Overview

The IoT platform uses instances to implement data and resource isolation. Currently, the platform provides three editions: basic (shared instance), standard (standard instance), and enterprise (dedicated instance).

  • Basic Edition

    After you subscribe to IoTDA, the platform provides a default shared instance. In the shared instance, only basic device access and management functions are provided, and multiple tenants share compute resources. If you do not purchase instances of other types, the products and devices you create are all in this shared instance.

    Note: Basic Edition is not provided in CN East-Shanghai1.

  • Standard Edition

    In the standard instance, the platform provides more functions (for example, SQL data forwarding) and service combination capabilities, and supports industry-specific solution integration and adaptation. It also isolates instances of different tenants.

    You can experience all functions of Standard Edition free of charge within the limit on the number of messages and devices per day.

    If you need more devices and messages, purchase standard instances.

    Note: The free trial is available only for users who have passed real-name authentication of HUAWEI CLOUD accounts.

  • Enterprise Edition

    After you purchase a dedicated instance, it runs in your specified Virtual Private Cloud (VPC). You can use independent public and private IP addresses to access the platform. Your purchased resources are exclusive to yourself, providing higher resource security and isolation.

For the differences between the instances, see Specifications.

Restrictions on Purchasing Instances

Note the following restrictions to prevent purchasing and creation failures:

  • Restrictions on purchasing standard instances

    Each tenant can purchase only one standard instance.

  • Restrictions on purchasing dedicated instances
    • User permissions

      Before purchasing a dedicated instance, authorize cloud service access. Purchase is available only after the authorization is successful. For details, see Configuring Cloud Service Access Authorization.

    • Instance quota

      A maximum of five dedicated instances can be created in a VPC network.

    • Available IP addresses in the subnet

      At least 10 IP addresses shall be available in a subnet.

Early-stage Planning

  • Public/Private network interworking

    Interworking with the public network: Public network IP addresses are provided by the platform. You do not need to plan them.

    Interworking with the private network: When subscribing to IoTDA, specify the VPC and subnet. By default, IoTDA can be accessed only from the specified subnet. Therefore, provide a properly planned subnet when purchasing IoTDA. If the data transfer function of IoTDA is used, for example, if data needs to be forwarded to Kafka, the IoTDA and Kafka services must be in the same subnet. If you need to forward data to Kafka in the same VPC but in a different subnet, submit a service ticket.

  • VPC

    Determine the VPC network segment. Currently, the VPC supports three network segments: 10.0.0.0/8-24, 172.16.0.0/12-24, and 192.168.0.0/16-24. For details, see Creating a VPC.

    Determine the subnet division. The subnet network segment must be within the VPC network segment.

  • Route table

    Determine the route table. The default route table only ensures that all subnets in the same VPC can communicate with each other. If the routing policy in the default route table cannot meet your requirements, customize a route table. For details, see Route Table Overview.

Configuring Cloud Service Access Authorization

The platform can work with HUAWEI CLOUD services. When you purchase an enterprise instance for the first time, perform access authorization. After the authorization is successful, you can create ports, subnets, and security groups. In addition, you can connect to the VPC Endpoint service so that applications or devices can access the platform through a private network.

  1. Log in to the IoTDA console.
  2. In the navigation pane, click IoTDA Instances. On the page displayed, click Authorize Service on the right of Enterprise Edition.
  3. On the displayed page, click Agree. After the authorization is successful, an agency named iotda_admin_trust is created in Identity and Access Management (IAM).
