*** Please see network diagram ***
We currently have 4 location (3 in the US, and data center in India)
All locations are currently connected using MPLS (3 Mb) but the contract is ending soon
A. (Data Center in the US) has a Sophos UTM (Firewall) with a VPN tunnel connected to D(India data center)
and has fiber (150/150) and cable connection (16/3)
B. (Corporate) currently has a cable connection (75/15)
C. (Remote Location) currently has a cable connection (100/7)
D. (India Data Center) "hosted" our ERP program server and email server
Other then "private networks" (ex: MPLS) and VPN tunnels, via internet connections, are there kind of emerging technologies for WAN connectively?
At corporate(B), we want to have "high availability" to the India data center (D). As the diagram shows, if US data center (A) loses connective, then corporate (B) would also not be able to connect to our ERP or email. Can this be done with by adding something other then a firewall at corporate (B). Note: All internet traffic flows thru US data center(A), for monitoring, which is the reason right now for not connecting corporate (B) directly to India data center (D) via VPN tunnel
Would a mutli - WAN router work for any of this?
