While I have not tested this specific use case, I would start by exploring map files [1] and/or stick tables [2]. Map files can be updated on-the-fly through the HAProxy Runtime API. With stick tables you can persist a session/client based on anything found within the request headers, which would include a users session id.

IMO you would use OpenResty as a web server and HAProxy as a load balancer in front of it. HAProxy focuses on being a high-performance load balancer. OpenResty is built ontop of NGINX and many of the load balancing features in NGINX are locked behind their "Plus" product, all of which are provided by default within HAProxy. In order to take advantage of these features in OpenResty (such as active health checking and DNS service discovery) you would need to use Lua scripts where in HAProxy they are implemented in the core.

Thanks for the feedback. I've provided a few replies below but I think you have made some great points and I will share them internally.

> - the site does not do a good job of describing the products and what they do.

The page does lead off by telling you it is a software load balancer, but I agree, we can do a better job of giving more information on the product itself. Most people who pursue HAProxy Enterprise are already familiar with HAProxy. With that said, we're actually working on a complete overhaul to this page and I believe the new version will address this.

> - it is hard to find requirements from the first page.

This is just a reference point and typically organizations are working closely with a sales engineer.

> - is there a simpler HA setup than the 3 layer one here:

A simpler version is found under active/standby here [1]

I have not tested that use case but I do not think so. It has the ability to parse FIX tag values and make routing decisions from the initial Logon message.

It has the ability to route by FIX tags. You can find an example here [1]

You can pass along timing data from every aspect of the request [1] currently there are approximately 20 events supported. You can also send over just about anything that can be stored within an HAProxy variable / header through a tag. Here's an example configuration for HAProxy (simple) [2] (advanced) [3] and the OpenTracing specific configuration (simple) [4] (advanced) [5]. I've included both simple and advanced configurations.

Well said, to add to this, HAProxy is also closing the gap on convenience with its recent addition of AWS EC2 service discovery [1] and Consul service discovery integrations [2].

Author of the blog post here, happy to answer any questions about this release.

disclaimer: I work at HAProxy Technologies

More control/flexibility (i.e. cloud provider usually gives you a limited number of "checkboxes" that they want you to be able to modify), generally better observability (HAProxy timing metrics [1] and session state at disconnection codes [2] are very helpful for debugging), and granular control over timeouts [3]. You also get builtin rate limiting [4], which from what I have seen with most cloud load balancers usually requires an up-charge through their "WAF" product.

Better health checking, circuit breaking, and layer4/layer7 retries [5].

Another consideration is whether you have spiky traffic patterns. For AWS load balancers at least, they need time to "warm up" to larger traffic levels. If you manage your own load balancing tier you can scale on demand.

I'm curious to know what you mean by this? It's not like it can't handle more that is just what their peak workload was. With only 18% CPU usage at peak it's clear that it could handle much more.

> when they want to have full control on what is going on, understand what the code is doing to better optimize everything else around it, faster shipping cycles and being able to implement what you want with out waiting for the next shipping cycle with commercial software, community and knowledge base around it etc.

I'm a bit confused by this - I work for HAProxy Technologies and we do have an enterprise product. Many of our customers contribute code directly into the community and we backport those features into the latest enterprise stable version. This means they do not have to wait until the next shipping cycle to take advantage of a new feature. There's also a large community & knowledge base around HAProxy.

Your reasoning may be right when dealing with "closed source enterprise software" but it doesn't line up when we start talking about open source/open core.

There's an opentracing integration coming very soon! We were hoping to have it available with the 2.2 release but there were still a few things to finalize.

Freenode #haproxy

Interesting, that is the first I have heard of a "%" matching problem. You might want to join the community on IRC/Slack and share your config. I'd be more than happy to give you some pointers around upgrading to 2.x.

Very exciting times! Author of blog post here I'd be more than happy to answer any questions about this release.
