The Things Network - End to End Serverless Applications

In this talk, I presented a workable architecture for designing your Lorawan application in a serverless matter.

This architecture does not involve any servers, and uses AWS Lambda functions to get things done. It is connected to The Things Network using the HTTP integration

4. WHAT IS SERVERLESS?
5. PERSPECTIVE. •VM's •Hardware abstraction •Unit of scale: machines WHAT IS SERVERLESS?
6. PERSPECTIVE. •VM's •Hardware abstraction •Unit of scale: machines •Containers •OS abstraction •Unit of scale: application WHAT IS SERVERLESS?
7. PERSPECTIVE. •VM's •Hardware abstraction •Unit of scale: machines •Containers •OS abstraction •Unit of scale: application •Serverless •Runtime abstraction •Unit of scale: functions WHAT IS SERVERLESS?
8. PERSPECTIVE. •VM's "I want to configure machines, storage, networking and my OS" •Containers "I want to run servers, configure applications and control scaling" •Serverless "Run my code when it's needed" WHAT IS SERVERLESS?
9. PERSPECTIVE. By Simon Wardley: https://twitter.com/swardley/status/951783539334352896 WHAT IS SERVERLESS?
10. WHAT IS SERVERLESS? "An application running on 3rd party services (BAAS) and/or using serverless computing (FAAS)" - Martin Fowler WHAT IS SERVERLESS?
11. WHAT IS SERVERLESS? "An application running on 3rd party services (BAAS) and/or using serverless computing (FAAS)" - Martin Fowler WHAT IS SERVERLESS?
12. BAAS/FAAS. WHAT IS SERVERLESS? •BAAS: Backend As A Service - Databases: Parse/Firebase/etc - Authentication: Auth0, AWS Cognito - etc... •FAAS: Functions As A Service
13. PROVIDERS. Google Cloud Functions Azure Functions AWS Lambda WHAT IS SERVERLESS?
14. WHY SERVERLESS?
15. PATCHING?! Patching? YAY!
 Said no one ever. WHY SERVERLESS?
16. PATCHING?! WHY SERVERLESS?

18. RUNTIMES. •C# .net core 1.0/2.0 •Go 1.x •Java 8 •NodeJS 4.3, 6.10 •Python 2.7, 3.6 WHY SERVERLESS?
19. EVENT BASED. • API Gateway • AWS IoT • Alexa Skills Kit • Alexa Smart Home • CloudWatch Events • CloudWatch Logs • CodeCommit • Cognito Sync Trigger • DynamoDB • Kinesis • S3 • SNS WHY SERVERLESS?
20. STATELESS. Event doStuff(event) Time ! WHY SERVERLESS?
21. STATELESS. doStuff() Time doStuff() doStuff() doStuff() doStuff() doStuff() doStuff() doStuff() ! ! ! ! ! ! ! ! WHY SERVERLESS?
22. SCALABLE BY DEFAULT. Seconds WHY SERVERLESS? Provisioned Servers Requests / second 0 100 200 300 400 0 10 20 30 40 50 60 70 80 90 100 110 120 130 Requests

24. COSTS. Pay per usage VM's: per minute WHY SERVERLESS?
25. COSTS. Pay per usage VM's: per minute Lambda: Per 100ms + per request WHY SERVERLESS?
26. COSTS. Pay per usage VM's: per minute Lambda: Per 100ms + per request $0.000000208 / 100ms + $0.0000002 / request
27. FREE STUFF! WHY SERVERLESS?
28. FREE STUFF! 400.000 GB-seconds / month 1 Million requests / month WHY SERVERLESS?
29. COSTS. Example: 10.000 devices Updates every hour @ random 2 seconds to process WHY SERVERLESS?
30. COSTS. Traditional: ~$250/m WHY SERVERLESS?
31. COSTS. Serverless: WHY SERVERLESS?
32. COSTS. Serverless: ~7.440.000 executions ~2000 msecs WHY SERVERLESS?
33. COSTS. Serverless: ~7.440.000 executions ~2000 msecs WHY SERVERLESS?
