This document discusses Namshi's transition from a monolithic PHP architecture to a microservices architecture using PHP, Node.js, and other technologies. Some of the benefits realized include improved scalability, deployability, and maintainability. Key aspects covered include the use of service-oriented architecture with independent services, HTTP as the communication protocol, RabbitMQ for messaging, and PHP frameworks like Silex for building APIs. The new architecture also aims to be stateless, using JSON Web Tokens for authentication.

1. PHP is the king,
nodejs is the prince,
Lua is the fool

16. architecture

17. a monolithic architecture

18. so far so good… but we started growing…

19. “we need a brand new feature for the warehouse…”

20. SOA

21. Service Oriented Architecture

22. “A software design based on discrete software
components, "services", that collectively
provide the functionalities of the larger
software application”
– A.Nadalin (@_odino)

23. “Microservice Architecture" […] a particular way of
designing software applications as suites of
independently deployable services…”
– M.Fowler

Full Stack is dead!

24. services as Lego bricks

25. Unix philosophy
“Write programs that do one thing and do it well.”

26. SOA benefits
scalability
avoid single point of failure
easier and faster deploys
isolation
maintainability
easier to replace existing parts

27. How do you connect services?

28. HTTP
A protocol that is almost 25 years old
and is here to stay!

29. GET vs POST
“The difference is that in
a GET request you have the parameters in the url ,
with
a POST the parameters are in the request’s body”

you shall not pass” !

36. RabbitMQ

37. RabbitMQ
Language and protocol format agnostic
You can easily create an event driven architecture
Messages stay in the queue if a service goes down
Too many messages? add more consumers!

38. PHP

39. PHP -
It follows standards (PSR-*)
Decoupled components
Huge and active opensource community
Easy to plug in your domain code
Not just a framework, but a project…
Designed starting from the HTTP protocol

40. PHP -
bundle -> app -> service

41. PHP -
UserBundle
WarehouseBundle
CheckoutBundle
ProductBundle
[…]

42. Once you have a SOLID set of api
foundation you can easily start building
other awesome applications

43. PHP - Silex
the PHP micro-framework based on
Symfony2 Components
