From Time and Location to Hardware Longevity: Core Principles of Sustainable Software Engineering
Getting on the same page about the essence and role of green IT, now let’s get a bit more specific and discuss how exactly your team can achieve sustainability in the development process. Here are the core principles to keep in mind:
Energy Efficiency
However, you can still manage resources wisely by keeping only the necessary servers active and avoiding idle ones. During off-peak hours, unused servers may be turned off or scaled down to save energy. Alternatively, you can leverage power scheduling to automatically reduce activity or shut down systems when demand is low. These steps will significantly contribute to efficient energy management without compromising the performance of your platform.
Carbon Awareness
Alternatively, you can run your entire operation in a more environmentally friendly location, where electricity is generated from cleaner energy sources. Take solar, wind, hydro, and geothermal, for example. They significantly reduce carbon emissions. Moreover, these sources can supply the necessary power for energy-intensive IT workloads.
Today, companies like Amazon, Google, and Microsoft have signed Power Purchase Agreements (PPAs) committing to buy electricity from solar or wind farms. It’s a pretty promising step towards improving sustainability in software engineering.
