Mind the gap: Exploring software architecture in the UK

After participating in vFunction's application modernization workshops in the U.K., the author observed notable differences between U.K. and U.S. engineering teams' approaches to software architecture, as detailed in the 2025 Architecture in Software Development Report. While both regions experience AI-driven changes in software development, U.K. organizations face greater operational challenges, with 95% reporting issues related to architectural instability, leading to service disruptions and increased costs. However, U.K. teams exhibit higher adoption rates of OpenTelemetry, improving their ability to monitor and manage software systems effectively. Larger U.K. enterprises also demonstrate better architecture integration throughout the software development lifecycle compared to smaller firms, suggesting a proactive approach to managing complexity. The full report provides further insights into industry leaders, risks, and the impact of AI on software architecture.
