Fast and reliable load balancing reverse proxy.

A Juju charm deploying and managing HAProxy on machines.

HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments. It features connection persistence through HTTP cookies, load balancing, header addition, modification, deletion both ways. It has request blocking capabilities and provides interface to display server status.

This charm simplifies initial deployment and "day N" operations of HAProxy on VMs and bare metal.
