2. 2 It’s gettin’ kinda hot in herre
3. “HONEY, I SHRUNK THE CARBON FOOTPRINT!” Boosting Sustainability in the Cloud PHILIPP SEIFERT-KEHRER 4 July 2024
4. 4 WHAT ABOUT ME? • Developer for 7+ years • @ Posedio since 2022 • Sagittarius with an Aquarius rising • Cat Lover • Oddly nostalgic about monoliths
5. ROADMAP 1. Sustainability Xs and Os 2. Efficiency 3. Awareness 4.Cloud 5. Reshaping our process
6. SUSTAINABILITY XS AND OS 1
7. 7 SUSTAINABILITY – WUT? “the quality of being able to continue over a period of time” OR “the quality of causing little or no damage to the environment and therefore able to continue for a long time”
8. 8 SUSTAINABILITY – WHY?
9. 9 DO WE REALLY HAVE TO?
10. 10 CARBON NEUTRAL VS NET ZERO • Carbon neutral = offset • Net zero = reduction
11. 11 SAVED BY OR DESPITE TECHNOLOGY? Software Decarbonization Decarbonized Software VS
12. 12 SO, WHAT TO EXPECT FROM THIS TALK? Look at practices and the mindset shift necessary to tackle climate change within our role as software engineers
14. 14 GREEN SOFTWARE = EFFICIENT SOFTWARE Less Energy for same result Applying well- known practices
15. 15 PRINCIPLES TO UP THE EFFICIENCY GAME Get the best out of your code Make the choice of tools matter Accountability!!!
16. 16 WHAT ABOUT MY DEVELOPER EXPERIENCE?
17. 17 TRAVEL LIGHTLY Data Transmission Energy consumption > Data Centers Energy consumption
18. 18 TRANSMISSION REDUCTION PRINCIPLES Servers close to end users Reduced payload size HTTP2 Mobile First
19. 19 MAKE MONOLITHS GREAT AGAIN?
20. AWARENESS 3
21. 21 QUESTION OF WHEN AND WHERE
22. 22 QUESTION OF CARBON INTENSITY
23. 23 WHERE?
24. 24 WHEN?
25. 25 HOW WILL I KNOW?
26. 26 HOW WILL I KNOW?
27. 27 DEMAND SHAPING
28. CLOUD 4
29. 29 PUBLIC CLOUD AS SUSTAINABILITY ENABLER High Utilization Spot / Preemptible instances Stateless patterns Out of the box security Storage lifecycle management BUT: also enabler for…
30. 30 OVERPROVISIONING
31. 31 USE THE CLOUD, BUT… Kill Zombie projects / resources Use automatic data retention Minimize availability of non-prod environments Be clear about SLAs & requirements Use the right (not the fancy) tool
32. RESHAPING OUR PROCESS 5
33. 33 YOU CANNOT CHANGE WHAT YOU CAN’T MEASURE
34. 34 ACROSS CLOUDS
36. 36 PART OF THE PROCESS
37. 37 A NEW NON-FUNCTIONAL REQUIREMENT Maintainability Availability Scalability Sustainability
38. 38 IS THAT ALL WORTH IT? … or are we only moving inches?
39. 39 THE PLANET WILL DIE IF YOU DON’T… Maintainability Availability Scalability Sustainability rewrite your whole code base in Rust refactor your microservice architecture to a monolith run batch jobs during the day put all your GCP resources to Finland screw Productivity and spend all day optimizing for Sustainability
40. 40 … but we kinda have to…
