load balancing is mainly through the server node to install the device specifically for load balancing, such as F5, and software load balancing is to complete the request distribution work by installing some software with load ba

cheap and effective method to expand server bandwidth and increase server throughput. It enhances network data processing capabilities and improves network flexibility and availability. "Server Load balancer" can be seen everywhere in daily life. At the peak of a supermarket, only 10 customers can be served. If 20 customers need services during the activity, they may be queued up, in this way, the shopping

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

If you have experience in cluster, server load balancer, and dual-machine hot standby, you will be able to answer the question: I am using a mysql database web script written in php. If cluster, server load balancer, and dual-machine hot standby are implemented, is there an all-in-one solution? I mean, what I know now

Heartbeat + LVS build a high-availability server Load balancer Cluster 1. Introduction to heartbeat: The Heartbeat project is an integral part of the Linux-HA project, which implements a high-availability cluster system. Heartbeat service and cluster communication are two key components of a highly available cluster. In the heartbeat project, the Heartbeat module implements these two functions. This cluster
