Anycast CLB is a load balancing service that supports multi-region dynamic acceleration. An Anycast CLB VIP is published in multiple regions. Each client accesses the nearest POP, and the access traffic to different POPs is forwarded to CVM instances through the high-speed internet of Tencent Cloud IDC.
Anycast CLB can optimize network transfer and achieve multi-entry nearby access, reducing network jitter and packet loss. It improves the service quality of applications on the cloud, expands the service scope, and streamlines backend deployment.
Note:
Anycast CLB is currently in beta test. To try it out, please submit a ticket.
