Ep 81 – Best of 2023: The cloud-first mindset, with Mobi CEO Justen Burdette
Our top episode from 2023: my interview with Mobi CEO Justen Burdette about the Hawaiian MVNO's work to implement its own public-cloud-native, mobile core.
BT Group started its journey to the public cloud years ago, which has put the company in a strong position to take advantage of the strategic capabilities of artificial intelligence (AI). For this episode, I talk with Josie Smith, chief architect, digital, at BT Group, about the company’s efforts to reduce its applications from thousands to hundreds, bring AI into the organization, and drive monumental change across its employee base. Listen now to hear:

BT Groupās Simplify program is targeting Ā£3 billion in savings by the end of 2025 through a comprehensive digital transformation. The program focuses on three key areas: modernize (simplifying the application estate from 2,400 to 500 apps and moving 90% to public cloud), engage (digitally connecting with customers more personally), and grow (expanding into adjacent sectors beyond traditional broadband and mobile). By reducing technical debt, eliminating duplication, and focusing on cloud-native solutions with partners like AWS and Google Cloud, BT is doubling productivity while improving customer service capabilities.
BT Group identified massive duplication and inefficiency across its application landscape that hindered agility and customer service. The reduction strategy involves multiple approaches: eliminating applications no longer serving the business, consolidating duplicated systems (applying a ārule of oneā principle), and refactoring applications to be cloud-native. By moving to modern, simplified architecture, BT frees developers from infrastructure management tasks like patching and certificate management, allowing them to focus on delivering customer-focused features quickly. This transformation positions BT to leverage AI capabilities more effectively.
BT Group is pursuing a multi-cloud strategy with 90% of applications targeted for public cloud deployment. The company uses AWS for applications, Google Cloud Platform (GCP) for data, and Azure for internal capabilities. Chief Architect Josie Smith oversees cloud landing zones for all three vendors and leads the āshift to cloudā program. The approach emphasizes proper foundations firstāincluding data fabric implementation with Ab Initio for metadata managementābefore accelerating AI adoption. This five-year transformation journey focuses on refactoring applications to leverage cloud-native services rather than simple lift-and-shift migrations.
Danielle Royston advocates for rewriting legacy applications using cloud-native components rather than lifting and shifting old code. She shares an example where a company reduced an application from over a million lines of code to just 3,500 lines on Google Cloud and 6,000 on AWSāless than 1% of the original code base. This approach leverages specific cloud provider software components, reduces bug risk and Sev 1 outages, and saves time, money, and headcount. DR offers to help telcos refactor applications and choose the right cloud platform ecosystems.
Josie Smith emphasizes that AI tools are only as good as the data feeding them, making proper data foundations critical. BT implemented a data fabric using Ab Initio to ensure smart data movement and metadata tracking across systems. The company focuses on understanding data sources, maintaining good metadata, and avoiding ādata sludge.ā Beyond technical foundations, BT invests in people through reskilling initiativesāproviding access to tools like CodeWhisperer and Copilot, creating a digital campus learning platform, and embedding data experts in business units. BT has deployed 15 algorithms generating value in the last year.
