You can query the remaining quota amount for resources through the Server Load Balancer console. If the remaining quota of a resource is insufficient for your requirements, you can apply to increase the quota.


  1. Log on to the Server Load Balancer console.
  2. In the left-side navigation pane, choose SLB Lab > Quota Management.
  3. On the Quota Management page, you can view the usage of the SLB resources and the privileges of your account.

  4. To increase the quota of a resource, click Apply in the Actions column to submit a quota increase application.
    • Quantity for Application: the number of resources you require. The quota you apply must be a number that is greater than the current quota. For more information about the resource limits of SLB, see Limits.
    • Reason for Application: the detailed reason for application, including the use scenario and the necessity of applying for a quota increase.
    • Mobile/Landline Phone Number: the mobile or landline phone number of the applicant.
    • Email: the email address of the applicant.

  5. Click OK.
    The system automatically determines whether the quota application is reasonable. If it is unreasonable, the application enters a Rejected state, and if it is reasonable, Approved. If the application is approved, the quota is automatically upgraded to the applied number.
  6. To view the quota application history, click Application History in the Application History column.
