I have a customer who has recently merged with another business, across two sites. The current set up is that one site has a Server running Windows Server 2008 and the other just has a peer-to peer network with PCs running Windows 7, an iMAC and a NAS. Both sites currently have standard broadband, so typically 5 Mb/s download, 0.5Mb/s upload. Both sites currently have their own separate web domains.
What would EE experts recommend as the best solution to integrate the two sites, for file, calendar and contacts sharing and operate as a now single entity over a WAN?
I am reluctant to just set up VPNs into the Server site as this is likely to be too slow operationally, being constrained by the uplink speed of the site with the Server.
Cloud solutions such as Google Apps could work, but there is always the fundamental issue that file locking is not (cannot be?) implemented in such systems.
Any advice welcome.
