1. Win-Win solutions on the path to Sustainability by Artem Yakimenko
2. The Carbon Footprint of Digital Services
3. Understanding Where Tech Emissions Come From Scope 1 Direct emissions from owned sources (5-10%) Scope 2 Indirect emissions from purchased energy (10-15%) Scope 3 Value chain emissions, e.g. Cloud hosting (75-85%) *Data from foundational reports from Global e-Sustainability Initiative (GeSI) and the Responsible Business Alliance (formerly EICC).
4. Why Culture Amp? - Our research has shown that sustainability commitments drive employee engagement. - Our leadership and many of our investors care deeply about sustainability. - We’re a B Corp with an ambitious Net Zero plan.
5. Why infrastructure? Data centre providers rank among our top three suppliers by emissions.
6. Personal interest • Environmental scientist by education ◦ GIS/Geo-Ecology major
7. Project Goals & Approach Cost Savings Sustainability Performance
8. Efficient Hardware Newer Generation CPUs - Replacing older architectures (e.g. Broadwell) with newer X86 generations - How many of those M4’s / T4s do you still have running?
10. Efficient Hardware ARM Architecture - Smaller number of instructions, less legacy compatibility to maintain, less circuitry to decode and execute. - Simple instructions take predictable amount of time, allowing for easy optimization/”pipelining”. - All that leads to high performance-per-watt.
11. Efficient Hardware ARM Transition - Transitioning to ARM (via Graviton) improved both costs (10%+) and emissions (50%+) - Very easy to do for vendor-hosted services (e.g. AWS RDS) - Apps require work but trivial if you run newer runtimes (e.g. Ruby > 3.0, Golang > 1.18, JDK17+)
12. Fix Resource Utilization Right-sizing things based on actual usage Review idle resources - Use cloud provider tooling Leverage instance marketplaces (AWS Spot) Deploy "Just In Time" Computing - Product metrics vs monitoring data - does your compute follow the active users? - Infrastructure inventory
13. Fix Resource Utilization Right-sizing things based on actual usage Leverage oversupply - AWS/Azure Spot, GCP Preemptible Leverage instance marketplaces (AWS Spot) Deploy "Just In Time" Computing - Stabilize by using capacity calculators (e.g. AWS Spot Instance Advisor)
14. Fix Resource Utilization Right-sizing things based on actual usage Economies of Scale Take advantage of just-in-time compute Leverage instance marketplaces (AWS Spot) Deploy "Just In Time" Computing optimized for you already, e.g.: - AWS ECS Fargate - GCP Cloud Run
15. Fix Resource Utilization Right-sizing things based on actual usage Be pragmatic - Easy to reach diminishing returns Leverage instance marketplaces (AWS Spot) Deploy "Just In Time" Computing - Rank opportunities by cost - Keep score - Helps gamify the efforts & learn lessons - Leverage vendor partnerships
16. Align your architecture Right-sizing things based on actual usage Measure performance - Are your CPU cores running or idling? Leverage instance marketplaces (AWS Spot) Deploy "Just In Time" Computing - Are you optimising for average or median memory use? - What are your bottlenecks? - Humans like even numbers. Does your app need 100GB or 90GB?
17. Align your architecture Right-sizing things based on actual usage Optimise performance - Async processing can save tons of money Leverage instance marketplaces (AWS Spot) Deploy "Just In Time" Computing during less busy hours using spare compute. - Scale down depending on region / customer shards. - Question your standards. You’d be surprised with how little you might need.
18. Results 49% 12% Carbon emissions reduction Cost reduction
19. What can I do? - Best time? Yesterday. - Second best? Now! - Take advantage of: - performance - security - efficiency improvements
20. What can I do? Do it where it makes sense: - usually better emissions - simpler operations - less overhead - better scalability
21. What can I do? Costs correlate to CO2 impact: - minimize waste - do regular reviews - keep score to motivate yourself and others
22. Sustainability: Good for the world Good for you Good for your customers
