I have a client who currently has two WAN links through different providers. One Link is L3 MPLS, and the other Link is Primary Internet. The
proiver how provides MPLS is also providing backup Internet Link.
Client is moving to a new building which is in the same city and have Microwave Ethernet Access between the new building and the old building
since the users will be migrated gradually. User access most of the main applications via MPLS to the Cloud provider and in case if the MPLS goes down then the Internet based VPN will be used.
The problem is that the MPLS is ready in the new building, but the Primary Internet will not be available until a few months. All their critical
servers are running on the DMZ segment in the old building which we need to migrate to the new building.
Customer doesn't want to take a risk to cut-over to a MPLS in the new building without the Internet backup for external users to reach the servers on the DMZ in case if the MPLS goes down.
Since both the buildings are connected over the Microwave, we were thinking of moving the servers in the new building and continue to have internal and external users to use the existing MPLS and the Internet in the old building.
The risk is that we will be exposing outside users to our internal network when they will be coming over the MPLS and or Internet in the old building and then microwave link to the new building for the resources.
Any other idea besides taking risk with a solo MPLS link in the new building or not to move servers in the new building until both MPLS and Internet Links are available in the new building.
Thanks
