Presentation gave by Nicolas Grenié (@picsoung) at APIdays Nordic in Tampere, Finland in 2016 He covered the principles of serverless infrastructure, explaining the pros and cons about it and the different platforms. He also gave an overview of the Serverless (serverless.com) framework.

2. @picsoung

3. 3scale.net/jobs

4. 700+ clients
worldwide
billions of API calls per month

7. There is hope
hype

8. http://www.commitstrip.com/en/2013/03/11/de-lestimation-de-la-charge/by CommitStrip

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

15. Welcome to
serverless
era

16. no servers
no deployments on servers
no software to install

17. build once
scale later

18. event driven
functions

19. action
reaction

20. serverless
is
2016 PaaS

21. actors
Google
CLOUD FUNCTIONS ALPHA

22. frameworks

23. 101

24. pay per use
logs with CloudWatch
node, python, Java
auto-scale
AWS Lambda

25. community project
AWS Lambda
node and python
handle roles
minify code

26. $ sls project create

27. 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

28. $sls function create

29. 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

30. $ sls function run

31. $ sls dash deploy

32. Manage the API

33. Manage the API
simple API key
no self-service
no throttling by key
no segmentation

34. 3scale API management

35. 3scale API management
reduce latency
not in the code
deploy with cloudformation
throttling by key
support more auth protocol

36. Try it
http://bit.ly/API-workshop

37. Takeaways
serverless = agility
cost effective
lot of platforms/tools
serverless API need to be managed

38. Build and manage
Serverless API
