HAProxy Community Edition vs. NGINX

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.

Nginx is well suited for serving any static content - whether that be images, JS files, HTML files, CSS files, videos, etc. If you have a high-traffic website, Nginx will be a great fit because it handles large number of requests extremely efficiently. Nginx has full support on Unix systems, but only has limited support on Microsoft Windows machines.

• Allow traffic to systems to be distributed evenly, providing high availability
• Allow restrictions to resources using OAuth tokens
• Allow load balancing of databases

• Straight-forward configuration format that users of all skill levels can learn, and yet is powerful enough for the huge breadth of features that Nginx provides.
• Massive scale right out the box. We've never had a Nginx instance overwhelmed by requests, and if we did it would be trivial to spin up more Nginx instances to handle the load.
• SSL termination means that we can deliver content over HTTPS without needing our individual services to require TLS support. This saves us a lot of time and headache while keeping us secure.
• Nginx is open-source and free, meaning that anyone can use it to power their services, from individual projects to billion-dollar websites.

• 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.

• Nginx often requires some initial configuration. It's worth doing, because you'll end up with great results, but it can be slightly daunting for someone to get started using it. Apache might have a leg up in that regard--When you install Apache, typically it's just about ready to do what you want already. But the issue with Apache is that most people skip the extensive tuning phase required after that, and with nginx it becomes more just a part of the configuration process.
• Sometimes, the configuration syntax, even though it's powerful and terse, isn't the most intuitive. Luckily there's plenty of documentation about what things mean and how to accomplish certain things. There may not be much that can be done about this--to have a powerful web server, you need a powerful-enough configuration language.
• The nginx brand is somewhat fragmented, and it can be confusing. There's the open source nginx web server, which I've primarily been referring to. But then there's NGINX Plus, a premium subscription-based service which works with a range of other NGINX products (NGINX WAF, NGINX Amplify, NGINX Controller). I've met a number of people who weren't very familiar with nginx, and instinctively went to nginx.com first, and from there it seems like everything costs money. It's only when they realize there's a different site, nginx.org, that they find what they went looking for.

Great value for the product

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

Front end proxy and reverse proxy of Nginx is always useful. I always prefer to Nginx in overall usability when you have application server and database or multiple application servers and single database i.e. clustered application. Nginx provides really good features and flexibility which helps the system administrator in case of troubleshooting and also from the administration perspective. Also, Nginx doesn't delay any request because of internal performance issues.

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.

Community support is great, and they've also had a presence at conferences. Overall, there is no shortage of documentation and community support. We're currently using it to serve up some WordPress sites, and configuring NGINX for this purpose is well documented.

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.

I have found that [NGINX] seems to perform better throughout the years with less issues although I've used Apache more. I would definitely recommend [NGINX] for any high volume site and I've seen this to usually be the case from most provided web hosts who will pick [NGINX] over alternatives

• 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.

• When we first migrated our primary bidding environment architecture to Nginx, it was under duress due to Apache's inability to keep up when we consolidated away from an HAproxy model to a central HTTP proxy. So we even when we did not know what we were doing, we were able to make it work in a bad situation, and everyone was quite happy.
• The biggest complaint I have is that I find the module compilation requirements for nginx+ rather burdensome. If we pay for Nginx+, I'd love to see then have pre-built modules for ready for each release of more modules. We are spending our own time engineering an in-house solution for module testing for nginx+ releases, which is disappointing.
• I've also, as the primary Nginx person at my organization, inserted my expertise into other projects, and have saved our company lots of money getting rid of big $$$ appliances for general SSL proxying.
• Speaking of Nginx replacing SSL appliances, we had an instance where we had to suddenly enable elliptic-curve SSL ciphers and our big $$$ appliances (you know who they are), were falling over. Even their SSL accelerator cards, after all, are just a few extra cores to process SSL. But in an environment of our size, we use DNS to spread the load to hundreds of frontend proxies with dozens of cores each to spread this load out, all at a lower price than ONE of the appliance pairs running Nginx. We couldn't even tell the change in load in our Nginx architecture when we enabled the ciphers.
