balancing if you want to really understand the content of the seven-tier application layer, you can only proxy the final server and the client to establish three handshake connections, it is possible to accept the client sends the real application layer content of the message, so the seven-tier load balancer is more like a proxy server . As TCP becomes more and more complex, many applications, such as

One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1. NAT (Network address mapping):The NAT mode can support any operating system, as well as private networks, and requires only one Internet IP address, but t

Currently, popular Server Load balancer front-end servers include Apache (with mod_proxy), nginx, Lighttpd, squid, perlbal, and pound. If your domain name service provider provides DNS-level Server Load balancer, or (that is, a domain name randomly points to multiple IP addresses, and the customization is not high ). I

Server Load balancer (SLB) is a load balancing service that distributes traffic among multiple ECs instances. SLB can expand the external service capability of the application system through traffic distribution, and improve the availability of the application system by eliminating spof. (In connection with CDN, CDN uses Server

services. The more famous is www.linux.com and www.real.com.II. system Structure of LVSThe server cluster system with LVS is composed of three parts: the most front-end load Balancing layer (Loader Balancer), the middle server group layer, with server array, the lowest data sharing storage layer, represented by shared storage. All applications are transparent to the user, and the user is only using the hig

Defined:LVS is a shorthand for Linux virtual server, that is, a virtualized server cluster system.Structure:In general, the LVS cluster uses a three-tier structure, the main component of which is: A, Load Scheduler (load balancer), it is the entire cluster to the outside of the front-end machine, responsible for sending the customer's request to a set of servers
