Register, tell a friend about it, or both. If there aren't 7 registered by 5PM MST Monday, May 11th, the class will be "re-planned" (i.e. cancelled).<br></div><div><br data-mce-bogus="1"></div><div>What *is* HAProxy, even? It's software libre for load-balancing. So, it's a tool to help your web-farm be more performant and reliable, and an HTTP router, and a smart filter for your SMTP and SSH. It is the basis of many, if not most, of the load-balancer products in the world. Like PostgreSQL, it's liberally licensed, so proprietary products can be made from it. I personally prefer copyleft, but both copyleft and liberal are libre. In fact, as people that prefer liberal licenses will tell you, liberal is *more* free than copyleft. If BSD were not liberally licensed, there'd be no macOS. Don't say it... Anyway, enough about licenses.</div><div><br data-mce-bogus="1"></div><div>The point is, HAProxy is fast, reliable, and very, very free. It does HTTP and TCP proxy, stats, ACLs, all sorts of good things.</div><div><br data-mce-bogus="1"></div><div>If you want the class to happen, it's up to you! I haven't had and won't have time to do my usual event promotion things, so I'm handing off to you, school.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>--<br data-mce-bogus="1"></div><div>David L.
