Billing rules
DSC provides data security features based on its editions. Each edition includes different default security capabilities. You can also purchase feature extensions for your instance. DSC is billed based on the selected edition, feature specifications, and subscription duration.
The billing cycle for a subscription resource corresponds to the subscription duration specified in the order (UTC+8). A billing cycle starts at the exact time the resource is activated or renewed and ends at 00:00:00 on the day after the expiration date.
Billing components
DSC billing consists of default specification fees and value-added service fees. The following figure shows the billing components.

Log storage | DSC provides 50 GB of free log storage per month for every 1 TB of OSS protection and 200 GB for each database instance. For example: You purchase an Enterprise Edition instance. The Feature Extension Modules are 1 TB of Detection And Response - OSS Protection, 1 Detection And Response - Database Instance, 1 TB of DBAudit - OSS Protection, and 1 DBAudit - Database Instance. Including the Default Specifications for DBAudit and Detection and Response, your instance has 8 TB of OSS protection and 8 database instances. The free log storage is calculated as follows: 8 × 50 GB + 8 × 200 GB = 2,000 GB. |
