Quotas and limits

    In the Compute Cloud service, the following limitations apply:

    • 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.

    You can view your current account quotas in the managemenet console.

    *

    To achieve maximum IOPS, we recommend performing reads and writes that are 4 KB and less.

    **

    To achieve the maximum possible bandwidth, we recommend performing 4 MB reads and writes.
