1. network load balancing working principle
Network Load Balancing uses a cluster of two or more host computers working together to provide high availability and scalability for servers. An Internet client uses an IP address or a group of addresses to access the cluster. Clients cannot distinguish clusters from single servers.

First, the problems encounteredWhen we deploy a Web application with an IIS server, when many users have high concurrent access, the client responds very slowly and the customer experience is poor, because when IIS accepts a client request, it creates a thread that consumes large memory when the thread reaches thousands of. At the same time, because these threads are switching, the CPU usage is also high, which makes IIS more difficult to perform. So how do we solve this problem? Second, how t
