In the telecommunications sector's ongoing evolution, companies like Play, Poland's largest mobile operator, are modernizing their operations using the Elastic Stack to centralize and enhance data analysis. Despite facing challenges with legacy multi-vendor infrastructures and siloed information, Play has implemented a data-driven approach to optimize its operations. By adopting Elastic Stack, Play has created a unified data management and analysis system that integrates various data domains, allowing for faster problem resolution and new analytical possibilities. This approach enables automated incident detection and anomaly analysis through machine learning, reducing the mean time to resolution and enhancing network quality. The system's ability to overlay geospatial data, such as weather conditions, further refines their analysis and operational efficiency. This transformation has empowered Play's operations team to swiftly identify and address issues, significantly improving their service response time and infrastructure management.
