What is our primary use case?
Our company e-mail and mobile communication system, which is based on Exchange Servers, needed load-balancing and security. After a few discussions with resellers and external consultants, we decided on the Kemp Load Balancer solution.
Our installation is a virtual Kemp Load Balancer based on VMware. We have configured four Exchange Servers in a DAG configuration and we have been very satisfied since it was installed. In the future, we would like to map further services via the Kemp.
How has it helped my organization?
For us and our e-mail and mobile communication system, the load-balancing and security features are very well-suited.
From the installation and configuration to the daily routine, Kemp is great. Importing and defining the rules for the communication systems was quick and easy. Various services and ports are configured for our e-mail and mobile communication system, and we configured some Access Control Lists (ACLs) and the Web Application Firewall (WAF).
After the configuration was complete, we found that we can still use Kemp for more services.
What is most valuable?
The most valuable feature is that load-balancing, as Kemp helps to maintain the uptime from the e-mail servers.
If we have or need a maintenance window for one of the other e-mail servers, Kemp will still deliver your e-mail traffic to the other server. It just works.
It is easy to apply windows updates to your Exchange environment, and using the Kemp Load Balancer made it easier to handle.
Another great feature is the ability to use the Kemp Load Balancer virtual appliance in our VMware environment.
What needs improvement?
In the web interface, there are a lot of settings in the different menus and it would be helpful if there were an interactive help system or tooltips to help the administrators find and configure the right settings.
The configuration of "standard" services is quite easy but when you configure more advanced settings, it's no longer easy and can be challenging. The Kemp Load Balancer is a very good product out of the VMware ISO (Box).
Sometimes, you feel years back in the web interface but it's just cosmetic.
For how long have I used the solution?
We have been using Kemp LoadMaster for nearly two years.
What do I think about the stability of the solution?
Stability-wise, this is a great product.
What do I think about the scalability of the solution?
The scalability is great.
How are customer service and technical support?
We had contact with customer service/technical support for the license renewal and i can say the contact was very helpful and friendly, just great. Until now all our questions have been answered and resolved by the vendor.
Which solution did I use previously and why did I switch?
We haven't tried any other solution.
How was the initial setup?
The initial setup was straightforward.
What about the implementation team?
It was a mix between in-house and vendor team, and the expertise of the vendor team is awesome.
What was our ROI?
There is no ROI. It is for security reasons that we decided to use the Kemp Load Balancer solution. We no longer wanted the traffic to go directly to the Exchange servers.
What's my experience with pricing, setup cost, and licensing?
The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money.
Which other solutions did I evaluate?
We did not evaluate other products. We thought about some other solutions in theory but ultimately decided in favor of Kemp.
What other advice do I have?
Its a Kemp it works great.
Which deployment model are you using for this solution?
