Cluster technology is a very popular method to improve the system service capability and high reliability (Ha-high availability). By combining multiple independent servers into one cluster, failure can be seamlessly transferred. That is to say, when a server in a cluster becomes a machine, the user status data on it can be seamlessly migrated to other servers in the cluster. In this way, the customers who are using the application can completely feel the impact, greatly providing system reliabil

Therefore, like iptables, lvs directly wor

In the past, running a large web application meant running a large web server. Because your application attracts a large number of users, you will have to add more memory and processors to your server. Today, the 'large server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs. The 'more servers' mode has more advantages than the

F5 is a well-known Server Load balancer product. I believe many people will not know it. So how does it maintain sessions? Let's start with the definition of session persistence. As an image metaphor: Session persistence can be seen as a string of pearls, so we split each Pearl and put it in a different box for storage and then put it into a string, that is, the concept of allocation. So how do we describe

: This article mainly introduces how to set up server load balancer with iis in windows. if you are interested in PHP tutorials, refer to it. Because the project has encountered a large number of image storage problems, although we still have a lot of images (currently up or down 1 TB, it is estimated that the growth rate is 1.3 times per year ), when I think about how to effectively store a large number of
