Buying an Instance

Procedure

1. In the navigation pane, choose IoTDA Instances, click Buy Instance, and select Enterprise.
2. Enter configuration information about the instance. The system automatically calculates the fee based on Instance Specifications and Required Duration.

   Parameter	Description
   Billing Mode	Billing mode of an instance. The value is fixed at Yearly/Monthly.
   Region	Region where IoTDA is deployed. Currently, CN North-Beijing4, CN East-Shanghai1, and CN South-Guangzhou are supported. NOTE: Select a nearby region to ensure the lowest latency possible.
   Network	Select an available VPC and subnet. Create a VPC on the VPC console.
   Security Group	Select a security group. Create a security group on the VPC console.
   Public Network Access	Set this parameter based on your requirements. If configured, devices can access the platform via the Internet.
   Private Network Access	If you select Create Provide Network Access Point, a VPC endpoint is automatically purchased and an access address is automatically allocated. If it is not selected, private network ingestion is still required. You can purchase VPC endpoints for connection.
   Access Ports	You can configure access ports or use the default ports. The following ports are provided: Application access: HTTPS (443) and AMQPS (5671) Device access: CoAP (5683), CoAPS (5684), MQTT (1883), MQTTS (8883), and HTTPS (443)
   Instance Version	Select Enterprise.
   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 details, see Enterprise Center Overview.
   Tags	Tags are key-value pairs, which are used to identify, classify, and search for instances. Instance tags are used to filter and manage instances only. For details, see Instance Tag Management.
   Instance Name	Set a name for easy management. The value can contain a maximum of 64 characters consisting of letters, numbers, underscores (_), and hyphens (-).
   Cryptographic Algorithm	General cryptographic algorithms (such as RSA and SHA-256) and SM series commercial cryptographic algorithms (Chinese cryptographic algorithms such as SM2, SM3, and SM4) are available.
   Description	Provide a description for the instance, which can be a brief description based on the instance user and usage.
   Required Duration	Select a duration as required. You can select Auto-renew so the instance will be automatically renewed when it expires.

3. Click Buy.
4. Confirm the specifications and click Pay.
5. On the payment page, select a payment method and click Pay.

Buying a Standard Edition Instance

The standard instance provides configurable instance specifications. You can purchase more economical instances based on your service model.

Before the purchase, browse the overall process for a more efficient operation.

Procedure

1. In the navigation pane, choose IoTDA Instances, click Buy Instance, and select Standard.
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 is supported..
   Region	Region where IoTDA is available. Currently, AP-Bangkok, AP-Singapore, AF-Johannesburg, LA-Sao Paulo1, and CN-Hong Kong are supported. NOTE: Select a nearby region to ensure the lowest latency possible.
   Specifications	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 are available. You can obtain the recommended instance specifications based on the required upstream and downstream TPS. 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 details, see Enterprise Center Overview.
   Tags	Tags are key-value pairs, which are used to identify, classify, and search for instances. Instance tags are used to filter and manage instances only. For details, see Instance Tag 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.
