Multiple ADSL load balancing in Linux Preface: Many tools can be used to implement the functions bundled with ADSL, such as RouteOS, vyatta, and panabit. However, my company usually uses many Linux systems. I was inspired by RouteOS and verified whether Linux can be implemented. After searching for information on the Internet, it is found feasible. Today, we fina

Server Load balancer is a server set composed of multiple servers in a symmetric manner. Each server is equivalent and can provide services independently without the assistance of other servers. Through a load balancing technology, requests sent from outside are evenly distributed to a server in the symmetric structure

options: Client Affinity: A cookie is assigned to requests from different clients, and then the cookie is followed to identify which server the request should be handled by. Host name Affinity: Based on host name for sticky processing, there are two provider that can be used: Microsoft.Web.Arr.HostNameRoundRobin: Ensure that the server is distributed as evenly as possible Microsoft.Web.Arr.HostNameMemory: Allocate according to memory usage, ensure the memory usage
