1. Build and manage Serverless API Nicolas Grenié Hacker in Residence at 3scale @picsoung BarcelonaJS 22nd June 2016
2. @picsoung
3. 3scale.net/jobs
4. 700+ clients worldwide billions of API calls per month
7. There is hope hype

9. common questions you usually ask yourself
10. on prem vs cloud
11. how much storage
12. how much database
13. how much server power
16. Welcome to serverless era
17. no servers no deployments on servers no software to install
18. build once scale later
19. event driven functions
20. FaaS
21. Fonctions as a Service
22. action reaction
23. serverless is 2016 PaaS
24. actors Google
 CLOUD FUNCTIONS ALPHA
25. frameworks
27. pay per use logs with CloudWatch node, python, Java auto-scale AWS Lambda
28. Demo
29. community project AWS Lambda node and python handle roles minify code
30. $ sls project create
31. project structure s-project.json // project and author data s-resources-cf.json // CloudFormation template for all stages/regions admin.env // AWS Profiles - gitignored _meta // meta data that holds stage/regions config and // variables - gitignored |__resources // final CF templates for each stage/region |__s-resources-cf-dev-useast1.json |__variables // variables specific to stages and regions |__s-variables-common.json |__s-variables-dev.json |__s-variables-dev-useast1.json
32. $sls function create
33. project structure s-project.json // project and author data s-resources-cf.json // CloudFormation template for all stages/regions admin.env // AWS Profiles - gitignored _meta // meta data that holds stage/regions config and // variables - gitignored |__resources // final CF templates for each stage/region |__s-resources-cf-dev-useast1.json |__variables // variables specific to stages and regions |__s-variables-common.json |__s-variables-dev.json |__s-variables-dev-useast1.json restAPI // folder to group your project functions |__greetings // your first function |__event.json // sample event for testing function locally |__handler.js // your function handler file |__s-function.json // data for your lambda function, endpoints and event sources
34. $ sls function run
35. $ sls dash deploy
36. Use it for {API} ! AWS ecosystem
37. Manage the API
38. Manage the API simple API key no self-service no throttling by key no segmentation
39. 3scale API management
40. 3scale API management reduce latency not in the code deploy with cloudformation throttling by key support more auth protocol
41. Takeaways serverless = agility cost effective lot of platforms/tools serverless API need to be managed
