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 feature I find most valuable is load balancing with different algorithms."

"Load-balancing is a great feature that is very easy to configure and it is always working fine."

"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."

"The security features, load balancing, built-in templates, and the easy to implement virtual IPs are great."

"With Kemp 360 Central, our customers get a nice overview of their Kemp products and an easy way to upgrade firmware on all devices from a single interface."

"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."

"Persistence is very valuable. This holds the connection information of the source and that connection is important to RDP and our APO calls. The connection has to be persisted to the original source to operate properly. We also use the subsections for sub-services to create services inside our services for our API resources, this is most awesome. We would not be able to do this without Kemp and offer this type of sub-service to route based on an API instance. It routes the traffic properly based on the sub-service type."

More Kemp LoadMaster pros

"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 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."

"With basic network knowledge, our required system functionality can be configured and maintained."

"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."

"The connection that this solution helps our servers maintain has been most useful."

"Load balancing helps us distribute both incoming and outgoing data loads evenly among the servers, preventing overload on a single server."

"Loadbalancer.org is less complex than Citrix."

More Loadbalancer.org pros

Cons

"I really don't like the way the logs are presented in the software."

"Although Kemp is very user-friendly, it lacks a more custom configuration."

"UI is very basic and unattractive."

"The ability to see live traffic is not great and can be improved."

"In the next release, Kemp should include the ability for LoadMaster to create different DNS record types."

"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."

"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."

"They need to improve the UI environment. Currently, it's hard to navigate and use product."

More Kemp LoadMaster cons

"The solution can be a bit pricey."

"It doesn't have the bonding capability feature."

"I would like a notification when a new version of the software is available. They told me to sign up for their newsletter, but I have not received any notification for a newer software version."

"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."

"I'd like to see scalability improved; it can be costly."

"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."

"Originally we had some stability issues with it, so they replaced it with a new box and it's fine."

"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."

More Loadbalancer.org cons

Pricing and Cost Advice

"This product has good value and features for the money."

"The setup cost and pricing plan is reasonable and will ultimately give you a worthy return."

"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."

"The price is great and the value is definitely there."

"They have multiple tiers of licensing and you can upgrade it easily."

"Setup is easy, the cost is affordable, and the licensing is quick and simple."

"The price is lower than other options."

"Licensing is yearly and I am going to guess that it is CAN $2000.00."

More Kemp LoadMaster pricing and cost advice

"The solution requires an annual support license of $2,780 for four systems or $695 a year per unit for support not including the units."

"It filled a requirement for our project, and it did so at lesser cost than their competitors."

"The costs associated with Loadbalancer.org depends on the technology. For some, we need to pay, but others are open, so they're free."

"It was easy to upgrade the license for unlimited clusters and servers. Pricing is fair."

"It is inexpensive, and even their “unlimited” version, the VA MAX is still far cheaper than competitors."

"They're not the cheapest, not the most expensive, but I think value-wise, they're 100%."

"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."

"I think it’s very affordable."

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.

Reviews from Real Users

“Loadbalancer.org is less complex than Citrix. In some cases, our customers do not have an engineer on staff who can support this device. These customers have a large number of Linux engineers but don't have the money. We suggested using Loadbalancer.org and other open-source tools. Many customers are of different sizes and have different budgets. Loadbalancer.org has everything that is needed.” - Artem M., System Engineer at CROC

“We use Loadbalancer for balancing loads in our main application. Loadbalancer is easy to use. It performs well, with low latency.” - Walid M., Network and Security Engineer at a logistics company
