This document lists the quotas and system limits that apply to Cloud FTP.
- Quotas have default values, but you can typically request adjustments.
- System limits are fixed values that can't be changed.
Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.
The Cloud Quotas system does the following:
- Monitors your consumption of Google Cloud products and services
- Restricts your consumption of those resources
- Provides a way to request changes to the quota value and automate quota adjustments
In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.
Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.
For more information, see the Cloud Quotas overview.

Cloud Storage quotas and system limits
Cloud FTP manages resources in Cloud Storage, such as objects and folders. This means that the resource naming requirements, quotas, and system limits for Cloud Storage also apply to Cloud FTP. For more information, see the following:
