What is UBS's technology stack?
UBS runs on Microsoft Azure as its primary cloud platform. In October 2022 it said it planned to have more than 50% of its applications, including critical workloads, on Azure over five years, after reaching an earlier goal of one-third of applications in public cloud in February 2021. Engineers work on DevCloud, a DevOps platform built with GitLab since 2020. The AI layer sits on the same cloud: the Red assistants were developed with Azure AI Search and Azure OpenAI Service over approximately 60,000 digitized documents, and RiskLab, the data-science platform for over 1,200 data scientists, runs on Azure and was built on Domino Data Lab's product. The 2025 Form 20-F says Red and Microsoft 365 Copilot are deployed across the firm. The other half of the story is removal: by 30 September 2026 nearly all Credit Suisse IT applications in scope were no longer in use and around 90% were fully decommissioned, and over 18,000 software developers were using AI tools. UBS has not published a current share of applications in the cloud.[1][2][3][4][5][6][7]

What does UBS not disclose about its technology stack?
UBS has not published a current share of applications running in the cloud since the October 2022 plan of more than 50% on Azure over five years, and its results releases describe the Credit Suisse wind-down rather than the size of the remaining UBS estate.[1][7]
On AI suppliers, UBS's innovation page names Microsoft Azure and says the firm works with leading technology companies and select startups to keep 'choice, resilience, and access to the best available AI models and tools'; it does not list the model providers. The 2025 Form 20-F gives no technology budget or engineering headcount.[13][6]
