What Are the Quota Limits of UCS?

UCS Quotas

Quotas put limits on the quantity or capacity of resources available to users. UCS has quota limits on clusters, fleets, permissions, cluster federations, and Container Intelligent Analysis instances.

  • Cluster quota: specifies the maximum number of clusters that can be connected to UCS. This quota consists of the numbers of Huawei Cloud clusters and attached clusters.
  • Fleet quota: specifies the maximum number of fleets in an account.
  • Permission quota: specifies the maximum number of permission policies that an account can create on the Permissions page.
  • Cluster federation quota: specifies the maximum number of cluster federations that an account can enable.
  • Container Intelligent Analysis instance quota: specifies the maximum number of Container Intelligent Analysis instances that an account can create.

For other cloud services you may also use when running UCS, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Virtual Private Cloud (VPC), Elastic Load Balance (ELB), SoftWare Repository for Container (SWR), and Domain Name Service (DNS), their quotas are independent of UCS and are managed separately. For details, see Quotas.
