Data centers are distributed in the capital cities of five major regions in China. The physical location of these data centers is the node availability region.

After the load balancing instance is created successfully, the region cannot be changed

Data center geographical distribution

• Nanjing, China: Nanjing, Jiangsu Province
• Dalian, China: Dalian, Liaoning Province
• Shenyang, China: Shenyang, Liaoning Province
• Guangzhou, China: Guangzhou, Guangdong Province
• Shenzhen, China: Shenzhen, Guangdong Province
• Inner Mongolia, China: Hohhot, Inner Mongolia Autonomous Region
• Beijing, China: Beijing
• Hong Kong, China: Hong Kong Special Administrative Region

Regional advantages

• Nanjing, China: Superior geographical location and ultra-low delay access throughout the country.
• Dalian, China&Shenyang, China: With a defense of up to 300G, your business is no longer afraid of the challenge of DDoS attacks, and has a good access experience.
• Guangzhou, China: The South China area has ultra-low delay access and multiple international exports.
• Shenzhen, China: Ultra low latency of access in South China, and scarce resources in Shenzhen.
• Inner Mongolia, China&Beijing, China: The benchmark of IDC's intensive operation and the northern node of the 8+2+X strategy. The cloud base has passed the rigorous test of industry manufacturers and can provide international standard T4 computer rooms. The base adopts natural air cooling cycle technology and modular design, which makes the energy consumption of the data center far lower than the industry average.
• Hong Kong, China: The T3+class I computer room standard adopts an 8-wire dual link design, with three lines directly connected to the mainland and five lines providing international bandwidth access, covering Hong Kong, Southeast Asia and other regions, without filing.

How to select a region

When purchasing a load balancing instance, we recommend that you consider the following

• Select Nearby, select a region close to you or your customers to reduce latency and improve access speed.
• Reference price. Different regions have the same configuration, but the price is different. Please refer to the cloud load balancing pricing page for details
• Relationship with other products: ECS (The selected region should be consistent with the region where your load balancer is located.)

The regional correspondence between load balancing and back-end servers is as follows:

• Nanjing, China: Nanjing, China
• Dalian, China: Dalian, China, Shenyang, China
• Inner Mongolia, China: Inner Mongolia, China, Beijing, China
• Shenzhen, China: Shenzhen, China
• Hong Kong, China: Hong Kong, China
