Case Study: Telkomsel achieves 56% infrastructure cost reduction and 2x faster deployment with Cloudera

Transforming Data into a Strategic Asset with an Enhanced IT Platform

Telkomsel, Indonesia’s largest cellular operator with over 170 million subscribers and 233,000 base stations, faced explosive data growth—up to 50 TB per day and 20% year‑over‑year—straining its legacy IT platform and increasing costs. To stay competitive and meet rising customer expectations, the company needed a scalable, integrated data architecture to lower total cost of ownership and accelerate solution delivery.

Working with Cloudera and partner Wipro, Telkomsel implemented a Cloudera Data Platform data lakehouse with Apache NiFi pipelines and the Cloudera Data Science Workbench, supported by an internal Centre of Excellence. The modern platform halved infrastructure spend variability and delivered major efficiency gains—saving up to IDR 10 billion annually, cutting infrastructure expenses by 56%, reducing solution delivery times by 60%, doubling deployment speed, and empowering teams to innovate faster without vendor lock‑in.
