HAProxy Community Edition is a free, open source reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is presented as suited for very high traffic web sites.
Well Suited: Perfect for hosting your own website. And, I don't mean just an individual with a port of MySpace. I mean an industrial strength, commercial grade replacement for Microsoft IIS. If you need a web server that provides a feature-rich environment with support for multiple sites (hosted in the same server), with such features as virtual hosting, and modular feature design, than Apache Web Server is right on the money. Less Well-Suited: Single page, small feature-set websites. Apache is a lot of trouble for developers to set up, just to send/receive JSON strings of a few bytes. You're really better off using something smaller and faster/simpler (lighttpd for example).
It prevents a single server failure from being a downtime event by adding redundancy to every layer of your architecture. A load balancer facilitates redundancy for the backend layer (web/app servers), but for a true high availability setup, you need to have redundant load balancers as well. So it is well suited for all production related servers and less suited for individual servers that do not require redundancy.
Apache is Open Source, governed well (the foundation) and probably the most stable computing platform ever.
Apache is probably one of the most customizable and configurable pieces of software that I have ever run across in more than 30 years of development.
If there is something that Apache can not do, then you need to ask yourself; should I be doing that? The point here is that it is a solid solution and seems to only integrate other technologies that are of the highest caliber.
Apache will live forever and you can not go wrong with it.
My understanding is a lack of support for UDP traffic
One mistake in the haproxy.cfg prevents the entire thing from starting rather than only affecting the part of the config file that may have a typo of some other syntax problem.
It is very easy to use. I was able to find a lot of documents for it on the internet. Very good community support. There are lots of examples available to try. We mostly use a command-line user interface to interact with it. The CLI is also super easy to use and very easy to interact with
I give this rating because there is so much Apache documentation and information on the web that you can literally do anything. This has to do with the fact that there is a huge Open Source community that is beyond mature and perhaps one of the most helpful to be found. The only thing that should hold anyone back from anything is that they can not read. RTFM, my friend. And I must say that the manual is excellent.
We haven't used customer support. We mostly used the community version. We build a multi-node HAProxy cluster with HA to the proxy itself using opensource plugins available. With the support available on the internet and the documents available we don't need to use much customer support.
The comparison with other products from IBM or Oracle is difficult. These are mostly software that has to be paid for. The only fair comparison at eye level is probably the NGINX web server: It is also free and offers even higher performance. In the meantime, there is also a paid Plus version of NGINX. This has extended support and special functions.
We chose HA Proxy because it is cheaper than a hardware balancer, it is an open-source solution with a large community behind it and with constant updates. It also allows custom scripts according to needs.HA Proxy is a solution used in many internet sites like GitHub, Reddit, Twitter, and Tuenti.
Apache web server helped us in building client applications without much investment in the underlying server configuration which gives us the ability to start on a new project quickly and upgrade its resources as and when needed.
Using software which is well-supported by a community of open source contributors makes tasks easy and affordable when need help since a couple of minutes on Google saves a couple of dollars every time and you don't need a specialized support person unless there is something significant needing to be changed.
Significantly lower investment vs competitors. In the case of F5s we have Virtual Editions so we're paying for the hardware to run it on top of the several thousand dollar licenses that are required for each pair and we currently have a pair of F5s per client so there's a huge potential for cost savings there.
Requires our network engineers to learn a new skill or our Systems engineers to take on the responsibility of managing the load balancers. It's not a huge difference either way, but it does impact the way we have done business in the past.
