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.

Great WAF - low-maintenance solution that performs as advertised
The solution can be improved with the development of a SIP engine because it is difficult to manage SBCs. All SBCs are really tough to write rules for. If we could put this in front of an SBC to have the right rules to possibly block the traffic, that would be very helpful. The solution can also improve the relationship between Loadbalancer.org and Metaswitch, or now, Microsoft because Metaswitch was purchased by Microsoft. They both position themselves as certified but don't always talk to each other. I wish there would be closer integration between the solution and the vendors when either release new upgrades to their product line. Often we find issues on either end post upgrades.

Quotes from Members

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

Pros

"The pricing of the solution is valuable."
"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)."
"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."
"Security is considered the most effective feature in Kemp LoadMaster."
"The Global WAF has saved us more than one time from unwanted traffic."
"It is an easy-to-use, user-friendly interface, and you can set up a new VIP in a couple of minutes."
"Failover is seamless and our services are rock solid."
"LoadMaster is easy to deploy and understand."
"We have about 30,000 connections going through at any one time and it's fine, it doesn't seem to sweat. It doesn't get overloaded."
"The connection that this solution helps our servers maintain has been most useful."
"It helps us to route the traffic to the available servers. If we didn't have Loadbalancer we would fail to set the end-user and it would cause a failure in the cluster."
"I found scalability in Loadbalancer.org valuable."
"It does what it’s supposed to do which is balancing an important intranet site we are using, so if one server dies, the second becomes active straight away."
"Most important for us that it makes sure that the load is distributed and that we always have access to the end servers."
"Loadbalancer is easy to use. It performs well, with low latency."
"We can more easily set up a test environment, because you can easily configure your forms. It makes it more flexible for us, to convert our test environment to a production environment, without having to change DNSs on the outside. You just configure the forms on the inside. So without changing the actual endpoint for the end user, we can create completely different networks in the background."
 

Cons

"Some of the support documentation seems to make assumptions that the person installing or configuring is experienced with the product or concepts."
"In my opinion, the layer seven loads balancing that we're mainly using for web servers, doesn't seem to pick up when there are issues at the application level."
"Some documentation is out of date versus the new version, and things have been moved​."
"In the web interface, there are a lot of settings in the different menus and it would be helpful if there were an interactive help system or tooltips to help the administrators find and configure the right settings."
"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."
"We have experienced at least one problem with stability, although it was fixed with an upgrade."
"SNMP and/or RESTCONF management, in order to collect many counters, for plotting in a central application need to be improved."
"The interface from Loadbalancer.org should be improved."
"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."
"It doesn't have the bonding capability feature."
"They're mostly designed to balance a particular type of traffic. I wanted to load balance DNS, and they just don't do it the way that we wanted to. So they're not used as DNS load balancers."
"If I have to say something, I suppose they could add an automated configuration backup to an FTP location (or something similar) so you don’t have to manually do it. I don’t see this as a problem, of course, as the configuration rarely changes and we only need one backup, but maybe for other users that feature would be handy."
"Originally we had some stability issues with it, so they replaced it with a new box and it's fine."
"I would like it if Loadbalancer had the ability to make rules for specific shared bots."
"You can run into an issue when one engineer passes the case over to another engineer after their shift and they don't know what the first engineer worked on up to that point."
 

Pricing and Cost Advice

"It is well-priced and licensing is very flexible."
"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.​"
"This is a cost-efficient product."
"Download Kemp's VLM trial and take it for a test drive; you will be impressed."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"Less expensive than Citrix."
"The price is lower than other options."
"At $2,500 USD, this is absolutely a fantastic buy for the money!"
"I think it’s very affordable."
"The costs associated with Loadbalancer.org depends on the technology. For some, we need to pay, but others are open, so they're free."
"I’m not entirely sure about the rating since I'm not very technical. I haven't thoroughly compared the ratings. So, if you're asking for my impression so far, I would rate it around five out of 10."
"It was easy to upgrade the license for unlimited clusters and servers. Pricing is fair."
"Licensing fees are paid annually."
"It filled a requirement for our project, and it did so at lesser cost than their competitors.​"
"I love that they do not price on some arbitrary throughput rating where you are guessing at what the load balancer is going to handle."
"For now, it's stable."

Kemp LoadMaster is a vendor designed and supported load balancing platform focused on core load balancing technologies.  Kemp supports server load balancing (SLB) and global server load balancing (GSLB).  LoadMaster supports edge authentication including two-factor authentication, single sign on (SSO), Kerberos, and LDAP among other models.  Kemp LoadMaster also has the ability to provide fully functional web application firewall (WAF) services. LoadMaster is a software-based solution available as a VM for all major hypervisors, cloud marketplace (AWS, Azure, etc.) and hardware.  Kemp simplifies the load balancing technology through a simple to use GUI and over 80 templates for the most commonly used applications. Kemp is a global organization with 100,000+ deployments and the top rated load balancer on Gartner's Peer Insights with over 150 recent ratings: www.gartner.com/reviews/market/application-delivery-controllers LoadBalancer.org uses software based on opensource HAProxy and opensource Pound.  LoadBalancer.org also utilizes other opensource projects such as STunnel and Ldirectord.  You will get the features within the free HAProxy code (and others) with a LoadBalancer.org GUI.  This information is documented in their current Administration Manual:  http://pdfs.loadbalancer.org/loadbalanceradministrationv8.pdf This means that the functionality is dependent on the opensource community for updates and there will be a lag for these features to be rolled into LoadBalancer.org's product. From a performance perspective, both vendors probably have solutions to meet your needs.  I also believe that both solutions can support the applications that you plan to load balance.  The more important questions to ask yourself are 1) how easy it will be for you to configure and deploy the load balancing technology and 2) how painful will it be for you to manage and support the technology operationally. First, I believe that you will find both solutions relatively easy to deploy since both vendors focus on core load balancing functionality (SLB and GSLB).  Having said that, Kemp offers pre-built application templates for many commonly used applications to make the configuration that much easier: https://kemptechnologies.com/docs/.  Kemp focuses on making the work easy for the customer. Second, for operational support, I cannot speak for LoadBalancer.org's support organization, but Kemp's is stellar with a 99% customer satisfaction feedback rating.  As mentioned above, one concern for vendors that rely heavily on opensource code is the delay from an opensource project update to the time those changes get incorporated into a vendor's officially released and supported product.  We (the IT industry) have seen problems with this model on a regular basis throughout time.  A good example is the delay for all vendors as OpenSSL code was updated from 1.0.1 to 1.1 to 1.1.1 and all of the discovered security vulnerabilities with prior versions. Major caveat:  I work for Kemp.  Having said that, I have worked with load balancing technology for over 20 years (starting with Cisco Local Director), and have worked with, and for, multiple load balancing vendors.  My goal is to be factual.  I have sourced my data where possible and if I have not, I recommend that you fact check my information.  Ultimately, I believe with the correct data, you will make the right decision.
