What is our primary use case?
We use an on-premises Skype for Business Server VoIP service that utilizes the Kemp LoadMaster LM-2400 for service resiliency. This allows our three front-end servers to seamlessly support our service. We never miss a call and our chat service is always ready as a result.
Kemp has a pre-made virtual service profile that perfectly fits our use case so the initial setup is quite easy. We also have expanded the use of the LoadMaster to accommodate a number of ancillary services that also require resilience.
How has it helped my organization?
The Kemp LoadMaster is easy to set up, well documented, and very easy to maintain. It has done a flawless job supporting our Microsoft Skype for Business Server VoIP services, as well as expanding to cover a number of other services that require load balancing.
The LoadMaster has helped to keep our Voice over IP services in-house, which has produced tremendous savings versus hosting our services in the cloud. This has allowed us to devote our resources to other projects, increasing our overall effectiveness.
What is most valuable?
The load balancing features of the LoadMaster are the best we have used.
Failover is seamless and our services are rock solid. Kemp maintains a library of templates pre-configured for a number of services, including Microsoft Skype for Business Server. This makes configuring the virtual services very easy. It also makes it very easy to add additional virtual services as you find new use cases. The convenience of being able to download new or updated templates from Kemp's support site cannot be understated.
What needs improvement?
If I had to pick an area for improvement, I think it would be direct integration with the template library. At present, you need to download the templates from the Kemp support portal and then upload them onto the LoadMaster. 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.
For how long have I used the solution?
We first implemented our Kemp LoadMaster eight years ago when we launched a new VoIP project that required load balancing for enhanced reliability.
What do I think about the stability of the solution?
The stability is rock solid. We have only experienced one issue in eight years. Kemp support was all over it and got us back online in no time.
What do I think about the scalability of the solution?
For our organization, the LM-2400 is perfectly sized. I'm sure it has an upper limit but we have not gotten anywhere near it yet.
How are customer service and technical support?
Kemp tech support has been absolutely fantastic.
We have had one hardware issue, which over a span of eight years isn't bad at all, and one setup question. Both of these issues were handled quickly and to our satisfaction.
Which solution did I use previously and why did I switch?
Previously, we had been using a Barracuda load balancer. It was nice but the management was not as easy to use and it was not quite as reliable as we would have liked.
How was the initial setup?
The initial setup was very straightforward. The virtual service templates provided by Kemp make setup a snap!
What about the implementation team?
We used a vendor team but our assigned technician was not familiar with networking or load balancing. I ended up taking over the setup and it couldn't have been easier.
What's my experience with pricing, setup cost, and licensing?
The Kemp LoadMaster is a tremendous value. It works well and is easy to set up and to maintain.
Which other solutions did I evaluate?
Barracuda and F5 were evaluated as well. The performance and value were found to be much better with the Kemp LoadMaster.
What other advice do I have?
The Kemp LoadMaster just works. It is extraordinarily difficult to suggest any changes that might improve its feature set. Go with Kemp, you won't regret it!
