@long dao thanh Thanks for reaching out to us!
The device connections throttle governs the rate at which new device connections can be established with an IoT hub. The device connections throttle does not govern the maximum number of simultaneously connected devices. The device connections rate throttle depends on the number of units that are provisioned for the IoT hub.
For example, if you buy a single S1 unit, you get a throttle of 100 connections per second. Therefore, to connect 100,000 devices, it takes at least 1,000 seconds (approximately 16 minutes). However, you can have as many simultaneously connected devices as you have devices registered in your identity registry.
Please check IoT Hub quotas and throttling for more details.
