round robin load balancing

Load balancing is composed of multiple servers in a symmetrical way of a server set, each server has the equivalent status, can be provided to the external service alone without the assistance of other servers. Through some load-sharing technology, the externally sent requests are evenly distributed to one of the servers in the symmetric structure, and the server

18.6 Load Balancing Cluster introductionThe software that realizes load Balancing cluster is: LVS, keepalived, Nginx, Haproxy and so on. The LVS belong to four layer (network OSI model), Nginx belongs to seven layer, haproxy can be considered as four layer, also can be used as seven layer.LVS, Haproxy this four-tiered

DNS load balancing is the first implementation of load balancing technology. Configuring the same name for multiple addresses in a DNS configuration file is configured with multiple A records pointing to a different IP, and the client will randomly obtain one of the addresses when querying this a record. It is not diff

the hosts on the server cluster, so that they are responsible for processing these requests and giving them, and the process of allocating requests is generally the kind of round-robin request pictured above, and of course there is an address translation technology that becomes NAT technology (also called Do network address translation technology is to request the address from the routing address to the cluster server in the IP address of a server, w

on the Web server. (1) The upstream command of the scheduling algorithm nginx is used to specify the backend servers used by proxy_pass and fastcgi_pass, that is, the reverse proxy function of nginx, therefore, the two can be combined to achieve load balancing, while nginx also supports multiple scheduling algorithms: 1. Round Robin (default) each request is dis

following network structure to achieve Load Balancing for the two PostgreSQL servers,Http://www.linux.gov.cn/himages/Linux/lvs_001.gifIt is easy to implement Load Balancing for the two PostgreSQL servers: 192.168.3.2 and 192.168.3.3. Use the following commands: Echo 1>/proc/sys/NET/IPv4/ip_forwardIpvsadm-a-t 192.168.

What is load balancing?When the performance of a single server reaches its limit, we can use a server cluster to improve the overall performance of the site. Then, in the server cluster, you need a server to act as the dispatcher's role, all of the user's requests will be first received by it, the dispatcher then according to the load situation of each server to

Application Microsoft Application Center 2000 Component Load Balancing Technology Overview Author: Chris Rees This technical overview will discuss Microsoft Application Center (Application Center) Component Load Balancing technology (CLB). Introduction Microsoft Application Center (Application Center) is part of the

protocols, such as the Outlook Web App. So on the load balancer this layer, no longer special need for the load office weighing products to support client affinity.Let me say a few more words, from the level of the mailbox connection to the level of the Web connection request. As mentioned earlier, older versions of Exchange have problems requiring clients to re-authenticate without client affinity support

In multi-core CPUs, to make full use of the performance of multiple CPUs, you must ensure a good load balance for the tasks allocated to each CPU. Otherwise, some CPUs are running and others are idle, so they cannot take advantage of multi-core CPUs.There are usually two solutions to achieve a good load balancing: static load
