Specifications of Standard Edition

IoTDA provides standard instances for device access and service processing. Each Huawei Cloud user can enable up to one standard instance in the same region. If it cannot meet your requirements, submit a service ticket. You can select the type and number of units in the standard instance to determine the total number of messages allowed per day between devices and the platform. If you increase the number of units of the same type, the total number of messages will increase and the function limitations will change as well.

After an instance is enabled, you are billed based on the usage duration (days) and unit type and quantity you select. For details about product prices, see Price Calculator. Select the required configuration and check the configuration fee at the bottom of the page. For details, see Billing Overview.

NOTE:
  • A standard instance can be configured with multiple units of the same type, for example, five SU1 units, but cannot be configured with different types of units, for example, two SU1 units and three SU2 units. You can change the number and type of units at any time. For example, you can upgrade two SU1 units to five SU1 units or two SU1 units to two SU2 units. You can enable only one SUF unit but 100 SU1, SU2, SU3, or SU4 units. An SUF unit can be upgraded to an SU1, SU2, SU3, or SU4 units. After the upgrade, the original SUF unit is no longer retained.
  • Number of messages: For details about the number of messages to be billed, see Billing Items. If the message limit is reached, IoTDA generates an alarm and rejects new messages. Upgrade the unit specifications or increase the number of units if necessary.
  • Message size: Max. size for messages using MQTT: 1 MB. Max. size for messages using LwM2M over CoAP: 1 KB. Messages whose sizes exceed the limit will be rejected. Messages are counted as one unit up to 4 KB; any excess is counted as additional units.
  • Number of devices: A standard instance supports up to two million registered devices. To increase the quota, submit a service ticket. All registered devices can go online concurrently. When only an SUF unit is enabled, up to 1,000 devices can be registered.
  • TPS of upstream and downstream messages: Max. throughput of upstream and downstream messages per second, that is, the total number of messages exchanged between devices and the platform. The quotas of standard instances are determined by the type and number of units. Submit a service ticket for special requirements if necessary.
  • For limitations on other than unit specifications and quota, see Limitations.

Calculating the required instance specifications:

  • Scenario: A user enables the IoTDA standard instance and plans to register 100,000 devices. The average number of concurrent online devices per day is 10,000. Each online device sends a message (smaller than 4 KB) to the platform every 5 seconds on average. No API calls or push messages are involved. The daily working duration is 8 hours.
  • The TPS of upstream and downstream messages is 2,000 (10,000 devices/5 seconds × 1 message per device). The total number of messages per day is 57,600,000 (8 hours × 60 × 60 seconds × 2,000 TPS). In this case, you can purchase two SU3 units, which support 2,000 TPS, 80 million messages per day, and up to 2 million registered devices, and cost about USD2,100 (USD1,050 x 2). Alternatively, you can purchase 20 SU2 units. Bills are generated and deduction is triggered every day.
