An availability zone (AZ) refers to a physical area where power and networks are independent of each other in the same region. An AZ is a collection of one or more physical data centers, equipped with independent power, cooling, and networking. The distance between availability zones is less than 100 KM. Multiple AZs in a Region are connected through high-speed optical fibers to meet customers' requirements for constructing high-availability systems across AZs.

· The purpose of dividing availability zones is to ensure that the faults in the availability zones are isolated from each other (except for large-scale disasters or power failures) to avoid spreading and thus guarantee service continuity. By starting an instance in an independent availability zone, users can protect their applications from failure in a single location.
· Cloud products in different availability zones in the same region but in the same virtual private cloud communicate with each other over Intranet and can be directly accessed using Intranet IP addresses.
l Relationship Between Region and Availability Zone
Each region is independent, and availability zones in different regions are completely isolated. However, availability zones in the same region are connected using low-latency links.
Currently, eSurfing Cloud has provided cloud services in multiple regions around the world. You can choose the regions and availability zones as needed.
