You can create resources in a specific AZ in a region.</p>

Each region is completely independent, improving fault tolerance and stability. After a resource is created, its region cannot be changed.</li><li id="ddm_01_0007__en-us_topic_0185177741_en-us_topic_0184026189_li45875020473">An AZ is a physical location using independent power supplies and networks. Faults in an AZ do not affect other AZs. A region can contain multiple AZs, which are physically isolated but interconnected through internal networks. This ensures the independence of AZs and provides low-cost and low-latency network connections.</li></ul>
