As a part of a DR plan i need to offer the business a solution for failover. They are currently running a Server 2008 domain, Exchange 2010 std and Terminal Services (2008). I have placed a few VMware options on the table as they are already virtualised but i would like to add a windows based replication to the pot but would like to confrim a few items.
Server 2008 (i am happy that a VPN and hosted DC would replicate AD)
Exchange 2010, for this to work in any redundant way would they need to look at upgrading from Std to Enterprise and what options would work over a VPN to a cloud solition (i am happy to put in a caluse for 100mb lease line if required)
DFS, this has been around for a while and just wanted a view on the replication, i also know i could offer somthing along the lines of branch cache.
