- Geographical locations
Select a region based on the geographical location of you and your users.
- Regions in the Chinese mainland
In the Chinese mainland, we recommend that you select a region that is the closest to the geographical location of your users to speed up access. However, in terms of network infrastructures, Border Gateway Protocol (BGP) network quality, quality of service (QoS), and usage of and configurations on Elastic Compute Service (ECS) instances, Alibaba Cloud regions in the Chinese mainland are almost the same. BGP networks ensure fast access to all regions in the Chinese mainland.
- Regions outside the Chinese mainland
Bandwidths provided in regions outside the Chinese mainland are applicable to users in those regions. If you are located in the Chinese mainland, we recommend that you do not select regions outside the Chinese mainland because you may experience high latency if you select those regions.

- Connection between Alibaba Cloud services
If you use multiple Alibaba Cloud services together, take note of the following items:
- ECS instances, ApsaraDB RDS instances, and Object Service Storage (OSS) buckets that are created in different regions cannot communicate with each other over internal networks.
- Server Load Balancer (SLB) cannot balance requests from ECS instances deployed in different regions. ECS instances that you purchased in different regions cannot be deployed on the same SLB instance.
- Resource price
The prices of resources may vary with regions. For more information, see the Pricing page.
- ICP license filing
When you select a region, you must consider the special requirements of some regions. For example, if you purchase an ECS instance in a region in the Chinese mainland and use the instance as a web server, you must apply for an ICP license.
If you want to apply for an ICP license, take note of the following items:- If you want to apply for an ICP license for services in Beijing, select the China (Beijing) region.
- If you want to apply for an ICP license for services in Guangdong, select the China (Shenzhen) region.
Note The approval requirements for ICP licenses vary from province to province. For information about the latest requirements, visit the ICP license application website of the local communications administration.
Zone
A zone is a physical area within a region that has its own independent power grids and networks. The network latency between instances within the same zone is lower than that between different zones.
- If your application requires high disaster recovery capabilities, we recommend that you deploy instances in different zones within the same region.
- If your application requires low latency, we recommend that you deploy instances within the same zone.
