Quota limits

Default product quotas are as follows. Submit a Ticket to request additional quotas.

BCC instance

• A single region can have up to 50 Postpaid instances simultaneously.
• The recycle bin supports a maximum of 50 instances at the same time.

Description:

• Released BCC instances do not consume quotas. Postpaid BCC instances that are neither released into the recycle bin nor unreleased due to overdue payments or expired renewals will occupy the quota.
• The aforementioned quotas apply to a single region, with each region's quotas calculated independently.

Cloud disk server

• A single region can have a maximum of n*5 CDS data disks, where n represents the BCC count.
• Each disk can have up to 1512 snapshots simultaneously, including 512 manual snapshots and 512 automatic snapshots.
• The count of disks a single instance can mount depends on the instance model. For Intel 4th/5th/6th-generation and AMD 2nd-generation instance families, 32C+ specifications support up to 16 CDS data disks; specifications below 32C and AMD 1st-generation support up to 5 CDS data disks. For Intel 7th-generation and AMD 3rd-generation +, it varies by specifications. See Specifications for details.

Image

• A single region can have up to 20 images simultaneously.
• A single image in one region can be shared with up to 50 users.
• A single region can accept up to 20 shared images.

Key pair

• A single region can have up to 500 key pairs.

Deployment group

• A single region can create 10 deployment sets.
• Each deployment group within an availability zone can host up to 10 BCC instances. Hence, the total number of BCC instances in a single deployment group within a Baidu AI Cloud region equals 10 multiplied by the number of availability zones in that region.

Elastic network interface

• The count of elastic network interface cards mountable to a single instance depends on the specifications. For 6th-generation and earlier models, the maximum count of mountable elastic network interface cards is min{cpu cores, 8}. For 7th-generation and later, it varies by specifications. Details can be found in Specifications.
