Used for load balancing, but its dashboard and reporting could be improved
We use the solution for load balancing The solution's implementation and troubleshooting are not easy. The solution's dashboards and reports could be improved. I have been using HAProxy for 12 years. We didn’t face any issues with the solution’s stability. I rate the solution’s stability an…
PeterForster - PeerSpot reviewer
A highly stable and scalable load-balancing software that offers great technical support
My company is really happy with Kemp LoadMaster as a product. My company is also happy with the support we receive from Kemp LoadMaster. I want Kemp LoadMaster to provide users with better reporting capabilities in relation to TCP packets. In general, the connections that are present in the system require improvement. Feature-wise, Kemp LoadMaster has everything that our company's customers require. Kemp LoadMaster also has features that have supported our company's past projects.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests."
"It improves our scalability and responsiveness services to meet our demanding customer requirements."
"Software defined load balancing allows us to dynamically adjust and codify routing decisions. This speeds up development."
"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."
"The ease of use of the configuration, and great documentation, are the most valuable features for us."
"The anti-DDOS PacketShield filtering solution (embedded in the physical appliances) as well as the BGP route injection are great features and heavily used."
"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."
"It is scalable."
"Great web balancing and remote access balancing."
"I like that this is a Network Load Balancer that can be used practically with any application in the backend. They have how-to guides on how to set up Kemp NLB with Exchange, but you can use it as well for Sharepoint, RDS, or any other back end server."
"When the templates are used, there is not much left to configure and they just work!"
"The security features, load balancing, built-in templates, and the easy to implement virtual IPs are great."
"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."
"There is a simplicity to the setup and configuration."
"The base feature of Kemp LoadMaster load balancing ticks all the boxes but the most valuable features would be the security features Intrusion Prevention (IPS) and Web Application Firewall (WAF)."
"Exchange load balancing and reverse proxy for Skype for Business are key features."
 

Cons

"The solution's dashboards and reports could be improved."
"Documentation could be improved."
"The product does not have any new technologies."
"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."
"Dynamic update API. More things should be possible to be configured during runtime."
"They should introduce one feature that I know many people, including me, are waiting for: HAProxy should have provide hot-swipe for back-end servers. Also, they need a more detailed GUI for monitoring and configuration."
"I would like to see better search handling, and a user interface, with a complete functional graphical unit"
"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."
"So far, the only hitch we have run into is that would have been nice to have an easier method to add allow/whitelist entries into the Access Control lists for virtual services."
"If I had to change something it would maybe be to have a little better reporting graphics that show more details in the reporting. It seems to be a little small in the graphic, and I'm not sure if possible but maybe a GUI page that one can use to monitor if any server goes down."
"Perhaps Kemp could offer some training videos."
"Several elements of the GUI need work. For example, if you have many content switches, it’s difficult to find the ones you need. And where is the search feature?"
"They were still in the process of development, and for example, we set it up in a cluster. So it was one logistical unit built out of two physical devices. And the expected behavior, which I know from other devices, will be formed into a logic cluster. It's that you configure one unit. Then you bring the second unit into this cluster with the already configured primary unit. So the secondary box pulls all the configured ones from its neighbor, does everything automatically, and then synchronizes with this primary neighbor. And then it works, like, one logical unit. And this didn't work with the Kemp's initially, where they caused a lot of issues when building up a cluster, so there were some specials on how to set this up. When we built or set them up for the first time and the months afterward with no new software releases, there were a couple of problems, but in the end, they worked fine. So, they developed a lot and learned from what they've responded to, what we responded to them, and what needs fixing."
"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."
"If there is anything that needs to be updated, the GUI can get a refresh to make it look more like 2020, although it is just a cosmetic change."
"If you want logging for SMTP traffic, you have to enable ESP, which requires you to define allowed IP addresses. That’s irritating, to say the least."
 

Pricing and Cost Advice

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"The licensing fee for the solution is $690 per unit annually."
"When it comes to pricing HAProxy is free."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"HAProxy is free open-source software."
"It is free of cost."
"HAProxy is free in the initial offer. However, pricing can be improved."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"It has a very attractive ratio of price/performance."
"The setup cost and pricing plan is reasonable and will ultimately give you a worthy return."
"It has a great price for the solution they offer."
"Less expensive than Citrix."
"The Kemp LoadMaster is a tremendous value."
"The license varies according to the number of megabits."
"The price of the solution is cheap."
"Download Kemp's VLM trial and take it for a test drive; you will be impressed."
