CASE STUDY
Award-Winning Data Platform Modernization: Telecom Giant Migrates to Snowflake on AWS
Introduction
For large telecommunications providers, the challenge of managing and extracting value from petabytes of data is a constant reality. Traditional on-premises data platforms often struggle to keep pace with this demand, facing limitations in scalability as data consumption surges, complexities in integrating with third-party data sources, and difficulties in providing timely, actionable reporting, not to mention the foundational requirements for AI-driven analytics.
This case study showcases how Hoonartek partnered with a major Indonesian telecom company to address the limitations of their on-premises data platform. By migrating to AWS-hosted Snowflake, the client achieved significant improvements in scalability, reporting availability, and cost efficiency, demonstrating the transformative power of strategic data modernization.
About the Client
Our client, a leading telecommunications provider in Indonesia, serves over 58.5 million subscribers with extensive 4G and 5G coverage, reaching more than 96% of the population. This significant market presence reflects the company’s commitment to providing robust connectivity across the archipelago. With a vision to be the #1 Converged Operator in Indonesia, the client aims to simplify and enhance digital experiences for its customers. Their achievements are underscored by industry recognition, including awards such as “Best Mobile Network Operator” and “Outstanding Customer Service,” highlighting their dedication to both network excellence and customer satisfaction.

The Business Challenge(s)​
The client’s Data Governance and Architecture team, responsible for architecting and leading enterprise data platforms, faced significant challenges with their on-premise Legacy Data Platform. Specifically, they sought to modernize their analytics infrastructure to achieve:
- Enhanced Scalability: The existing platform struggled to accommodate the growing volume of data and increasing demand for real-time analytics.
- Improved Reporting Availability: Business users required faster access to critical reports to support timely decision-making.
- Data Consolidation: The client aimed to consolidate disparate data sources onto a single, unified platform for streamlined data management and analysis.
- Operational Efficiency: The on-premise platform incurred substantial operational costs and required extensive maintenance.
- Cloud Adoption: The client sought to leverage the scalability and cost-effectiveness of cloud-based solutions.
Therefore, the “Analytics Data Platform Modernization Project” was initiated to migrate their petabyte-scale data platform from on-premise to a cloud-hosted environment, specifically AWS with Snowflake, to fully utilize the cloud and analytics platform key features.
