How to add exchange and dc servers in the cloud to fail over when onsite servers go down

I have two domain controllers and one exchange server in a physical server environment on site.  I would like to set up some servers in the cloud to take over if one or all of the servers onsite fail.  Can anyone recommend a set up for this?  I need a procedure and a path for how to set up and implement this.  My exchange server is exchange 2010 standard running on windows server 2008r2 standard.  My domain controllers are on windows 2008 r2 enterprise.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The only way I know of to accomplish this is to use a backup appliance such as Datto (not recommending Datto and there are others).  These backup your servers on site, allow you to spin up VM's on their appliance should the regular servers go off line, and should the building be destroyed allow you to spin up VM's of your servers from "a few minutes ago" in their data center, aka, "the cloud".

Mail can be sent to an internet "backup mail server", many of which are free, via a second MX record with a lower priority.  Should your server go off line mail will go there until your mail server comes back on line.  Search for "backup MX" or "backup mail server"
