Each Alibaba Cloud account has default quotas for Express Connect resources and API operations. You can view and adjust quotas based on your business requirements.
Quotas apply per region or per account and fall into the following types:
General quotas: maximum cloud resources available per account.
API rate limits: maximum API call frequency per account (QPS limits).
Privileges: permissions for advanced features, granted per account.
Express Connect provides general quotas, API rate quotas, and entitlement quotas, and supports adjusting some quotas. You can view quotas or apply for quota increases by logging in to Alibaba Cloud Alibaba Cloud Quota Center. For operation instructions on quota management, see Manage Express Connect quotas.
