The ribbon is a client load balancer that provides good control over the behavior of HTTP and TCP clients. feign already uses the Ribbon, so if you use it @FeignClient , this section also applies. the central concept in the Ribbon is the concept of a specified client. Each load balancer is part of a combination of co

Introduction to load Balancing clusters
Main open source software LVs, keepalived, Haproxy, Nginx, etc.
The LVS belong to 4 layer (network OSI 7 layer model), Nginx belongs to 7 layer, Haproxy can be considered as 4 layer, can also be used as 7 layer
The Keepalived load balancing function is actually the LVS
LVS This 4-tier load
more famous sites and organizations are using LVS set up the cluster system, For example: The Linux portal (www.linux.com), real Company (www.real.com), the world's largest open source website (sourceforge.net), which provides audio and video services to RealPlayer.II. structure of the LVS systemThe server cluster system with LVS is composed of three parts: the most front-end load balancer layer, represent

The LVS architecture uses the LVS to set up the server cluster system has three parts: the most front-end load balancing layer, with
}After the modification, also modify the server listening port, the original content is as follows:server {Listen 80;server_name localhost;......The following changes are completed:server {Listen 8086;server_name 10.0.2.136;......In this way, Nginx starts listening for the local IP (10.0.2.136) 8086 port request after booting, then turns its request to the two IIS sites specified in mylocalsite and forwards the results to the client. If everything is configured correctly, then you can run C:/ngi
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
HAProxy is a proxy software that provides high availability, server load balancer, and TCP and HTTP applications, HAProxy is a completely free proxy solution that provides TCP and HTTP applications quickly and reliably with HAProxy. HAProxy is applicable to websites with large loads. these sites usually need session persistence or layer-7 processing. HAProxy supports tens of thousands of concurrent connecti
