6. 3 Clouds
7. 100+ Products
8. Many acquisitions
9. Diverse Technology Stack
11. Big Cloud Users
12. Behind some of the biggest brands
13. Question: how to make it all play together?
14. Question: how to make it play with the rest of the world?
15. Answer: let’s build a cool website
17. Just kidding
18. Who is building integrations? Who is building apps with Adobe APIs? Who is building experiences using Adobe Products?
19. Developers, Developers, Developers
20. What Developers Want
21. → Write Code → Deploy Code → Manage Servers
22. → Write Code → Deploy Code → Manage Servers → Drink Beer
23. → Write Code → Deploy Code → Manage Servers → Drink Beer
24. Servers: can’t live with them, can’t live without them.
25. Here is our 4-Step plan to serverlessness
26. 1. Put Servers behind Glass
28. APIs
29. API Gateway
30. → Caching → Throttling → Authentication → Logging
31. From dumb proxy to smart gateway
32. → Hide yo monoliths → Establish API practices → Provide easy access
33. → NGINX → OpenResty → Lua
34. !" https://github.com/adobe-apiplatform/apigateway
35. Establish API Best practices
36. Establish API Best practices
38. 2. Contain your Applications
40. Containers
41. Ethos → Standardized Container OS → Standardized CI/CD pipeline → Feature flags as a Service
42. 3. Put Code on the Short Leash
44. Serverless Runtime
45. Never trust a computer you can't throw out a window. — Steve Wozniak
46. Never trust code you can’t terminate after one second. — Dragos Dascalita Haut
47. Serverless Integrations → WebHooks++ → Low Latency → Low Maintenance
48. Our needs → Untrusted Code → Extensibility + Context → Cloud Provider Independence
50. Are you guys serious about the delivery date? — John Pritchard, Director Engineering
51. OpenWhisk !" https://github.com/openwhisk/openwhisk
53. http://bit.ly/apachewhisk
54. 4. Wait for the call
56. Event Gateway
57. Why Events? → Asynchronous Processing → Function Orchestration → Reliability & Scalability
58. Demo Because everyone ♥ bots
59. ┌───────────────────┐ ┌───────────────────┐ ┌───────────────────┐ │ │ │ │ │ │ │ │ │ │ │ │ │ Alexa ! │──────────▶│ API Gateway " │──────────▶│ OpenWhisk # │ │ │ │ │ │ │ │ │ │ │ │ │ └───────────────────┘ └───────────────────┘ └───────────────────┘
61. Training Alexa ┌─────────────────┐ ┌─────────────────┐ │ │ │ │ │ │ │ │ │ Intent │⾢─────────▶│ User Phrase │ │ │ │ │ │ │ │ │ └─────────────────┘ └─────────────────┘
62. Training Alexa How many page views this month? { "intents": [ { "intent": "PageViews" } ] }
63. Training Alexa How many {metric name} this month? { "intents": [ { "intent": “CustomView”, "slots": [ { "name":"MetricName", "type":"LIST_OF_METRICS" } ] } ] }
64. Writing the Function Copy the code !" http://bit.ly/dragosdemo Add the function on the CLI wsk -i action create alexa alexa-demo.js
66. Why the gateway? Alexa Headers: SignatureCertChainUrl, Signature & … OpenWhisk expects: Authorization
67. Signature !1 Authorization 1 not real magic
