HAProxy for Server Load balancer
HAProxy provides high availability, Server Load balancer, and TCP and HTTP application-based proxy. It supports Virtual Hosts and is a free, fast, and reliable solution. HAProxy is especially suitable for websites with extremely high loads, which usually require session persistence or layer-7 processing.
HAProxy is a free, fast, and reliable proxy solution that supports high availability and server load balancer. It is also suitable for proxies for TCP and HTTP-based applications. For some websites with high load, HAProxy is particularly suitable. HAProxy supports tens of thousands of concurrent connections. It is easy to configure and can easily integrate into o
Haproxy is a popular cluster scheduling tool, with many similar cluster scheduling tools, such as LVS and Nginx. In comparison, LVS performance is the best, but the construction of relatively complex, Nginx upstream module support cluster function, but the cluster node health Check function is not strong, performance is not haproxy good.

Haproxy is especially useful for Web sites that are heavily loaded, which typically require session maintenance or seven-tier processing.
Haproxy implements fully transparent Exchange proxy service
I. background
The company recently used the Exchange mail system to build a highly available mail system architecture. Front-End Server Load balancer uses Microsoft's NLB to achieve cas load balancing. However, some problems have also been found in the solution implementation project. using NLB to generate a large number of broadcast reports in the network causes serious packet loss problems.
In the Internet era, the backend system architecture, often can hear the high-availability cluster, load-balanced cluster and other system architecture solutions, including load balancing hardware-based F5, big-IP, and software-based LVS (based on the Linux operating system implementation, performance and hardware-based performance comparable), Nginx, HAProxy (based on third-party application implementation) and so on, this article describes the insta
