Today’s world is ultra-connected 🕸️
Most computer systems/web services that you can use daily are not one application but a set of applications that interact with each other.
First use case¶
A student answers an online satisfaction survey and after submitting their questionnaire automatically receives a personalized and specific response based on their answers.
A second use case¶
❓ What ingredients, tools 🛠️ need to be implemented?❓
👩🍳 The necessary ingredients 👨🍳¶
Applications that can contact each other,
exchange data
with clearly established rules allowing to trigger actions
In this course¶
We will try to answer the following questions
How to communicate between two applications on a network?
How to send a message from one application to another via the network?
In what format should this message be sent?
How do we make a Python application capable of listening on the network?
Architecture¶
To make applications collaborate together, there are many different models and architectures
We will look at the most classic ones
Client-server¶
Three-tier architecture¶
Peer-to-peer architecture¶
Very fashionable at a time when Netflix/Amazon Prime/... didn’t exist (yes yes this period is real 🤯)

The Web¶
Just a big network
