This topic describes the definition of regions in Alibaba Cloud and how to select a region. This topic also describes all regions in which IoT Platform is available and the instances that are supported in each region.
Definition
Regions are geographical locations where Alibaba Cloud data centers are deployed. Regions are defined based on the cities where data centers reside. For example, the China (Shanghai) region indicates that the data center resides in Shanghai, China.
Select a region
When you create or purchase an Alibaba Cloud resource, you must select the region where you want to deploy the resource. After the resource is created or purchased, you cannot change the region where the resource is deployed.
The following table describes the items that you must take note of when you select a region.
Item | Description |
Geographical location | A region that is closer to the geographical location of your users provides lower latency and higher access speed. We recommend that you select a region based on your requirements for network latency. |
Communication between cloud services over an internal network | Important If you purchased a cloud network service to connect cloud services, ignore this item.
|
Resource price | You can select a region based on your budget. The prices of resources may vary based on the regions. For more information, see the product page or buy page of your resource. |
