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 l

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. Experiment (I.)Experimental purpose: Using Haproxy to do load balancing

First, the problems encounteredWhen we deploy a Web application with an IIS server, when many users have high concurrent access, the client responds very slowly and the customer experience is poor, because when IIS accepts a client request, it creates a thread that consumes large memory when the thread reaches thousands of. At the same time, because these threads are switching, the CPU usage is also high, which makes IIS more difficult to perform. So how do we solve this problem? Second, how 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

multiple UDP sockets on the server and binds the same IP and port, and the client sockets for different source IPs and ports automatically load to different server sockets. In this way, if you want to take advantage of multi-CPU, you can pre-create multiple processes, each of which allocates a UDP socket to handle the sending and receiving of the data (the code implementation can pre-fork multiple processes in the main process, and each process only

The previous article written the Nginx load balancer, this article realizes the high Availability (HA). The overall design of the system is to use Nginx to do load balancing, if there is an nginx single-machine failure, the whole system will not function properly. For the high-availability requirements of system architecture design, we need to solve the requireme

Lvs-nat model: Similar to Dnat, but supports multi-target forwarding, which is multi-objective DnatIt is forwarded by modifying the destination address of the request message to a certain RS rip selected by the scheduling algorithm.Architectural Features:(1) RS should use a private address, that is, RIP should be a private address, each RS gateway must point to the dip(2) The request message and the response message are forwarded through the Director; in high-
