D3L2: Why did we migrate to a Data Lakehouse on Delta Lake for T-Mobile Data Science and Analytics Team

T-Mobile's mission to build the nation's best 5G network drastically increased the number of monthly network projects planned and directly impacted the enterprise procurement and supply chain organizations. Like many enterprises, data at T-Mobile was spread between disparate, unintegrated and complex systems.
In this session, we will discuss the how and why we migrated from databases and data lakes to a data lakehouse on Delta Lake. Our lakehouse architecture allows reading and writing of data without blocking and scales out linearly. Business partners can easily adopt advanced analytics and derive new insights. These new insights promote innovation across disparate workstreams and solidify the decentralized approach to analytics taken by T-Mobile.
