This topic describes the regions of simple application server and network connectivity. Select region for your server to ensure stable network access.
Regions
Concept
Regions are geographical locations where Alibaba Cloud data centers are deployed. Regions are typically named after the cities where the data centers are deployed. For example, the data centers of the Malaysia (Kuala Lumpur) region reside in Kuala Lumpur.
Select a region
When you create or purchase an Alibaba Cloud resource, you must select the region in which you want to deploy the resource. After the resource is created or purchased, you cannot change the region of the resource.
When you select a region, you must take note of the items that are described in the following table.
Item | Description |
Geographical location | Services deployed in a region that is geographically closer to your users are more responsive when your users access the services. 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 have purchased a cloud networking service to connect your 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 region. For more information, see product pages or resource buy pages. |
Supported regions
Area | Scenarios | Region |
The Chinese mainland | Your business is deployed in the Chinese mainland. Important If you are in the Chinese mainland and use servers in the Hong Kong (China) region or regions outside the Chinese mainland, you may experience high network latency. Select a region that is closest to your target customers to reduce latency. | China (Ulanqab), China (Heyuan), China (Beijing), China (Shanghai), China (Hangzhou), China (Shenzhen), China (Guangzhou), China (Chengdu), China (Qingdao) , China (Hohhot) |
Regions outside the Chinese mainland | Your business is deployed outside the Chinese mainland. Important The network is not directly connected to the Chinese mainland. If you are in the Chinese mainland and access servers in Hong Kong (China) or other regions outside the Chinese mainland, you may experience high network latency and packet loss. | China (Hong Kong), Singapore, Malaysia (Kuala Lumpur), Indonesia (Jakarta), Philippines (Manila), Thailand (Bangkok), Japan (Tokyo), South Korea (Seoul), UK (London), Germany (Frankfurt), US (Virginia), US (Silicon Valley) |
Network connectivity
Network | Description |
Internal network | Servers use the internal Local Area Network (LAN) of Alibaba Cloud for data transmission. This allows free internal communication services within the same region.
|
Internet | Servers use the Internet for data transmission. Alibaba Cloud assigns public IP addresses to instances to enable communication with other terminals on the Internet. This allows servers to access and be accessed by the Internet. Note The bandwidth is the maximum rate of inbound or outbound Internet data transmission. This metric is not guaranteed. During peak hours, if resource contention occurs, bandwidth may be limited, and packet loss may occur. Simple application servers are not suitable for scenarios with strict requirements for Internet connection quality. If your business requires high-quality Internet connections, we recommend purchasing ECS instance that use pay-by-bandwidth billing.
