JavaScript Saves The World - DotJS 2019

Data Centres produce about 3% of the worlds greenhouse gases and this is set to treble in the next 10 years. When building apps, we focus on minimising costs, time to market, bugs, bundle size, application speed, SEO, but we spend almost no effort trying to minimise the damage our applications are making to the environment. In this talk, we'll discuss how to build a green sustainable web application with NestJS and Serverless.

4. What is Green? @jawache
5. CO2e @jawache
6. 2°C https://en.wikipedia.org/wiki/Paris_Agreement @jawache
8. WE are not on track @jawache
9. As developers you can have an outsized impact @jawache
10. Electricity is responsible for 30% of CO2e @jawache
11. On average 80% of the worlds electricity is created from the burning of Fossil Fuels @jawache
12. Don't waste electricity @jawache
13. Use Clean Electricty @jawache
14. Microsoft Azure Google Cloud AWS (only Dublin, Frankfurt, Oregon or Canada) carbon neutral clouds @jawache
15. how wasteful are servers? @jawache
16. @jawache server "carbon" cost
17. @jawache ~600 kg CO2e to run/year Idle servers consume ~25% of the electricity compared to peak load ~150 kg CO2e to run/year server "carbon" cost
18. @jawache (Assuming a 4 year lifespan) 320 kg CO2e to create/year server "carbon" cost
19. @jawache An idle server wastes about 470 kg CO2e per year server "carbon" cost
20. how can Serverless help? @jawache
21. https:!//azure.com/app1234/v1/moo/foo what is serverless? @jawache
22. • Autoscales • Pay as you go • Unit of measurement is not servers what is serverless? @jawache
23. @jawache what is serverless?
24. @jawache what is serverless?
25. • CO2e was released to create a server • CO2e was released to power a server • If you don't run at 100% utilisation you are wasting CO2e • Serverless let's us run servers at 100% serverless is greener because? @jawache
26. how to Serverless in Node.js? @jawache
27. Azure functions AWS Lambda Google cloud functions @jawache
29. Let's Talk Sure!
