Function as a service (FaaS) is a way to keep the focus on business delivery. Basically, we don't know how our code will run, infrastructure. Here we now how aws lambda works and how to run PHP into AWS Lambda

1. PHP
as a Service
Paulo Victor Gomes
@_pvgomes CTO at Mundo Verde and Natue

2. XaaS ? (IaaS/SaaS/PaaS/FaaS/CaaS)

3. Function as a Service - FaaS/Serverless
Software developers can leverage this to deploy an individual
“function”, action, or piece of business logic. They are expected to
start within milliseconds and process individual requests and then
the process ends.
Principles of FaaS
- Complete abstraction of servers away from the developer
- Billing based on consumption and executions, not server
instance sizes
- Services that are event-driven and instantaneously scalable

4. Serverless Infrastructure Providers

5. A simple AWS Lambda

6. A simple AWS Lambda

7. A simple AWS Lambda

8. A simple AWS Lambda - deploy
Package the code
Upload with aws cli

9. Make your life easier

10. Serverless + AWS Lambda

11. Serverless configuration

12. Serverless + AWS Lambda

13. Serverless + AWS Lambda

14. What about PHP?

15. PHP as a Service - FaaS
1 request = 1 process

16. PHP as a Service - FaaS
PHP is faas-ready

17. What about AWS Lambda and PHP?
AWS lambda does not support PHP

18. NodeJs PHP Handler

19. Is that ok for you?

20. AWS Lambda Layers

21. Install AWS SAM
AWS Serverless Application Model
https://aws.amazon.com/serverless/sam/

22. Get latest version of the PHP layer

23. Create cloudformation template

24. Add the following Lambda Layer

25. Create index.php

26. Create AWS S3 deployment bucket

27. Create Cloudformation stack

28. Deploy Cloudformation stack

29. Ok, but...

30. PHP community never sleep

31. Bref.sh

32. Bref Installation
Install using composer
Init a sample function

33. Bref Sample

34. Bref Sample

35. Bref Sample - template.yaml

36. Bref Sample - template.yaml

37. Bref Sample - index.php

38. Lambda run locally

39. Bref run locally

40. SAM uses docker
The docker container runs and die

41. SAM uses docker
type docker ps when you request the url to check it

42. Bref Deployment
Generate the stack configuration

43. Bref Deployment
Deploy the generated stack

44. Our lambda is deployed

45. Our lambda is deployed

46. API Gateway URL / test me
https://igodztg0s8.execute-api.us-east-1.amazonaws.com/Prod

47. Bref with Laravel and Symfony
