Quotas and limits

Yandex.Cloud services can be subject to quotas and limits:

• Quotas are organizational restrictions that can be changed by technical support on request.
• Limits are technical restrictions due to the Yandex.Cloud architecture specifics. The limits cannot be changed.

When designing your infrastructure in Yandex.Cloud, plan for the limits as the maximum that Yandex.Cloud can provide you with. Quotas are restrictions that can potentially be increased up to their limit.

Why quotas are needed

Quotas serve as a soft restriction for requesting resources and let Yandex.Cloud guarantee service stability because new users can't take up too many resources for testing purposes. If you're willing to use more resources, you can increase them in the following ways:

• Submit an increase request;
• Contact the technical support and tell us which consumed quotas you need to increase and by how much.

Default quotas and limits for services Yandex.Cloud

Quotas are listed with default values that match the quotas of the trial period.
