Could you tell me about different types of application architectures you've encountered?

Among the application architectures I have encountered, the following popular types can be distinguished:

• Monolithic architecture — a traditional approach where all components are tightly coupled and deployed together. Suitable for small projects but hard to scale.
• Client-server architecture — separation into client part (e.g., web interface) and server that handles logic and data.
• Microservices architecture — application is divided into independent services communicating via APIs. Easier to scale and maintain but requires complex infrastructure.
• MVC (Model-View-Controller) — separates data model, presentation, and control logic. Common in web apps.
• Event-driven architecture — components interact through events, enabling flexible and scalable systems.

Example of simple MVC in Python with Flask:

from flask import Flask, render_template
app = Flask(__name__)

# Model
users = ['Alice', 'Bob', 'Charlie']

# Controller
@app.route('/')
def index():
    return render_template('index.html', users=users)

if __name__ == '__main__':
    app.run()

Here, the model is a list of users, the controller is the index function, and the view is an HTML template.
