Adaptive Green Cloud Applications: Balancing Emissions, Revenue, and User Experience through Approximate Computing

We present a carbon-aware application management approach that leverages approximate computing techniques to balance sustainability, user experience, and revenue. Our method dynamically optimises the configuration and scaling of individual software components within a predefined carbon budget. Through simulation-based evaluation across diverse regions, carbon budgets, and application setups, we demonstrate that the approach effectively adapts to fluctuating workloads and regional variations in carbon intensity.
