Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"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.""I can't speak to all of the HAProxy features because we don't use them all, but load balancing is very good.""We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host.""We did not need technical support because the documentation is good.""Stability is number one.""Advanced traffic rules, including stick tables and ACLs, which allow me to shape traffic while it's load balanced.""I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring.""The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."

More HAProxy Pros →

"LoadMaster is easy to deploy and understand.""The most valuable feature so far has been the high-availability options that allowed us to add an additional Kemp LoadMaster VLM virtual appliance into our VMware vSphere environment, to provide failover for our existing LoadMaster.""Scalability-wise, I rate the solution a ten out of ten...I rate the technical support a ten out of ten...The initial setup of Kemp LoadMaster is very simple.""One of the most valuable features I like is the ability to block specific cipher suites like RC4, and older protocols like SSL 3.0.""The DNS Load Balancer makes it so that I don't have to worry about site failures.""The pricing of the solution is valuable.""When the templates are used, there is not much left to configure and they just work!""The old process of manually having to redirect Outlook Web Access traffic and Email traffic to a second server is a thing of the past."

More Kemp LoadMaster Pros →

"Dynamic update API. More things should be possible to be configured during runtime.""Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time.""I would like to evaluate load-balancing algorithms other than round robin and SSL offloading. Also, it would be helpful if I could logically divide the HAProxy load-balancing into multiple entities so that I would install one HA Proxy LB application which could be used for different Web servers for different applications. I am not sure if these features are available.""Maybe HAProxy could be more modular.""There is room for improvement in HAProxy's dynamic configuration.""​It needs proper HTTP/2 support.​""There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA ​solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable.""The web stats UI, which provides the status of the health and numbers, could greatly benefit from having a RESTful interface to control the load-balanced nodes. Although there is a hack around the UI (by issuing a POST request to HAProxy with parameters), a RESTful interface would greatly improve the automation process (through Chef and Ansible)."

More HAProxy Cons →

"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking.""Overall, the Kemp LoadMaster has been an all-rounder great product and stable. The free trial and virtual edition make it a breeze for any potential customer to give it a spin before actually deciding to put it on the infrastructure or even talk to the CFO.""It would be very helpful to get all the http/https session logs by default in the log monitor without activating debugging mode like an apache web sever natively does""It lacks an officially supported, well-written SCOM Management Pack.""The only thing that I miss is that the TMG server was giving me live information about who is connected and what is the request about.""When we go serverless, we may again have to revisit this because the configuration needs to be changed. With this change, we can run into a lot of other configurations that we haven't got into, which involve additional expenses. It would be challenging to convince management to buy at that price point. It would be a balancing act of justifying that expense and the value, that is, how it is going to save a bit of time and make our platform secure. It can have better configuration ability. A lot of iterations happen when we have multiple servers pointing to the same domain. If we do not orchestrate carefully, it gets into a loop, which takes away the precious time of the user who is trying to subscribe to a service. It takes a little longer time to realize services as well as web pages.""UI is very basic and unattractive.""It would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."

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."

  • "Download Kemp's VLM trial and take it for a test drive; you will be impressed."
  • "It has a very attractive ratio of price/performance."
  • "​I have control on the licensing and all the prices since I work for a partner.​"
  • "KEMP gives away free trials for 30 days. This can be stretched if you want. During the test, you will have access to KEMP support.​"
  • "It has a great price for the solution they offer."
  • "The license varies according to the number of megabits."
  • "Licensing is yearly and I am going to guess that it is CAN $2000.00."
  • "Any decent product will cost money and if you want great support and a great product, then you will want to spend the money on it."

    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.

    Kemp LoadMaster is a powerful load balancing solution that also serves as a web application firewall. Its primary use case is load balancing and application load balancing, making it an ideal solution for organizations that must distribute traffic across multiple servers. Kemp's integration with an active directory for ESP usage, hosting/deployment of SSL certificates, and pricing are some of its most valuable features. 

    Using Kemp has helped organizations mitigate cross-scripting vulnerabilities, cookie-related issues, and content security policy issues. It has also allowed them to handle everything with Kemp instead of working on each application individually.
