I am currently writing a specification for a national body that requires to connect a number of small data centres (<50) over the public internet. The data to be sent is 'not-for-us' data whereby data is received at centre A but needs to be processed by centres B and C therefore centre A must send some data to centre A and some to centre B. This could occour throughout the mesh.
I am resonably sure about the VPN protocols required (L2TP/IPSec) but am uncertain about the hardware to recommend. The data centres could be anything from a single computer processing the data stand alone to a fully fledged data centre with multiple computers fully networked.
I would be grateful for any thoughts on the hardware or software setup to specify as I must admit I'm currently a bit out of my depth.
