Case Study: DNA achieves always-on, scalable service delivery with Citrix NetScaler SDX

Telecommunications leader relies on Citrix NetScaler SDX for always-on services

DNA Ltd., Finland’s largest cable operator and leading pay-TV provider serving nearly 4 million customers, needed to replace aging load‑balancing equipment to support ongoing growth. The company required greater reliability, scalability and flexibility to maintain high‑quality voice, data and television services across a wide geographic area.

DNA deployed Citrix NetScaler SDX with geographically decentralized nodes across two datacenters, Layer‑3 HA over an MPLS backbone and dynamic BGP routing, enabling independent, isolated instances for multitenancy. The new solution delivered superior failover, increased security and control, cost‑effective scaling and higher uptime for millions of customers while laying the groundwork to consolidate and expand services as the business grows.
