Procedure

1. In the navigation pane, click IoTDA Instances. On the page displayed, click Buy Instance on the right of Standard Edition.
2. Enter configuration information about the instance. The system automatically calculates the fee based on instance specifications and the pay-per-use mode.

   Parameter	Description
   Billing Mode	Billing mode of an instance. Currently, only Pay-per-use billing mode is supported.
   Region	Region where IoTDA is deployed. Currently, AP-Bangkok, AP-Singapore, AF-Johannesburg, and CN-Hong Kong are supported. NOTE: Select a nearby region to ensure the lowest latency possible.
   Specifications Configuration	SUF unit with free specifications, SU1 unit with small specifications, SU2 unit with medium specifications, SU3 unit with large specifications, and SU4 unit with ultra-large specifications. NOTE: Instance specifications of Standard Edition = Number of units in the instance x Specifications of each unit A Standard Edition instance can contain multiple units of the same type. The maximum number of units in a single instance is 100, and the maximum TPS of upstream and downstream messages of a single instance is 100,000. For example, even if an instance contains 100 S3 units, the maximum TPS of the instance is 100,000. You can increase the number of units in the instance online, for example, upgrading a standard instance from three SU1 units to five SU2 units. An instance cannot contain different types of units, for example, M SU1 units and N SU2 units.
   Enterprise project	This parameter is displayed only for enterprise users who have enabled the enterprise project function. Enterprise projects let you manage cloud resources and users by project. For more information, see Enterprise Management.
   Instance Name	Enter a name for easy management. The value can contain a maximum of 64 characters consisting of letters, numbers, underscores (_), and hyphens (-).
   Description	Provide a description for the instance, which can be a brief description based on the instance user and usage.
