Architectural Innovations in Green Computing Systems
Concepts and Core Goals of Green Computing
Green computing is a design methodology for computational systems centered on sustainability, aiming to achieve harmonious coexistence between computational systems and natural environments through optimized resource utilization and reduced environmental impact. Its core goals include: reducing energy consumption, lowering carbon emissions, enhancing resource reuse efficiency, and extending hardware lifespans.
In traditional computing architectures, the high energy consumption of data centers, servers, and network devices is particularly pronounced. Green computing introduces novel technological approaches to redefine energy consumption patterns of computational systems, enabling high-performance requirements while minimizing environmental burdens.
