The current development trend of the website for the use of network load balancing is as the scale of the website increases according to different stages to use different technologies:One is through hardware. Common Hardware includes expensive NetScaler, F5, radware, array, and other commercial load balancers, it has the advantage of a professional maintenance team to maintain these services. The disadvantage is that the cost is too large. Therefore, it is not required for small network services

Recently, the company had a project where users worried that a single machine could not afford the most users, and they required to use the application cluster. We designed the application cluster architecture based on the application situation.

Because the company needs to be on-line HTTPS, so for HTTPS need to do stress testing, using the same encryption strength of the certificate, respectively, Haproxy and nginx to do stress testing, and then CPU usage comparison:The following are 1000 request stress tests for the same URL and background server:First time Haproxy 1000 times HTTPS pressure test650) this.width=650; "src=" Http://s2.51cto.com/wyfs

Description: The following references the contents of the sixth chapter of "Building a highly available Linux server" Fuqin.It is relatively simple to build a high-availability environment for load balancing, mainly to understand the principles. This article describes the pros and cons of three load balancers so that they can be used in real-world production applications by demand.At present, the online environment in the application of more load balancer hardware has F5 big-IP, software has Lvs

: This article mainly introduces the summary of the lvs, nginx, and haproxy transit modes. if you are interested in the PHP Tutorial, refer to it. Lvs, nginx, and haproxy are the three most common high-availability load balancing software.

1. Introduction to HAproxy HAproxy is a high-performance proxy server. It provides Lay4 and Lay7 proxies, featuring Healthcheck, Server Load balancer, and access control. It can support tens of thousands of concurrent connections with excellent performance. In addition, the HAproxy operating mode enables it to be easily and securely integrated into the current ar

Haproxy implements reverse proxy and load balancingReverse Proxy Server features: web Cache (acceleration), reverse proxy, content routing (forwarding requests to specific servers based on traffic and content types), Transcoder cache: reducing redundant content transmission; reduces bandwidth and network bottlenecks, reduces request pressure on the original server, and reduces transmission latency. Public cache can be used by everyone, for private cac
