- 12. clda.co/lambda-‐edge-‐milano Benefits and use cases Analisi dei casi d’uso più interessanA
- 13. AWS Lambda@Edge Use cases clda.co/lambda-‐edge-‐milano Request/Response manipulaKon Dynamic content generaKon Pure latency opKmizaKon
- 14. 1. Request/Response manipulaQon clda.co/lambda-‐edge-‐milano Custom HTTP headers Adapt to client capabiliKes Add Kmezone-‐related info A/B tesKng URL rewriKng / redirects EncrypKon at the Edge
- 15. 2. Dynamic content generaQon * clda.co/lambda-‐edge-‐milano Custom error pages Custom signup forms Opzimized JS code (Polyfill.io) Dynamic HTML * Never hit the origin!
- 16. 3. Pure latency opQmizaQon * clda.co/lambda-‐edge-‐milano 401 errors if missing auth Edge-‐based logging Custom data validaKon Custom data transformaKon * Assuming dynamic origin
- 17. clda.co/lambda-‐edge-‐milano Preview & GA Quali restrizioni incontriamo durante l’anteprima limitata, e cosa cambierà?
- 18. LimitaQons (preview only) clda.co/lambda-‐edge-‐milano Max 50ms Only 128MB (RAM) Only 1MB of code Only Node.js 4.3 Programming model Only 1 trigger
- 19. LimitaQons (permanent) clda.co/lambda-‐edge-‐milano Cold starts Only Node.js No VPC No API Gateway distribuKons Slow propagaKon (~5min) No real-‐Kme logging No DLQ Explicit HTTP convenKons
- 20. General Availability (soon!) clda.co/lambda-‐edge-‐milano HTTP calls / AWS SDK Dynamic Content! Beier (3rd-‐party) monitoring More RAM, Kme, and storage MulKple triggers Beier LocaKon awareness
- 21. clda.co/lambda-‐edge-‐milano Lambda@Edge Pricing $0.60 / 1M calls (requests) $1.00 / 3M calls (duraKon) No Free Tier 50ms granularity Example: 6M calls ~ $5.6
- 22. clda.co/lambda-‐edge-‐milano My personal experiment Finalmente un po’ di codice :)
