HAProxy is a free and open source software that provides a high availability load balancer and reverse proxy for TCP and HTTP-based applications that spreads requests across multiple servers. It is written in C and has a reputation for being fast and efficient (in terms of processor and memory usage).
HAProxy is used by a number of high-profile websites including GoDaddy, GitHub, Bitbucket, Stack Overflow, Reddit, Slack, Speedtest.net, Tumblr, Twitter and Tuenti and is used in the OpsWorks product from Amazon Web Services.
I’ve heard of almost all of those things.
What’s a HA proxy?
It’s a lolbalancer
Without it we might accidentally Lol or lOL. It would be anarchy
Remember the ROFLCopter era? It was pure chaos!
http://www.haproxy.org/ it’s a load-balancer (it only allows access to devices behind it based on rules).
