Yandex Cloud services can be subject to quotas and limits:
- Quotas are organizational restrictions that can be changed by technical support.
- Limits are technical limitations due to Yandex Cloud architectural features. 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.
Why quotas are needed
Quotas serve as a soft constraint on requesting resources and enable Yandex Cloud to guarantee service stability: 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:
- Generate a request for a quota increase. You must have the
quota-manager.requestOperatorrole or higher, such aseditororadmin. - Contact technical support and tell us which quotas you want increased and by how much.

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 To achieve maximum IOPS, we recommend performing read and write operations whose size is close to that of the disk block (4 KB by default).
5 To achieve the maximum possible bandwidth, we recommend performing 4 MB reads and writes.

Outgoing traffic filtering
Yandex Cloud automatically blocks traffic sent from Virtual Private Cloud public IPs 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 can block outgoing traffic on TCP port 25 again.
For public IPs that are already in use, port 25 cannot be opened.
