Differences in billing methods and features

Public instances of the new version, public instances of the previous version, and Enterprise Edition instances use different billing methods. Instances of each type can manage resources such as the number of devices that can be connected to IoT Platform, the messaging transactions per second (TPS), and the message forwarding TPS. Instances of different types provide different service capabilities. The following table describes the differences in service capabilities.

Item	Public instances of the previous version	Public instances of the new version	Enterprise Edition instances
Supported regions	China (Shanghai) Singapore Japan (Tokyo) US (Virginia) US (Silicon Valley) Germany (Frankfurt)		Standard Enterprise Edition instances: China (Shanghai) China (Beijing) China (Shenzhen) Japan (Tokyo) Singapore Germany (Frankfurt) US (Silicon Valley) US (Virginia)	MQTT instances andExclusive Enterprise Edition instances: China (Shanghai) China (Beijing) China (Shenzhen)
Service Level Agreement (SLA) availability	N/A.	N/A.	The standard SLA is 99.95%, and the high availability SLA is 99.99%. Only the standard SLA is supported in the Singapore, Japan (Tokyo), Germany (Frankfurt), US (Silicon Valley), and US (Virginia) regions.
Billing methods	Pay-as-you-go. For more information, see the following topics: Messaging fees Device access fees OTAOTA upgrade billing	Free of charge.	Subscription. For more information about the billing rules, see Subscription Enterprise Edition instances.
Maximum number of online devices	The specifications are fixed. For more information, see Limits.	The specifications are fixed to 50.	You can select specifications based on your business requirements. The available specifications vary based on the across different instances. The actual specifications displayed on the buy page prevail.
Maximum number of devices that you can create		The specifications are fixed to 500.	The maximum number of devices that you can create is 10 times the specified maximum number of online devices.
Messaging TPS	The specifications are fixed. For more information, see Limits.	The specifications are fixed to 5.	You can select specifications based on your business requirements. The minimum specifications are 100. The maximum specifications vary based on the across different instances. The actual specifications displayed on the buy page prevail.
Message forwarding TPS		The specifications are fixed to 5.	You can select specifications based on your business requirements. The minimum specifications are 100. The maximum specifications vary based on the across different instances. The actual specifications displayed on the buy page prevail.
Auto scaling	Not supported.	Not supported.	Supported.
Instance-level monitoring and alerting	Not supported.	Not supported.	Supported.
Data services	Not supported.	Not supported.	Only Standard and Exclusive Enterprise Edition instances in the China (Shanghai), China (Beijing), China (Shenzhen), Singapore, and US (Virginia) regions support all features of data services. Standard and Exclusive Enterprise Edition instances in the Japan (Tokyo), Germany (Frankfurt), and US (Silicon Valley) regions support only the time series data storage feature of data services. For more information about the specifications of the features of data services, see the Billable items section of the "Subscription Enterprise Edition instances" topic. For more information about data services, see Data services.
Link WAN	Supported.。 IoT Platform and Link WAN（Link WAN）support mutual access to public instances，You can connectLoRaWANprotocol devices。 For more information, see，seeConnect LoRa devices to IoT Platform in public instancesLoRaConnect LoRa devices to IoT Platform。	Not supported.。	Only in China (2（Shanghai）) region Exclusive Enterprise Edition instances,，Link WAN service is supported and provided free of chargeLink WANservice。 Link WAN（Link WAN）does not provide Enterprise Edition instance services，and cannot access Enterprise Edition instances of IoT Platform。Therefore,，to connectLoRaWANprotocol devices，must use the Link WAN service within the instance toLink WANservice to completeLoRagateway configuration。 For more information，, seeBuild a dedicated enterpriseLink WANnetwork。
Resource groups	Not supported.	Supported. All public instances of the new version belong to the default resource group. You can change the resource group of a public instance of the new version.	Supported. When you purchase an Enterprise Edition instance, you can specify a resource group to which you want to add the instance. For more information about resource groups, see What is Resource Management?

Differences in authentication methods

IoT Platform instances of different types support different authentication methods for device connections. The following table describes the differences in authentication methods.

Feature	Public instances of the previous version	Public instances of the new version	Enterprise Edition instances
Connections over Alibaba Cloud virtual private clouds (VPCs)	Not supported.	Not supported.	Supported.
Fixed IP addresses	Not supported.	Not supported.	Supported.
Custom endpoints	Not supported.	Not supported.	Only Exclusive Enterprise Edition instances support custom Message Queuing Telemetry Transport (MQTT) endpoints and certificates.
Unique-certificate-per-device authentication	Supported. Directly connected devices support this authentication method over the MQTT or HTTPS protocol. Gateway sub-devices support this authentication method over the MQTT protocol.
Preregistration-free unique-certificate-per-product authentication	Not supported.	Not supported.	Devices support this authentication method over the MQTT protocol in the following regions: China (Shanghai) and China (Beijing)
Pre-registration unique-certificate-per-product authentication	Supported. HTTPS protocol: devices in all regions except the China (Beijing) and China (Shenzhen) regions. MQTT protocol: devices in all regions that are supported by IoT Platform.
X.509 certificate-based authentication	Not supported.	Not supported.	Only cloud gateway devices connected to Exclusive Enterprise Edition instances support this authentication method.
ID²-based authentication	Only China (Shanghai)2（Shanghai）、Singapore regions support this feature。	Not supported.	Only devices in the China (Shanghai)2（Shanghai）、Singapore region support this authentication method.
