PeterForster - PeerSpot reviewer
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.
Richard Polyak - PeerSpot reviewer
Easy to set up and has good integration into the host environment but needs better third party integration
I'm not sure which version number we are on. It's one of the latest, I assume. We don't run the latest. We usually are either one or two versions behind. It is something we are exploring. We do have use cases and it will compete against our existing product line. That would have to go in the second half of this year. Right now, it's more of a comparison of how we use it right now. We don't use it really in production. We are going to definitely explore it and do our comparison and more in-depth analysis of the product and compare it against our existing product line. I'd advise potential users to do a very in-depth analysis of the products in comparison. And don't just look at the cover of it - really look into the detailed backend support infrastructure and if it can be implemented the way you need it to be. I'd rate the solution five out of ten. It's not a fully mature product.

Quotes from Members

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

Pros

"LoadMaster is easy to deploy and understand."
"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."
"I like that this is a Network Load Balancer that can be used practically with any application in the backend. They have how-to guides on how to set up Kemp NLB with Exchange, but you can use it as well for Sharepoint, RDS, or any other back end server."
"The most valuable feature so far has been the high-availability options that allowed us to add an additional Kemp LoadMaster VLM virtual appliance into our VMware vSphere environment, to provide failover for our existing LoadMaster."
"We needed a Microsoft Threat Management Gateway server replacement solution for a customer and were impressed with the simplified deployment of the Kemp LoadMasters."
"The DNS Load Balancer makes it so that I don't have to worry about site failures."
"Edge Security Pack is valuable because of the way it separates between critical infrastructure and the public internet."
"The configuration is really easy and the web portal is self-explanatory."
"What's most valuable in Avi Networks Software Load Balancer is its deployment capability, the ability to deploy in a dispersed service, with the service engines that can disperse and have a single control plane that can control the load balancing services across any available platform, wherever needed. The analytics of Avi Networks Software Load Balancer and flexibility of deployment are its most valuable features and the reasons why many people buy it."
"The most valuable feature of the solution for my organization is its UI since it allows us to see the clusters while providing a very specific and good overall understanding."
"The interface and software features are the most valuable aspects of this solution."
"The friendly user interface is valuable."
"The WAF - the web application firewall itself - is great."
"The solution is stable."
"The solution has simplified our network infrastructure management."
"Its visibility and login mechanism are the best parts. In addition to the great visibility it has a great dashboard and an easy to configure graphic user interface, a beautiful GUI."
 

Cons

"Some documentation is out of date versus the new version, and things have been moved​."
"There are some challenges with updates on certain models that don't have a few features."
"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."
"UI is very basic and unattractive."
"Hardware version needs a dual power solution."
"It would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."
"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."
"SNMP and/or RESTCONF management, in order to collect many counters, for plotting in a central application need to be improved."
"Avi Networks Software Load Balancer needs to improve its documentation."
"In terms of improvement, the pricing and documentation need improvement. We have had problems getting the documents."
"IDS and IPS sites need to be more progressive."
"The network analytics and monitoring features are not effective."
"The initial setup is a bit complex."
"One struggle with Avi Networks Software Load Balancer is its integration with other VMware products. Integration could be improved in the solution so that you have a more unified control plane with it and other data center security and networking products that VMware sells. There has been a bit of a lag on the roadmap of new features that have come out there recently, but better interoperability with the hyperscale environments such as the AWS, Azure, GCPs of the world, and simpler deployment and interoperability with those existing tools, are areas that are receiving attention and could use additional attention today. These are the areas for improvement in Avi Networks Software Load Balancer."
"It doesn't match the development structure or user community of our existing product. It pales in comparison to that."
"I did not go with it because their APM module is a different product altogether. It's a common thing that companies do. They sell something and then they add on top of it as a different product. It is a type of marketing strategy. But when it comes to the overall management, it takes a lot of time to really look into it."
 

Pricing and Cost Advice

"This is a cost-efficient product."
"Setup is easy, the cost is affordable, and the licensing is quick and simple."
"The price of the solution is cheap."
"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."
"Less expensive than Citrix."
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"The pricing is alright and we pay a monthly licensing fee"
"The Kemp LoadMaster is a tremendous value."
"The tool is expensive."
"I rate the solution price a four to five on a scale of one to ten, where one is low, and ten is high, since it is an affordable tool."
"The licensing costs for Avi Networks Software Load Balancer are really variable. The product can be sold from a bandwidth utilization perspective. It can be sold from a per CPU perspective, depending on if you're looking at on-premises or hyperscale environments. Licensing costs vary quite a bit if you're familiar with the AWS Calculator, where you can see that it can widely vary per licensing model. On a scale of one to five, with one being not very good value for the money and five being great, I would rate the pricing for Avi Networks Software Load Balancer a five because its pricing is extremely competitive. Not all features are included with the license, for example, there's single licensing."
"With Avi Networks, you can buy a 10-Gig license and, if your primary data center goes down, in the flick of a switch you can move that license to your backup data center and it will generate the traffic... there are a lot of cost-effective measures."
