Case Study: TDC Group achieves 400% rating-and-billing capacity boost and faster cash flow with Oracle Exadata, Oracle ZFS, and Oracle SPARC

TDC Accelerates Cash Flow with a 400% Boost to Rating-and-Billing Capacity

TDC A/S, a leading Danish telecommunications and Pay‑TV provider, needed to modernize its legacy mobile‑billing platform to handle massive growth in GPRS/3G/LTE data and social‑media–driven traffic, speed up rating‑and‑billing to accelerate cash flow, improve online self‑service responsiveness, and reduce the storage footprint and operational overhead.

TDC deployed Oracle Exadata, Oracle ZFS Storage Appliance, and SPARC T4 servers running Oracle Solaris, migrating more than 70 TB in a single weekend and going live in 55 hours. The new platform delivered a 400% increase in rating capacity (300% at peak), reduced bill‑cycle runtime by 30%, cut monthly report time from 24 hours to as few as 15 minutes, improved online response times by 30%, halved certain IT management tasks, and reduced storage needs by about 50% through Oracle Advanced Compression—together dramatically speeding billing, improving customer experience, and accelerating cash flow.
