1. Aavista Oy Merja Kajava APIDays Helsinki & North 2024 Sustainable IT and API Performance - How to Bring Them Together
2. Washington Post March 7, 2024 Goldman Sachs May 14, 2024
3. Demand for electricity in North America has doubled 9-year growth forecast of demand for new electricity, in gigawatt hours
4. Source: IEA (2024), Electricity 2024, IEA, Paris https://www.iea.org/reports/electricity-2024 “Electricity consumption from data centres, AI and the cryptocurrency sector could double by 2026” Data centres +29 TWh Increase Estimated drivers of change in electricity demand in the EU, 2021-2026
5. 0,3 2,9 Google search ChatGPT request Energy consumption (Wh) ~10x Source: Alex de Vries (2023).The growing energy footprint of artificial intelligence. Joule, Volume 7, Issue 10, 2023 https://doi.org/10.1016/j.joule.2023.09.004 Substantial differences in energy consumption for search APIs
6. Source: Aavista City Countries with largest response times Differences in performance by API providers for the same API
7. The elements of API performance Scalability Performance Response times Request and/or response sizes Backend “efficiency” Network latency Throughput
8. API performance is shared between the API provider and the API consumer API Provider API Consumer Payload size Frequency
9. API Performance – The API Consumer API Provider API Consumer How many API requests ? What is the request size ? What is the response size ? Is paging used ? Is caching applied ?
10. API Performance – The Network API Provider API Consumer What is the network capacity ? What is the latency ? End-user
11. API Performance – The API Provider API Provider API Consumer 3rd Party API How many API requests to private APIs ? How many API requests to 3rd party APIs ? Is caching applied ?
12. API Performance – The Scalability API Provider API Consumer How many API consumers ? How many concurrent requests ? What is the frequency of the requests ?
13. API backend efficiency is built from the design Architecture API design Technology choices Calls to other APIs
14. SPECIFY PERFORMANCE REQUIREMENTS TEST PERFORMANCE MONITOR PERFORMANCE ADJUST Monitoring the API performance is an on-going activity
15. What about the carbon footprint for APIs
16. Carbon footprint calculators as part of the cloud billing Google Cloud - Carbon Footprint AWS - Customer Carbon Footprint Tool Note the scopes Scope 1 Scope 2 Scope 3
17. Carbon footprint calculators for multi-cloud environments Cloud Carbon Footprint https://www.cloudcarbonfootprint.org Azure AWS Google Cloud
18. A sustainable API solution = A well-performing API + Responsible use of the API
19. The Data Refinery Company Merja Kajava https://www.linkedin.com/in/merjakajava
