Haproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which 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. The haproxy runs on the current hardware and can support tens of t

In the MySQL world, Haproxy is often used as a software load balancer. Peter Boros explains how to use the Percona xtradb cluster (PXC) to set it up in a previous message. So it only sends the query to the applicable node. The same method can be used for general master-slave settings to read the load and spread across multiple nodes. However, with MySQL replication, another factor starts to work: replication latency. In this case, the mentioned Percon

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. Then we use haproxy to replace NLB to achieve CAS load ba

HAProxy: Implements an event-driven, single-process model that supports tens of thousands of of concurrent connections to provide highly available, load-balanced, and proxy service solutions for TCP and HTTP applications, especially for high-load Web sites that require a durable connection or a 7-tier processing mechanismProxy (HTTP):Forward Proxy:Reverse proxy:Agent role: Web caching (acceleration), reverse proxy, content routing (forwarding requests

Previously, we made a service that implements the LDAP query proxy through Haproxy + Keealived. I felt pretty good and decided to use it to proxy public Exchange requests. TMG is not updated, and the configuration is a little complicated, and the service will die if it does not move. If you cannot understand the following information, go to my previous article Haproxy + keepalived to configure LDAP proxy.

So then we started using haproxy to build the cluster. One, top
