The Green Shift: Transitioning .NET Services Across Architectures

Anne Currie is joined by Sara Bergman to explore what the shift to greener computing really looks like in practice, using .NET and modern CPU architectures as a concrete example. They unpack why moving from traditional x64 systems to more efficient ARM-based platforms can cut costs and carbon, how runtime environments like .NET make architectural transitions easier, and why staying up to date with platforms is essential for performance, security, and sustainability. Along the way, the conversation connects DevOps, modernization, and energy efficiency into a clear message: the green shift starts with building systems that are designed to change.

Root and Branch and SCI-Web

Host Chris Adams talks with Adam Newman and Oli Winks of Root & Branch about their new Software Carbon Intensity Web model for measuring the real carbon footprint of websites. They break down why current methods miss the mark, how their bottom-up approach captures actual energy use across servers, networks and devices, and why better measurement can lead to smarter, lower-carbon choices for teams. It’s a candid look at what it really takes to make the web greener, and the tools that can help developers get there.

Software Architecture for Sustainability

Guest host Anne Currie speaks with Karthik Vaidhyanathan, Assistant Professor at IIIT Hyderabad, about integrating sustainability into AI development. They discuss how the world can balance digital growth with renewable energy goals and how AI systems can be designed to be energy-efficient rather than energy-intensive. Karthik shares insights from his research on sustainable AI and MLOps, including dynamically selecting and retraining models to cut energy use and costs without compromising performance. The conversation underscores the importance of dynamic system design and collaboration across academia, industry, and government to make sustainability a core principle in software engineering.
