Tencent Cloud Load Balancer (CLB) distributes requests from clients to multiple backend CVMs associated with the CLB in the same region as specified by setting a virtual IP address (VIP).
CLB virtualizes multiple CVMs bound with it into an available cloud service pool. CLB checks the health status of the CVMs in the pool and automatically isolates unhealthy ones, thus resolving single points of failure issues and improving the overall service capabilities of the applications. If your service is under DDoS attack, CLB will provide you a defense capability against 300 GB of attack traffic.
Tencent Cloud CLB is a solution for multiple servers to serve at the same time, and it needs to be used in combination with CVMs.
