We use our devices as virtual load balancers for Exchange 2016, primarily.
We have two sites with two LMs at each site in clusters. We also use the devices as global DNS services and reverse proxy/authentication servers for our external users.
Our services are primarily Microsoft products being served. These include Exchange, SharePoint, CRM Dynamics, Skype, and ADFS. We are also looking at implementing websites in the future as required.
SSL offloading is enabled. Our devices are set up in the network as well as the DMZ.
