Many websites do not need a large scale at the beginning, but as a website designer, expansion must be taken into account from the very beginning to build a highly scalable architecture. The so-called scalability means that the system can improve the carrying capacity of the system through scale expansion. After all, the vertical expansion of the server itself will soon be restricted, and the single machine will soon be unable to meet our needs, therefore, this capability is often achieved by ad

Reverse proxy Load Balancer ApacheOne, reverse proxy1.1 Introduction Reaction AgentThe reverse proxy method refers to a proxy server that accepts connection requests on the Internet, then forwards the request to a server on the internal network and returns the results from the server to the client requesting the connection on the Internet, Reverse. At this point the proxy server appears as a reverse proxy s
