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

One, load balancing load Balance: built on the existing network structure, it provides an inexpensive and effective way to extend the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability. This means that it can be shared across multiple operating units, such as Web servers, FTP servers, enterprise critic

Nginx Server Load balancer dual-host High Availability If the Web server cluster is used as a city pool, the load balancing server is equivalent to the city gate, and its importance is self-evident. If the "City Gate" is closed, the access to the outside world will be broken. If a server is balanced, when the server fails, the whole website will be inaccessible.

Nginx reverse proxy and Server Load balancer I. Introduction Reverse Proxy(Reverse Proxy) means to use a Proxy server to accept connection requests on the internet, and then forward the requests to the server on the internal network, return the result obtained from the server to the Client Requesting connection from the internet.

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

As shown in the following figure, this task consists of the high-availability server Load balancer component and cache DNS. High-availability server Load balancer component requirements: optimize some key links in the business system architecture, load balancing for TCP laye

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
