Welcome to use Tencent Cloud Load Balancer service (CLB). The CLB service distributes requests from clients to multiple real servers associated with the CLB in the same region by setting a virtual IP address (VIP) as the specified method.

Cloud Load Balancer (CLB) virtualizes multiple bound real servers into an available service pool. The CLB service checks the health status of servers in the service pool and automatically isolates unhealthy servers, thereby resolving single points of failure issues and improving the overall service capabilities of the applications. CLB strictly isolates the traffic of each tenant and offers proactive protection against DDoS. Public network CLB supports Anti-DDoS Basic (https://www.tencentcloud.com/document/product/297?from_cn_redirect=1) by default.

Tencent Cloud Load Balancer service is a solution for multiple servers serving simultaneously, used together with backend servers.
