U.K. Enterprises Embrace Sustainable Cloud-Native AWS

Organizations use cloud-native and AI innovations to modernize legacy systems, enhance efficiency, ISG Provider Lens^® report says

LONDON--(BUSINESS WIRE)-- Enterprises in the U.K. are accelerating cloud migration and data transformation centered on AWS, with strong momentum across industries, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.

The 2025 ISG Provider Lens^® AWS Ecosystem Partners report for the U.K. finds that enterprises are using AWS’ advanced AI and cloud services to modernize operations and improve overall efficiency. Especially in manufacturing, healthcare and financial services, organizations are seeking solutions from AWS service providers to address functional challenges and enhance decision-making.

“U.K. enterprises are moving from selective adoption to integrated use of AWS technologies across their operations,” said Anthony Drake, ISG partner, U.K. market. “As AWS expands its capabilities in the region, organizations in the U.K. are embracing a new phase of cloud maturity, balancing innovation with a sharper focus on resilience.”

U.K. enterprises are updating their cloud environments in response to increasing geopolitical and regulatory complexity, the report says. The issue of cloud sovereignty is moving beyond data residency requirements to include cloud software and operations. Most AWS ecosystem providers now offer sovereign cloud solutions, aimed especially at clients in highly regulated sectors such as defense, healthcare and government.

Serverless computing continues to gain traction among U.K. enterprises, ISG says. Companies are using AWS Lambda, App Runner and Step Functions to build distributed, event-driven applications without the need to manage underlying infrastructure components. This approach simplifies deployment and enables faster, more reliable application delivery across varied workloads. Organizations are also adopting AWS tools to improve customer experience, using Amazon Connect and Amazon Q to enhance contact center operations and analyze behavioral data for more personalized and efficient customer interactions.

Enterprises are focused on end-to-end cost optimization within their AWS environments, the report says. Rather than relying solely on FinOps practices, organizations are incorporating cost efficiency throughout cloud migration and modernization. This includes early rightsizing of cloud resources, modernization during migration and adoption of AWS Graviton-based instances and AWS Nitro virtualization for enhanced performance and resource optimization. This full-lifecycle approach helps enterprises minimize technical debt, improve utilization and manage operational costs more effectively across their AWS workloads.

“U.K. enterprises are accelerating modernization by implementing AI, cloud-native and serverless technologies,” said Mark Purdy, lead author of the report. “AWS providers are playing a central role in helping organizations streamline operations and achieve measurable efficiency gains.”

The report also explores other AWS ecosystem-related trends in the U.K., including the continued use of AWS tools to support sustainability goals and the growing integration of analytics platforms to enhance data-driven decision-making across U.K. enterprises.
