Apache HTTP Server is selected as the front-end Server Load balancer, and two Tomcat clusters are selected at the backend. The selected configuration method is session sticky (sticky session ), this method forwards requests from the same user to a specific Tomcat server to avoid session replication in the cluster. The disadvantage is that the user only communicates with one server, if the server is down, it

In this article, we use Nginx server load balancer to build high performance. in NETweb Application 1, we have a preliminary understanding of Nginx. next

Since the release of this series, I have received replies from many friends! Thank you very much. At the same time, many friends have asked some questions, some of which are basic questions. Due to the time, they will not reply to them one by one. If they do not understand, I hope you will learn by yourself! Although this series is not difficult, many of the knowledge is required by default, such as the concept, principle, and Web farm of Server Load

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission. I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking mode enables complete master-slave switchover. Generally, the gateway of the server must po

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

I know what server load balancer and high concurrency should be used to solve this problem, but I don't know how to do it even though I have no experience in the concept of server load balancer and high concurrency, I searched for nginx to achieve load balancing and high con
