With multiple data centers (DCs) and a cloud production environment, bullet-proof connectivity and low-latency traffic forwarding is a mission critical must-have for the bank. Quite simply, all its systems and applications need to operate seamlessly together, with minimal risk and straight-through processing.
Connecting the bank’s HQ, DCs and disaster recovery sites in all its home markets, Telia Carrier’s (now Arelion's) high-capacity fiber backbone core solution features metro-optical fiber links for connectivity to local DCs.
Delivering the strict separation of geographically diverse networks needed to assure the high reliability and availability the bank needs, the solution incorporates Telia’s 100G-enabled wavelength services which deliver the L2/L3 protocol transparency requirements the bank needs to manage protocols such as CDP, Mac-Sec and MTU jumbo frames.
Internationally, Telia Carrier (now Arelion) provides the bank with high capacity Layer 2 links that connect its international sites in a point-to-multi-point topology that links dual main sites with DC and disaster recovery sites in each country the bank operates in. This approach enables the bank to create and control its own routing principles through Telia Carrier’s (now Arelion's) protected MPLS backbone.
A dedicated IP connection to Microsoft Azure provides the bank with the controlled, scalable and flexible private network connectivity it needs to its cloud services.
