Let's start with a quick look at what is load balancing, which is interpreted literally to explain the average load sharing of n servers, not because a server is under-loaded and idle on a single server. Then the premise of load balancing is to have more than one server to achieve, that is, more than two units can be.Test environmentBecause there is no server, th

HAProxy for Server Load balancer
HAProxy provides high availability, Server Load balancer, and TCP and HTTP application-based proxy. It supports Virtual Hosts and is a free, fast, and reliable solution. HAProxy is especially suitable for websites with extremely high loads, which usually require session persistence or l
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
