Architecture

a monolithic architecture

so far so good… but we started growing…

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

SOA

Service Oriented Architecture

– A.Nadalin (@_odino_)

“A software design based on discrete software components, "services", that collectively

provide the functionalities of the larger software application”

– A.Nadalin (@_odino_)– A.Nadalin (@_odino_)

– A.Nadalin (@_odino_)– A.Nadalin (@_odino_)

“Microservice Architecture" […] a particular way of designing software applications

as suites of independently deployable services…”

– M.Fowler

FULL STACK IS DEAD!

services as Lego bricks

Unix Philosophy

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

SOA Benefits

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

how do you connect services?

HTTP

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

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”

answered by 80% of candidates during the interview

“you don’t know HTTP? you shall not pass”

- Gandalf

Rabbitmq

using crons!

Rabbitmq

Rabbitmq

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!

PHP

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
