UOB and Amazon Web Services have signed a memorandum of understanding to develop a hybrid infrastructure model for banking in ASEAN, centred on a dedicated cloud environment in Singapore.

The agreement will explore how cloud and artificial intelligence can support UOB's operations across Singapore, Malaysia, Thailand, Indonesia and Vietnam. The focus will be on hybrid cloud architecture, data and analytics, and AI-led customer engagement.

The arrangement is intended to create a model in which the bank's systems and data can operate across on-premises infrastructure and cloud environments. It includes an isolated cloud extension that could be deployed in specific countries or jurisdictions where local regulatory requirements apply.

The dedicated environment in Singapore is intended to meet UOB's security, governance and data residency requirements across its five ASEAN markets. The bank said its data and systems would remain within that environment while being configured to support compliance with rules in each market.

AWS and UOB described the project as their first collaboration to combine hybrid cloud arrangements in ASEAN with security, governance and data residency controls designed for a heavily regulated industry.

Beyond infrastructure, the companies will examine how AI tools could be applied to customer experience and internal operations. Areas under review include conversational banking services and more personalised offerings for customers.

UOB said the work would build on its existing Enterprise GenAI Platform. It will also explore the use of Amazon Bedrock to develop and deploy AI-based services across the bank, from employee productivity tools to broader internal applications.
