The telecommunications industry has reached a critical inflection point where legacy IT systems can no longer support the demands of an AI-first world. Traditional telco technology approaches are too complex, slow, and fundamentally incompatible with the speed and agility required for modern digital services. Today I'm speaking with Dr. Lester Thomas, head of new technologies and innovation at Vodafone Digital and IT, and a TM Forum Distinguished Fellow. Lester has driven some of the most ambitious cloud transformation projects in telecom, including Vodafone's groundbreaking data migration that consolidated servers across multiple countries into a unified cloud platform. We explore Vodafone's "Composable IT" vision and how the company is transforming its technology stack to be modular, open, and AI-ready.
Watch now to hear:
-Vodafone's data transformation that moved 17 petabytes from 600 Hadoop servers hosted in 11 countries into Google Cloud, creating the foundation for AI adoption [02:17]
-The company's strict "cloud native" definition requiring complete re-engineering rather than lift-and-shift, with 80-90% of digital workloads now truly cloud native [08:33]
-Three principles driving Vodafone's Open Digital Architecture: machine-readable standards, open-source collaboration, and proof-of-concept testing over RFPs [13:13]
-How AI is forcing complete software redesign, with Vodafone's AI Booster democratizing AI access across all business functions while maintaining governance [17:59]
