Case Study: KDDI Corporation achieves 12x faster mobile-user authentication, ensures business continuity, and reduces TCO with Oracle SuperCluster

KDDI Improves Mobile User Authentication System Performance by 12x, Ensures Business Continuity, and Reduces Total Cost of Ownership

KDDI Corporation, a major Japanese telecom serving over 40 million mobile subscribers, faced performance, cost, and availability pressures from its aging mobile-user authentication infrastructure of 40 legacy servers. The company needed to consolidate systems to handle explosive mobile traffic growth, ensure continuous service (especially during emergencies), simplify IT management, and reduce total cost of ownership.

KDDI deployed four Oracle SuperCluster T5-8 engineered systems (with Oracle Solaris and Oracle Solaris Cluster), cutting the server count from 40 to 4 and completing rollout in six months. The new platform boosted authentication performance 12x, eliminated single points of failure with built‑in redundancy and multisite clustering, reduced data-center space by 85% and energy use by 70%, lowered licensing/maintenance costs, and sped delivery of new services through simplified operations and faster patching.
