18. Classification : Interne Observability and Continuous Improvement As key mindset 5
19. Classification : Interne Observability ➔ 19
20. Classification : Interne Take Away 6
21. Classification : Interne Take Away: main messages - Every Step Toward efficiency count - Measurement, And continuous improvement is the key for success - Adopting Green API/Sofware Principles/Patterns and Practices is our ally - Leveraging Opensource 21
22. Classification : Interne Take Away: tools/resources sharing 22 1- AxaFrance/dailyclean: Save The planet by auto turn off your pods on kubernetes (github.com) 2- AxaFrance/SlimFaas: SlimFaas : The slimest and simplest Function As A Service (github.com) 3- Green-Software-Foundation/if: Impact Framework (github.com) 4- cnumr/ecoCode: Reduce the environmental footprint of applications with this sonarQube plugin 5- LightHouse-ecoIndex-Agregator Axa France (github.com) 6- Sustainable-computing-io/kepler: Kepler (Kubernetes-based Efficient Power Level Exporter)
23. Classification : Interne Call To Action 7
24. Classification : Interne Call To Action: We Need You - Be The Change ▪ Adopt Green By Design ▪ Adopt Green Coding practices - Start Small, Scale Big ▪ Join global conversation ▪ Learn from - Sustainable Code = Sustainable Future ▪ Commit to measuring and reducing 24
