Total infrastructure hosting out-side the premises ???

HI Experts,

Currently I have about 45 Windows 7 clients on Windows Active Directory and Exchange environment. Also there will be about 20 IIS application servers and 10 database servers in house. Apart from this there will be file server and source controller too. This local network is a platform for .net software development process. ( I just need to give you an idea about the current bandwidth required)

I'm planning to move all these services to the reliable data center. (disaster recovery, security, etc)

What are key respect that I need to worry about  ?
What kind of bandwidth level do we need to run our all 45 windows clients in house with a remote data center  ?

Any helpful tips would be highly appreciated and thanks a lot !

I have the similar setup at the Data Center with 100MB redundant pipe.  From the Data center the storage synch onto another storage device at HQ via IP replication and SnapMirror technology.
Data Center itself should be extremelly safe place.  

So you have to worry about the downtime.  If the data center does tanks (natural disaster, power failure, user error, etc etc)  how much time do you need to switch clients over to HQ or another redundant location.  That downtime you need to describe in your contracts, say within 48 to 72 hours recovery.

Hope it helps just to give you an idea.

Thanks for the comments Tiras25, the thing is we are located in Asia Pacific and bandwidth cost here too much.

I'm thinking whether I can handle our in-house bandwidth requirement for 10Mbps point to point link from the collocated data center. Also I'm planing to think of a redundant ISP too.
