Understanding Tencent Cloud's infrastructure helps you design applications that are fast, resilient, and compliant. This lesson covers regions, availability zones, and the network backbone.
A region is a geographic area where Tencent Cloud operates data centres. Each region is independent — data does not automatically replicate between regions.

|---|---|---|
| Guangzhou | ap-guangzhou | South China hub, one of the earliest regions |
| Shanghai | ap-shanghai | East China business hub |
| Beijing | ap-beijing | North China, government and enterprise |
| Chengdu | ap-chengdu | Western China coverage |
| Nanjing | ap-nanjing | East China expansion |
| Hong Kong | ap-hongkong | International traffic, no ICP required |
| Singapore | ap-singapore | Southeast Asia hub |
| Tokyo | ap-tokyo | East Asia coverage |
| Frankfurt | eu-frankfurt | European Union coverage |
| Silicon Valley | na-siliconvalley | US West coverage |
| Virginia | na-ashburn | US East coverage |
| Mumbai | ap-mumbai | India coverage |
| São Paulo | sa-saopaulo | South America coverage |
| Seoul | ap-seoul | South Korea coverage |
| Bangkok | ap-bangkok | Thailand coverage |
Tencent Cloud operates 30+ regions with 70+ availability zones worldwide.

├── Zone 2 (ap-guangzhou-2)
├── Zone 3 (ap-guangzhou-3)
├── Zone 4 (ap-guangzhou-4)
├── Zone 6 (ap-guangzhou-6)
└── Zone 7 (ap-guangzhou-7)
↕ Low-latency private links ↕
If one AZ experiences an outage, resources in other AZs continue operating.
Tencent has invested heavily in its global network:
