Case Study: KKBOX achieves 30% lower cloud costs, halved streaming latency and near‑100% uptime with Google Cloud Platform

KKBOX Leading Taiwan and Asia-Pacific digital music platform delivers billions of music streams yearly

KKBOX, founded in Taiwan in 2005, is one of Asia’s leading music‑streaming platforms with 45 million tracks and over 10 million members across Taiwan, Hong Kong, Japan, Singapore and Malaysia. As the service expanded, on‑premises storage and an incumbent cloud provider caused reliability and performance problems—especially for live events and pan‑Asian listeners—producing high latency (50–60 ms) and capacity challenges.

KKBOX migrated core services to Google Cloud (Taiwan region), using Compute Engine, Cloud CDN, Cloud Storage and BigQuery, while adopting G Suite for collaboration. The move cut streaming latency to about 30 ms, delivered near‑100% uptime, reduced cloud infrastructure costs by ~30% and system administration time by ~10%, and supported scalable pan‑Asian operations and future initiatives like Kubernetes and AI‑driven recommendations.
