How to move audit log mailbox in Exchange Server 2010/2013/2016/2019? I recommend you to move…
Before installing a second Exchange Server, we like to have a virtual load balancer in front of it. You don’t have to use a virtual load balancer and can use round-robin DNS as a technique to load balance. Using a dedicated load balancer will give more insight into what’s happening and distribute the load smarter on the Exchange Servers. In this article, you will learn how to install Kemp virtual load balancer on VMware ESXi.

Kemp FREE LoadMaster load balancer
The Kemp Free LoadMaster is a version of the Kemp load balancers that runs as a virtual machine within a hypervisor and can provide all the features and functions of a hardware-based LoadMaster. It’s free forever, which is excellent.
The limitation is the 20 Mbps throughput, and there is no technical support. Do you want to get technical support? Try the 30-day trial. You can easily upgrade with a license from trial to paid license.
Bear in mind that if you want to upgrade from the free version to a trial or paid license, you have to back up the configuration and install a new instance of the load balancer. After that, you can restore the configuration. That’s because the trial/paid instance and the free instance use different images.
Compare Free LoadMaster vs. Paid.
