Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"HAProxy potentially has a good return on investment""Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.""We did not need technical support because the documentation is good.""The feature that I have found the most valuable is that it works for my use case of application load balancing. I'm using it for PeerSense, and it's easy enough for PeerSense.""It is scalable.""I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring.""I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy.""We don't have a problem with the user interface. it's good."

"I find the solution’s community support and documentation most valuable. Compared to HAProxy, have found a lot of documentation and community support on Quora. If you would be asking me as a developer whether to choose this product, I would recommend this since it has good community support, documentation, and signature updates. The configuration of HAProxy is also very tedious. However, NGINX’s configuration is very simple.""The most valuable features are the gateway and the ability to publish to sites.""The web proxy and the database proxy are excellent.""It's lightweight software that can handle heavy loads efficiently.""When I worked in a security research center, we tested NGINX to support DoS and DDoS attacks, and its results were great.""The load balancing module, which is equivalent to LTM, is the focus of the PSE. So far, the features of both are identical. I believe NGINX has more features for securing these services, but in terms of load balancing, both are massive solutions.""When you use NGINX, you have more options and power.""Its versatility and capabilities make it invaluable for implementing patches and fixes when necessary."

More NGINX Plus Pros →

"I would like to see better search handling, and a user interface, with a complete functional graphical unit""HAProxy could do with some good combination integrations.""HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets.""There is room for improvement in the pricing model. It could be cheaper.""The configuration should be more friendly, perhaps with a Web interface. For example, I work with the ClusterControl product for Severalnines, and we have a Web interface to deploy the HAProxy load-balancer.""Sometimes it's challenging to get through the log, and you need a log to understand what is going on. It isn't easy to map the logging with the documentation, and every time I read the log, I have to pull out the documentation to understand what I'm reading.""The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs.""While troubleshooting, we are having some difficulties. There are no issues when it is running; it is stable and very good; however, if there is a troubleshooting issue or an incident occurs, we will have issues because this is open-source."

More HAProxy Cons →

"I would like to see the Grafana integration in NGINX which is already present in HAProxy. Grafana integration will help the solution visualize all the data analytics on the dashboard which is currently not present.""They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing.""It would be good if NGINX provided a graphical user interface.""The scalability could be improved.""Our most challenging part was to run an older PHP website reverse-proxied through NGINX. That was not fun.""The user interface could be improved.""The biggest room for improvement would be to allow NGINX Core machines to cluster for memory zones in some way with a plug and play module. ​""NGINX Plus is moderately priced, but it could give better value for money."

Pricing and Cost Advice
  • "HAProxy is free software. There are optional paid products (support/appliances)."
  • "The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy."
  • "Very good value for the money. One of the simplest licensing schemes in this category of products."
  • "Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
  • "If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
  • "We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
  • "I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
  • "The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."

  • "​NGINX is a free tool in Brazil. There are some companies which do support it.​"
  • "The price is the cost to contract support with a specialized company, usually during consulting hours.​"

    Reviews from Real Users

    Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

    “I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.

    NGINX Plus is a versatile solution that offers load balancing, caching, proxying, and API deployment capabilities. It can be deployed on private or public clouds and is ideal for building CDN solutions. The solution can also be used to secure web applications and replace web services like Apache. 

    NGINX has helped organizations improve functioning, reduce downtimes, and offer a DevOps-friendly solution. Its community support and documentation are highly regarded, and its configuration is more straightforward, making it a recommended choice over HAProxy.
