Yandex Cloud service quotas and limits

Written by
Improved by
Updated at October 28, 2025

Yandex Cloud services can be subject to quotas and limits:

  • Quotas are organizational constraints that can be changed by support on request.
  • Limits are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

When designing your infrastructure in Yandex Cloud, plan for the maximum limits that Yandex Cloud can provide you with. Quotas are modifiable constraints that can potentially be increased up to the limit values. Quotas do not guarantee that resources are available.

Why quotas are needed

Quotas serve as a soft constraint for requesting resources and allow you to manage cloud service usage: with quotas, new users cannot take up too much resources for testing purposes.

If ready to use more resources, you can increase your quotas in the following ways:

To have your request processed, you must have the quota-manager.requestOperator role or higher (editor or admin).

You can manage quotas with Cloud Quota Manager.

Default quotas and limits for Yandex Cloud services

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

For each quota, the table provides an ID you can use to manage quotas via Cloud Quota Manager.

Read and write operations utilize the same disk resource. The more read operations you do, the fewer write operations you can do, and vice versa. For more information, see Read and write operations.

4 For maximum IOPS, we recommend keeping your read and write operations close to the disk block size (4 KB by default).

5 For maximum bandwidth, we recommend 4 MB reads and writes.

Outgoing traffic filtering

Yandex Cloud automatically blocks traffic sent from Virtual Private Cloud public IP addresses to TCP port 25 of any servers on the internet and Yandex Compute Cloud VMs. The only exception is the traffic sent to Yandex Mail email servers, which is allowed and not blocked.

Yandex Cloud can provide a special public IP address with TCP port 25 opened upon request to the support team if you follow the Acceptable Use Policy. In case you violate the Policy, Yandex Cloud may block outgoing traffic on TCP port 25 again.

For public IP addresses that are already in use, port 25 cannot be opened.
