CLB supports creating Anycast CLB instances. Anycast CLB is a load balancing service that supports cross-region dynamic acceleration. CLB VIP is published in multiple regions. The client connects to the nearest POP and forwards traffic to a CVM instance through the high-speed internet of Tencent Cloud IDC.
Anycast CLB can achieve network transfer optimization and multi-entry nearby access and reduce network jitter and packet loss, which can ultimately improve the service quality of in-cloud applications, expand the service scope, and streamline backend deployment.
This feature is currently in beta test. To apply for a trial, submit an application for beta test eligibility.
Anycast means that when the same IP publishes a route in multiple locations simultaneously, the routing algorithm will deliver user traffic to the nearest router.
Advantages of Anycast CLB:
The Anycast CLB architecture is as shown below:
The VIP of Anycast CLB is published to multiple regions around the world. The client connects to the nearest POP and forwards access traffic in an ultra-fast manner to a CVM instance over Tencent Cloud private network.
An Anycast publishing region is where an accelerated IP address is published, i.e., the POP where Anycast CLB VIP is published. The client accesses the nearest POP. Currently, Anycast CLB supports simultaneous publishing in the following regions: Beijing, Shanghai, Guangzhou, Hong Kong (China), Toronto, Silicon Valley, Frankfurt, Virginia, Moscow, Singapore, Seoul, Mumbai, Bangkok, and Tokyo.
Just like a region of generic CLB instances, an Anycast CLB region is the one you selected when purchasing an Anycast CLB instance or the region where your real server resides. Currently, Anycast CLB is available in most regions.
- The anycast capability of Anycast CLB is implemented by binding an Anycast EIP to a private network CLB instance.
- Anycast EIP can be bound to private network CLB instances but not classic private network CLB instances.
If you are in the gaming industry, you may hope that the players from different places are in the same server region or that your branches around the globe can share the same IDC. You can use Anycast CLB to deploy real servers in one region (such as Guangzhou), purchase an Anycast CLB instance in that region and select the publishing regions as needed. In this way, players or employees can obtain the nearby access to the same real servers.
Anycast CLB has been widely used in gaming acceleration. Through Anycast CLB, game requests can have nearby access to Tencent Cloud and get to game servers through Tencent Cloud private network, greatly shortening the public network path and reducing problems such as delay, jitter, and packet loss. Compared to the traditional acceleration, Anycast CLB requires no extra deployment of traffic receivers at the entry and eliminates the need for zoning, thus simplifying DNS deployment.
This feature is currently in beta. Make sure that your application for beta test eligibility has been approved before using it.
