Quotas and limits

This document lists the quotas and limits that apply to Colab Enterprise.

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 Colab Enterprise resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.

Compute Engine quotas

Colab Enterprise runtimes use Compute Engine quotas, including quotas for virtual machine (VM) instances, disks, CPUs, and GPUs. For more information, see the Compute Engine Allocation quotas page.

Vertex AI request quotas

Colab Enterprise runtime and runtime template requests count toward Vertex AI quotas. The relevant Vertex AI quotas include the following:

Vertex AI quota Colab Enterprise interaction Limit
Resource management requests Runtime and runtime template requests 600/minute
Job or long-running operation requests per minute Runtime and runtime template requests 60/minute

Dataform request quotas

Colab Enterprise notebooks are stored in Dataform. When you create or interact with a notebook, Colab Enterprise sends an API request to Dataform. Dataform has the following relevant API quotas:

Dataform quota Colab Enterprise interaction Limit
Total requests per project Notebook (IPYNB file) operations 6,000/minute

Other Dataform quotas such as package installation requests per project or workflow actions per execution don't apply to Colab Enterprise.

Notebook operations

Notebook (IPYNB file) operations count toward the Dataform quota for total requests per project. For example, notebook file operations include the following:

  • Creating, saving, and renaming a notebook.
  • Opening, downloading, and uploading a notebook.
  • Viewing each version of a notebook's revision history and reinstating a previous version.

Usage limits

Colab Enterprise enforces the following usage limits:

Usage limit Value
File size per uploaded notebook

Approximately 20 MB

Working with a notebook that is near the size limit can impact performance.

Request a quota increase

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