AIA can help publish an elastic IP to multiple regions by way of the Anycast technology to implement the following features:
All user requests and responses can come in and out of the nearest Tencent Cloud access point, and only one set of service cluster, database, and storage node needs to be deployed at the backend. With the aid of Anycast, the backend service will be available in multiple regions through Tencent Cloud's dedicated private network connection. In contrast, in a traditional mode, one set of cluster or storage node needs to be deployed in each region to serve users nearby.
AIA helps avoid slow connection to the internet, and services are not affected by the congestion on the internet, cross-carrier issues, and ISP failures.
Anycast is capable of avoiding internet congestion.
ISP networks may fail from time to time, and Anycast can be used to block the failures.
The following concepts can help you better understand AIA:
For more information on the concepts, please see Glossary.
To provide Anycast service, public cloud vendors must have interconnection network nodes deployed across regions and support cross-region network scheduling. AIA offers the following basic capabilities：
