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 most beneficial function of using the ADC is to ensure this resiliency."
"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."
"The security features, load balancing, built-in templates, and the easy to implement virtual IPs are great."
"The most valuable feature is the load balancing and allowing for high availability of our web services."
"There is a simplicity to the setup and configuration."
"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."
"When the templates are used, there is not much left to configure and they just work!"
"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."
"Loadbalancer is easy to use. It performs well, with low latency."
"Load balancing helps us distribute both incoming and outgoing data loads evenly among the servers, preventing overload on a single server."
"Most important for us that it makes sure that the load is distributed and that we always have access to the end servers."
"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."
"The support we have received from Loadbalancer.org has been good."
"Loadbalancer.org is less complex than Citrix."
"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."
"The performance is good."
 

Cons

"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."
"It would be helpful if there were a way to incorporate tooltips on the fields so that we don't have to dig through documentation."
"There is room for improvement in the stability of the solution."
"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 really don't like the way the logs are presented in the software."
"Hardware version needs a dual power solution."
"The GUI is rather technical and complex, so it could be improved by making it simpler and more user-friendly."
"In the next release, Kemp should include the ability for LoadMaster to create different DNS record types."
"The solution can be a bit pricey."
"There are many features you can set in the backend of Loadbalancer. They should simplify the configuration. The administrator should be able to configure it more simply. How it is now, you can only configure it if you have a lot of experience."
"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."
"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."
"It would be great if there was a way to gain access to the graphing data, to create custom reports. If we had a way to use the graphing data, we could use it to present certain information to our client, such as the uptime status for their service."
"I would like it if Loadbalancer had the ability to make rules for specific shared bots."
"The interface from Loadbalancer.org should be improved."
"Originally we had some stability issues with it, so they replaced it with a new box and it's fine."
 

Pricing and Cost Advice

"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."
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"Less expensive than Citrix."
"The price is great and the value is definitely there."
"The pricing is alright and we pay a monthly licensing fee"
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"It is well-priced and licensing is very flexible."
"From a cost perspective, Kemp is very competitive and is not hard to justify by any means."
"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'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."
"We've got an unlimited license, which doesn't costs that much compared to other vendors, and we don't have to buy it again."
"For now, it's stable."
"Loadbalancer.org is based on open-source products, but it requires money for support and other activities."
"It filled a requirement for our project, and it did so at lesser cost than their competitors.​"
"It was easy to upgrade the license for unlimited clusters and servers. Pricing is fair."

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.
