Axiata, a leading Asian telecommunications conglomerate, manages hundreds of thousands of cell towers that require ongoing hardware and software updates to maintain service quality. Facing challenges in processing proprietary data and lacking real-time insights, Axiata partnered with Broscorp to develop a fully automated ETL platform. This system integrates data from telnet protocols into a scalable data warehouse using Apache Nifi and ClickHouse, while Grafana dashboards provide the operations team with real-time monitoring and anomaly alerts. Broscorp's solution empowered Axiata's management to precisely track the impact of hardware changes, simplifying decision-making and enhancing network performance without additional maintenance. This collaboration exemplifies data engineering expertise transforming telecom operations into data-driven processes.
