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

"When the templates are used, there is not much left to configure and they just work!"

"Simple to install with good documentation."

"Failover is seamless and our services are rock solid."

"The feature that allows us to easily disconnect a server when we need and bring back online is the most valuable. It's a click of a button. This allows us to keep all systems up. We can then run updates, perform reboots whatever we need to one of the servers without taking production down."

"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."

"Edge Security Pack is valuable because of the way it separates between critical infrastructure and the public internet."

"Managing and maintaining multiple servers is done in a single place."

"I like the way this solution handles multiple SSLs in different domains while still load balancing."

More Kemp LoadMaster pros

"The SSL Layer 7 load balancing is valuable."

"The most valuable features of Loadbalancer.org are related to its load balancing capabilities."

"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 performance is good."

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

"We now get notifications when pool members go down, and we eliminate our downtime by not sending traffic to downed pool members."

"The features I find valuable in this solution are the ease of managing the logs on the WAFs, the ease to identify break-in attempts into the network, the front-end firewall, and a more specific firewall."

"Most important for us that it makes sure that the load is distributed and that we always have access to the end servers."

More Loadbalancer.org pros

Cons

"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."

"When we go serverless, we may again have to revisit this because the configuration needs to be changed. With this change, we can run into a lot of other configurations that we haven't got into, which involve additional expenses. It would be challenging to convince management to buy at that price point. It would be a balancing act of justifying that expense and the value, that is, how it is going to save a bit of time and make our platform secure. It can have better configuration ability. A lot of iterations happen when we have multiple servers pointing to the same domain. If we do not orchestrate carefully, it gets into a loop, which takes away the precious time of the user who is trying to subscribe to a service. It takes a little longer time to realize services as well as web pages."

"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."

"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."

"It lacks an officially supported, well-written SCOM Management Pack."

"UI is very basic and unattractive."

"I definitely think that the WAF can be improved."

"Certificate installations could be simplified and modernized, and allowed to be monitored for expirations/issues."

More Kemp LoadMaster cons

"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."

"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."

"The interface from Loadbalancer.org should be improved."

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

"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."

"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."

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

More Loadbalancer.org cons

Pricing and Cost Advice

"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."

"The price of the solution is cheap."

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

"The price is lower than other options."

"The pricing is alright and we pay a monthly licensing fee"

"It has a very attractive ratio of price/performance."

"I have control on the licensing and all the prices since I work for a partner."

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

More Kemp LoadMaster pricing and cost advice

"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."

"Loadbalancer.org is based on open-source products, but it requires money for support and other activities."

"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."

"These guys make their pricing scheme really easy."

"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%."

"For now, it's stable."

"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
