Cloud Sustainability Model using C4 Context diagram illustrates how Users, Cloud Service Providers, Data Centers, and Renewable Energy Sources interconnect within a Sustainable Cloud Platform. The architecture flows energy from Renewable Energy Sources through Data Centers to power cloud services, while Monitoring and Analytics System tracks energy and carbon metrics in real time. Sustainability Policies and Optimization Engine continuously optimizes resource efficiency to minimize environmental impact and operational costs. This pattern demonstrates how to embed sustainability governance into cloud infrastructure design, addressing growing regulatory and corporate ESG requirements.
