Case Study: International Financial Services Provider achieves global private-cloud scale and bank-grade security with Nuage Networks

Centuries Young Bank readies for another century of progress

The customer, International Financial Services Provider, is a centuries‑old bank that needed to modernize its infrastructure to become the world’s “Go‑To” bank. Faced with requirements to deliver an integrated online presence, unify six large datacenters, support multiple cloud management systems, hypervisors and bare‑metal servers, scale to many virtual machines, provide high elasticity for demand spikes, and meet strict security and compliance mandates, the bank moved to a private cloud architecture and engaged Nuage Networks, using Nuage Networks Virtualized Services Platform (VSP) and the 7850 Virtualized Services Gateway (VSG), to provide an SDN overlay and unified fabric.

Nuage Networks implemented VSP as an overlay across the Bank’s OpenStack‑orchestrated private cloud, with the 7850 VSG as the tenant gateway, turning special‑purpose hardware functions into software‑defined services (distributed switch, router, firewall), enabling stretched subnets across six datacenters and multi‑hypervisor/bare‑metal support. The solution delivered global workload portability, automated responses and improved cost efficiency, bank‑grade, VM‑level “Zero Trust” security, and the ability to absorb demand spikes; Nuage Networks’ design supports a projected 300% increase in supported virtual machines over three years while unifying operations and improving responsiveness.
