1. Functions Functions Faster to Deploy Faster to Deploy

3. wtfjs.com Adobe PhoneGap Apache Cordova
4. Functions Functions Time to get stoked.
5. Functions are the to a pure cloud native serverless architecture
6. Functions are the unit of deployment not the not the entire app entire app
7. Running containers negates the bene ts of "cloud "cloud native" native" functions like AWS Lambda or Azure Functions.
8. ♀ Almost as bad is putting your entire app in a single function. Downsides of a monolithic app plus ever increasing coldstart penalty.
9. Functions as a Service has nice characteristics
10. Only paying for what you use Only paying for what you use (% utilization)
11. Focusing on business value Focusing on business value instead of managing infra
12. Better lead times to production!
13. Better security model Better security model No ports to scan!
14. FaaS is best in class of FaaS is best in class of serverless! serverless! Fixed costs Faster iterations Better security
15. Major Major functions functions are faster to are faster to deploy! deploy!
16. arc.codes arc.codes
17. What What is is cloud functions based and Lambda is rst class vanilla node (run apps as a plain http server) monorepo of independant functions open governance AND open source arc.codes arc.codes
18. What What is NOT is NOT docker, k8s, vms or ANY server metaphors multicloud (but it is vendor neutral) legacy systems "lift and shift" arc.codes arc.codes
19. So why is a bunch of little functions a BFD?
20. Deploying a single function usually completes within a couple of seconds.
21. Deploy one or deploy all in parallel.
22. This is an order of magnitude improvement in most development work ow lead times to staging and/or production environments.
23. Speed. Speed. Authortime is faster Runtime smaller due to less deps Bug resolution easier
24. Faster...reading, writing, Faster...reading, writing, running and xing code! ♂ running and xing code! ♂ Seems worth exploring.
25. How tho?
26. DEMO TIME DEMO TIME NAO NAO
27. ⚠ Caution ⚠ Caution This story is still early Incremental adoption and participation
28. Solve with patience. Solve with patience. Multicloud functions will happen. But they have not happened yet.
29. Choose fast Choose fast by default. by default. Less code is faster on all dimensions: reading, writing, and running.
30. Let's be excellent to each Let's be excellent to each other. other. No more code shaming! There is no singular "right" way.
31. Get Involved Get Involved Pull requests are always nice Bug reports are APPRECIATED Feature requests are APPRECIATED Share what you learn on Twitter or blogs
