how load balancer works

systems or different hardware. For example, a cluster that provides Web Services is a large Web server. However, cluster nodes can also provide services separately.3. Features: based on the existing network structure, Server Load balancer provides a cheap and effective method to expand server bandwidth and increase throughput, enhance network data processing capabilities, and improve network flexibility an

The server Load balancer of the Oracle RAC server distributes new connection requests to the node with the smallest load based on the number of connection loads of each node in the RAC. When the database is running, the PMON process of each node in RAC updates the connection load of each node to service_register every

Clusters, such as buying a generation to push the server down and put a piece he's quite a cluster, and load balancing is to get this big bunch of servers to work on average. He is called load Balancer, as shown in:For example, I use 192.168.8.155 to act as a pic host 1 and PIC Host 2 with Server A, 192.168.8.166, and 192.168.8.177来 as follows:Then start modifyin

Nginx can be used not only as a powerful web server, but also as a reverse proxy server. nginx can also implement dynamic and static page separation according to scheduling rules, server Load balancer can be performed on backend servers in multiple ways, such as round robin, IP hash, URL hash, and weight. Health Check of backend servers is also supported. If there is only one server and the server goes down

Server Load balancer in ASP. NET sites: Based on the HTTP protocol, we may find that we need to solve two problems: first, to achieve Server Load balancer, we need a Server Load balancer. You can use DNS round robin to obtain diff

The LVS architecture uses the LVS to set up the server cluster system has three parts: the most front-end load balancing layer, with

1. Story ReviewIn my previous blog, I built two Web servers and then built an nginx load balancer server on the front end to distribute the requests to two different servers (http://blog.51cto.com/superpcm/2095324). The previous test is not a problem because the test program is a static web site that is purely static and does not change. Later I set up on both the web to build a WordPress service, and then

Based on the huge network structure, the use of cluster servers brings a lot of traffic and other load problems. In contrast, Server Load balancer technology has also emerged. Every technology requires Product Support. Now let's get to know one of F5 Server Load balancer. Fi

I. Concepts of reverse proxy and Server Load balancer Before understanding the concepts of reverse proxy and Server Load balancer, we must first understand the concept of a cluster. Simply put, a cluster is a server that does the same thing, such as a web cluster, database cluster, and storage cluster, the cluster has

Since we have configured Two CAS servers, it is very easy to configure Server Load balancer in exchange 2013 to enable these two servers to provide Server Load balancer services, without the concept of CAS array, Server Load balancer
