Alibaba Cloud allows you to view and manage quotas of your Alibaba Cloud services. You can obtain usage information, apply for increases on quotas, and create alert rules for quotas. This topic describes the prerequisites and procedures for managing service quotas.

Background information

Quota Center allows you to manage the quotas of various Alibaba Cloud services in a centralized manner. ALB and many other Alibaba Cloud services work with Quota Center. If you are using multiple Alibaba Cloud services and want to manage the quotas of all your cloud services in one console, you can use Quota Center.

Alternatively, you can individually manage ALB quotas by using the quota management feature provided in the Server Load Balancer (SLB) console. https://slb.console.aliyun.com/slb/quota

Limits

By default, only Alibaba Cloud accounts are authorized to manage quotas in Quota Center. If you want to allow RAM users to manage quotas, you must first grant the AliyunQuotasFullAccess permission to the RAM users. For more information, see Authorize a RAM User.
