Telco Unlocks Real-Time Analytics on Snowflake
A tier-1 telco migrated 15+ legacy data warehouses to Snowflake, enabling real-time network performance analytics and reducing reporting latency from hours to seconds.
The Challenge
The operator's fragmented analytics estate — spanning 15+ legacy on-premises data warehouses — was delivering reporting with 4–12 hour latency, preventing real-time network management decisions and creating significant data quality issues across teams.
Our Approach
Saints & Masters designed a unified Snowflake Data Cloud architecture, migrated and transformed 15 source systems using dbt, implemented real-time Kafka ingestion pipelines for network telemetry, and delivered a governed semantic layer accessible to 300+ analysts.
Outcomes & Results
- 15 legacy data warehouses consolidated into one platform
- Reporting latency reduced from hours to under 30 seconds
- 300+ analysts now working from a single governed data source
- Real-time network fault detection enabled for the first time
- 40% reduction in data infrastructure operational costs
