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

"It has greatly fortified the performance and uptime of our front-door email ingress, simplified and segmented mail routing, and reduced admin overhead for mail issue resolution and troubleshooting."
"LoadMaster is easy to deploy and understand."
"The configuration is really easy and the web portal is self-explanatory."
"The Global WAF has saved us more than one time from unwanted traffic."
"The user interface is very easy to work with."
"It is an easy-to-use, user-friendly interface, and you can set up a new VIP in a couple of minutes."
"We are most impressed with the ease of use and great support."
"The most valuable feature is the load balancing and allowing for high availability of our web services."
"Most important for us that it makes sure that the load is distributed and that we always have access to the end servers."
"With basic network knowledge, our required system functionality can be configured and maintained.​"
"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 user interface precludes need to be well versed with Linux IPVS command line. This make it easy for junior team members to participate in managing load balancing needs."
"We now get notifications when pool members go down, and we eliminate our downtime by not sending traffic to downed pool members.​"
"The support we have received from Loadbalancer.org has been good."
"The connection that this solution helps our servers maintain has been most useful."
"The performance is good."
 

Cons

"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."
"The product is really good as-is out of the box. If there is one thing I would change is to have the license file not be coupled with the MAC address of the device. This is actually not really useful in a virtual environment where if you have a single VM with KEMP LoadMaster and you have not set up static MAC Address, if you, for example, recreate the VM and just load the disk file on a new VM it will get new MAC address and the NLB will not work as it will not see a proper license."
"In the next release, they can introduce 360 views in the same dashboard to make it easier for users to view. The graphical information should be displayed on the dashboard."
"The only thing I have struggled with is setting up automatic backups."
"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?"
"UI is very basic and unattractive."
"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."
"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."
"I would like it if Loadbalancer had the ability to make rules for specific shared bots."
"We could enhance the security aspects of the load balancer."
"There is room for improvement in Loadbalancer.org in certain areas."
"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."
"It doesn't have the bonding capability feature."
"An area for improvement in Loadbalancer.org is that sometimes it works fine, but sometimes, it has issues. The setup for Loadbalancer.org is also complex, so that's another area for improvement."
"The interface from Loadbalancer.org should be improved."
"​The automatic refresh of the System Overview webpage: It sometimes has an extra webpage reload (after a change) before you see it is executed. This can be confusing."
 

Pricing and Cost Advice

"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.​"
"Currently, no cost is involved with a virtual load balancer. They have used open source. We did not pay for software. We paid for the expertise. We are only paying the consulting charges, which are very reasonable, that is, around a thousand dollars."
"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."
"This is a cost-efficient product."
"The price of the solution is cheap."
"Licensing is yearly and I am going to guess that it is CAN $2000.00."
"The Kemp LoadMaster is a tremendous value."
"It has a great price for the solution they offer."
"They're not the cheapest, not the most expensive, but I think value-wise, they're 100%."
"The costs associated with Loadbalancer.org depends on the technology. For some, we need to pay, but others are open, so they're free."
"For now, it's stable."
"It's worth the cost. It's not cheap, but it's a good solution. If you're looking for a good solution, this is a good solution. Is it cheap? No. Is it worth the money? Yes, I think it is."
"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."
"These guys make their pricing scheme really easy.​"
"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."
"It is inexpensive, and even their “unlimited” version, the VA MAX is still far cheaper than competitors."

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.
