With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load Web Services.Under the idea of Server Load

there is a machine down, it is only one of the db n one of the data can not access it, which we can accept, at least more than before the segmentation of the situation is much better, not the entire DB can not access. In general applications, such machine failure caused by the data is not accessible is acceptable, assuming our system is a high-concurrency e-commerce site? The economic losses caused by single-node machine outages are very serious. In other words, there is still a problem with ou

is not a test. Of course, there is always a solution to the problem. We introduce the concept of clustering , which I call group, that is, each node of the library we introduce multiple machines, each machine holds the same data, in general, many of these machines load, when there is a downtime situation, The load balancer allocates the

group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer distributes the load to the machine that is down when there is an outage. This solves the problem of fault tolerance.As shown, t

Now, basically all enterprises use the network for daily work. In the network operation of an enterprise, the transmission and data sending and receiving processes are not evenly distributed. Then, using Server Load balancer technology can achieve a balanced concept. So how to implement it? If it is not realistic to purchase large load balancing equipment, softwa

Generally, server load balancer distributes client requests to various real backend servers to achieve server load balancer. Another method is to use two servers, one as the Master and the other as the hot backup ), Generally, server load
