Serverless

The capacities of serverless DB instances automatically change based on application requirements. You can start using the DB instance first and then pay as you go.

Billed Items

**Table 1** Billed items
Billed Item	Description
DB instance	You are billed for the selected instance specifications. The billing starts immediately after the instance is purchased. For details, see Billing Rules.
Storage space	You do not need to select storage when purchasing a DB instance. Storage will be scaled up dynamically based on how much data needs to be stored. It is billed hourly on a pay-per-use basis.
Backup space	GaussDB(for MySQL) provides free backup space equal to the amount of your used storage space. If the backup space usage exceeds 100% of your provisioned database storage, the additional part will be billed based on the backup pricing.
(Optional) Public network traffic	GaussDB(for MySQL) instances are accessible from both private and public networks, but the traffic from public networks is billed.
(Optional) HTAP instance	Standard HTAP instances are in OBT and are free.
