Consider and plan for disaster recovery (DR) by designing the solution to failover to another datacenter when any outage on the main site occurs.Distributed File System (DFS) should be used to provide HA for file stores. Configure HA for File Servers which store meeting content and address book information. Consider and plan for High Availability (HA) by deploying multiple instances of Front end servers, Edge servers, Director, Mediation, and Video interop Servers.Make sure you consider whether high availability is required before ordering licenses. Both provide the same user features, but the standard edition does not provide high availability and also has a limitation on number of users it can host. Skype for Business is available in standard and enterprise editions.You could plan for initial on premise deployment and the move into hybrid mode or completely move online in the cloud later as needs grow and change.
