In Recovered Revenue
Company Information
T-Mobile is a leading telecommunications provider in the United States, known for its innovative approach to mobile connectivity and customer-first strategies. With a vast nationwide 5G network, T-Mobile offers wireless voice, messaging, and data services to millions of consumers and businesses. Committed to delivering high-speed, reliable, and affordable solutions, the company continues to disrupt the telecom industry with its focus on innovation, customer experience, and expanding digital access. T-Mobile’s mission centers around connecting people to what matters most, driving advancements in mobile technology, and providing superior services across various sectors.
The Challenge
A team within T-Mobile relied upon a legacy on-premises Oracle Database. As their volume of data grew, the legacy database proved unable to handle the business’s desired data-aggregation queries. These bottlenecks proved a perfect challenge for Snowflake’s highly scalable and performant Cloud Data Platform.
Our Approach
ProCogia migrated this team's legacy data from Oracle to Snowflake, applying custom ETL to meet the team's requirements such as parsing of unintelligible/numerical codes to human-readable names.
Amazon EMR was used for reading from Oracle DB to Snowflake due to limitations with Snowpark.
Numerous normalized Oracle tables were consolidated into a smaller set of denormalized Snowflake tables.
PII Data underwent anonymization processes within Snowflake's secure environment, ensuring enhanced data privacy and protection.
Daily QA counts were generated and displayed in a dashboard, so engineers and stakeholders could monitor daily/weekly/monthly data volume trends.
Architecture
Results
With the on-demand scalability of Snowflake, this team was able to run their queries in minutes rather than hours and days.
Better Security and maintenance with centralized auditing of user/role access.
The biggest success for business stakeholders was the enablement of large data aggregations for reverse billing, leading to the recovery of $2M in revenue.
Conclusion
In migrating from their legacy on-premises Oracle Database to Snowflake, this team immediately unblocked the scalability issues which had restricted them. This provided instant value in the ability to recover $2M in revenue. Once migrated to the Snowflake Data Platform, the benefits proved far beyond scalability and performance, as Snowflake’s access-control and data-sharing features streamlined the team’s data governance process.
