What is our primary use case?
We use the Kemp Loadmaster to load-balance enterprise-wide applications that require high-availability. We also wanted to make sure the performance and throughput meet the needs of the usage of our applications.
These applications include Microsoft Exchange, Microsoft Active Directory Federation Services (ADFS), Microsoft SharePoint (2010, 2013), file sharing servers, multiple public-facing websites, multiple internal websites, on-premise IT Service Management applications, and others.
The LoadMaster handles both production and development environments for these applications.
How has it helped my organization?
The Kemp LoadMaster was very easy to deploy and we initially deployed without needing much tech support help. The management is very intuitive and can easily be used by techs without needing extensive training to use.
The LoadMaster met all of the features and performance we were looking for at a very affordable price. We were also looking to lessen the real estate rack space in our data centers and really wanted a virtual solution that will work with our Hyper-V environment.
Having a Hyper-V image that we easily deployed to multiple Hyper-V clusters allowed us to achieve high availability with the LoadMaster.
What is most valuable?
The templates provided by Kemp for well-known applications like Exchange and SharePoint make these applications very easy to deploy. When the templates are used, there is not much left to configure and they just work!
I have used and evaluated templates from other load balancing vendors, but still required extra help from a technician just to make the application work correctly. This is a little frustrating sometimes since you would think that the template should just work.
I have not had any issues with any of the LoadMaster templates at all.
What needs improvement?
Out of the box, the LoadMaster provides real-time statistics regarding connections to the real servers, as well as to the virtual services. We see the number of connections in the last 5/30/60 minutes, and current active connections as well. However, it would be nice if we were able to drill in further to see the actual IP addresses that made up these connections, whether they were coming from the internet or internal, and possibly the option to disconnect certain active connections.
The historical graphs showing CPU metrics and the network is useful, as well. It would be nice if the historical metrics were easily exportable from the interface.
For how long have I used the solution?
We have been using Kemp LoadMaster for the past nine years. This was eight years using the hardware-based LoadMaster, and less than a year on the virtual LoadMaster platform.
What do I think about the stability of the solution?
We like the stability of the LoadMaster setup on high-availability, running two separate Hyper-V clusters. We have tested HA failover of the virtual devices a few times now and failover worked perfectly each time.
What do I think about the scalability of the solution?
Since we are using virtual LoadMasters, we are certain that we can easily scale when needed without needing extra hardware.
How are customer service and technical support?
Kemp customer service is excellent. When I had submitted a ticket for questions I had, the response was almost immediate and they made sure to always follow up with me just to check that everything was to our satisfaction.
Which solution did I use previously and why did I switch?
We switched from a prior solution since the LoadMaster provided the features, performance and throughput that we required for a more affordable price point.
How was the initial setup?
The initial setup is very easy since we were provided an image for our hypervisor. Technical documentation was provided and it was very easy to follow and initially configure without needing extra technical help.
What about the implementation team?
What was our ROI?
Our ROI on the Kemp LoadMaster is very positive.
What's my experience with pricing, setup cost, and licensing?
It is well-priced and licensing is very flexible.
Which other solutions did I evaluate?
We looked at Radware and F5.
What other advice do I have?
The LoadMaster is very easy to set up, configure, and manage. We have been using it for almost 10 years and are still very happy with this solution.
