the Cloud Workstations controller and your VPC.

Request a quota increase

To increase or decrease most quotas, use the Google Cloud console. For more information, see Request a higher quota.
