Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks.""It improves our scalability and responsiveness services to meet our demanding customer requirements.""The VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this.""HAProxy's TCP load balancer is excellent and super stable.""Software defined load balancing allows us to dynamically adjust and codify routing decisions. This speeds up development.""HAProxy Enterprise Edition has been rock solid. We have essentially had no downtime caused by our load balancers in the last 10 months, because they’ve worked so well. Previously, our load balancers caused us multiple hours per year in downtime.""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.""We don't have a problem with the user interface. it's good."

"We find it valuable because it is compatible with our existing Azure solution.""The health probe is pretty good for your backend health. It tells you whether it's communicating and talking to the endpoint correctly. It is quite useful.""The solution is easy to set up.""I rate Microsoft Azure Application Gateway's scalability a ten out of ten. My company has more than 1000 users who use it daily.""We can control what rules should be used and what should be disabled.""The most valuable feature of the solution is the web application firewall (WAF).""The most valuable feature of Microsoft Azure Application Gateway is its ease of use.""I like the tool's stability and performance."

More Microsoft Azure Application Gateway Pros →

"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.""Pricing, monitoring, and reports can be improved.""HAProxy could do with some good combination integrations.""There is room for improvement in HAProxy's dynamic configuration.""The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added.""We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process.""If nbproc = 2, you will have two processes of HAProxy running. However, the stats of HAProxy will not be aggregated, meaning you don't really know the collective status in a single point of view.""The GUI should be more responsive and show the detailed output of logs."

More HAProxy Cons →

"There is room for improvement in the pricing model.""It could be easier to change servicing.""The monitoring on the solution could be better.""The graphical interface needs improvement because it is not user friendly.""The solution has many limitations. You cannot upgrade the VPN to the application gateway. So I started with version one, which has limited capabilities, and they provided version two. And unfortunately, I cannot upgrade from v one to v two like other services. So I have to decommission the version one and create a new one with version two. Also the version one was complex with the certificates uploading the SQL certificates.""The working speed of the solution needs improvement.""The security of the product could be adjusted.""Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."

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."

  • "It is not expensive."
  • "Every solution comes with a license and cost. Microsoft provides the license and the total cost is for the maintenance every year."

  • "There is some additional cost, such as extended support."
  • "The cost is not an issue."
  • "The solution is reasonably priced compared to other solutions."
  • "The pricing is based on how much you use the solution."
  • "The solution is paid monthly. The solution is highly expensive."

    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.

    Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 - TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.
