🧩 Green Software / Sustainable Architecture

✅ Overview​

Software design approach conscious of energy efficiency, carbon reduction, and resource optimization.

✅ Problems Addressed​

  • Increase in energy consumption due to system expansion.
  • "Invisibility" of CO2 emission accompanying cloud usage.
  • Wasteful resource usage (Idle operation / Over-scale).

✅ Basic Philosophy & Rules​

  • Visualization of carbon efficiency (Carbon Intensity / GreenOps).
  • Optimization of scheduling (Low carbon time zone).
  • Utilization of Serverless / Auto-scale.
  • Data reduction (Reduction of unnecessary data storage).
  • Selection of energy-efficient algorithms.

✅ Suitable Applications​

  • Large-scale data processing infrastructure.
  • Mobile / IoT requiring power saving.
  • Enterprises requiring cloud optimization.

❌ Unsuitable Cases​

  • Environment where environmental data cannot be acquired.
  • Small-scale systems where effect of energy efficiency is small.

✅ History​

  • Launch of Green Software Foundation.
  • Cloud Sustainability became industry theme.

✅ Related Styles​

✅ Summary​

Green Software is a concept for Sustainable Software Design,
and is an architecture considering energy efficiency and CO2 reduction from design stage.
