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.

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

"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."

"The base feature of Kemp LoadMaster load balancing ticks all the boxes but the most valuable features would be the security features Intrusion Prevention (IPS) and Web Application Firewall (WAF)."

"The configuration is really easy and the web portal is self-explanatory."

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

"The DNS Load Balancer makes it so that I don't have to worry about site failures."

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

"We are most impressed with the ease of use and great support."

"When you configure the listening services, you can implement a lot of security features like the Edge Security Pack that intercepts the requests and processes those before they are sent to the real servers."

More Kemp LoadMaster pros

"The friendly user interface is valuable."

"The solution has simplified our network infrastructure management."

"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."

"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."

"The interface and software features are the most valuable aspects of this solution."

"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 solution is stable."

"The WAF - the web application firewall itself - is great."

Cons

"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."

"Hardware version needs a dual power solution."

"Some documentation is out of date versus the new version, and things have been moved."

"We have experienced at least one problem with stability, although it was fixed with an upgrade."

"The auth website of ESP is really lacking. It’s not responsive (mobile friendly) and the procedure of changing the website is difficult. We tend to avoid using pre-auth for that reason."

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

"I would like to see more automation and control of overactive and inactive resources. If I could schedule these around our updates then it would be all automated. I would like to set up an automated script to coincide with the scripts I use to update resources and servers."

"To make it a perfect ten out of ten it would need better connection logging. If there is an active connection, that there is better logging. It should also have better management monitoring tools."

More Kemp LoadMaster cons

"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."

"In terms of improvement, the pricing and documentation need improvement. We have had problems getting the documents."

"Avi Networks Software Load Balancer needs to improve its documentation."

"The network analytics and monitoring features are not effective."

"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."

"IDS and IPS sites need to be more progressive."

"The initial setup is a bit complex."

Pricing and Cost Advice

"The price of the solution is cheap."

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

"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."

"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."

"It is well-priced and licensing is very flexible."

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

"The price is lower than other options."

"The product definitely provides what the organization needs and its cost is reasonable considering the value it brings."

More Kemp LoadMaster pricing and cost advice

"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."

"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 tool is expensive."
