System Design in Real Life: Why Ancient Museums are actually Microservices?

#systemdesign #architecture #beginners #discuss

Hello everyone! 👋

I have a bit of an unusual background. I work as a Backend Developer (Java/Spring), but I am also a university student studying Museology.

While studying the physical security layers of modern museums, I realized something mind-blowing: Museums use the exact same architecture as modern cloud software.

I couldn't unsee the patterns, so I decided to reverse-engineer a museum layout to explain System Design concepts.

Here is a 2-minute visual essay I made about this discovery:

🏛️ The Architecture Breakdown

For those who prefer reading, here is the logic behind the analogy:

1. Monolith vs. Microservices

The Old Way (Monolith): Ancient temples were single, massive structures. A fire in one room meant the whole building (system) collapsed.
The New Way (Microservices): Modern museums have separate wings (Egyptian Hall, Renaissance Hall). If security is breached in one hall, the others seal themselves off. The system remains active.

2. The API Gateway (Ticket Booth)

You can't just walk into a museum. You pass through a turnstile or ticket booth.

It verifies your identity.
It checks your ticket (Token).
It routes you to the entrance. Just like an API Gateway managing traffic before it hits the services.

3. The Database (The Vault)

The most valuable items aren't on display; they are in the underground vault.

Visitors (Users): Cannot access the vault directly.
Curators (Backend Services): Are the only ones with clearance to retrieve items. This is exactly how we protect our Databases from direct user access.

🦉 Why does this matter?

I believe looking at physical systems helps us understand abstract code better. Whether it's 2000-year-old history or a Spring Boot application, the security logic remains the same: Defense in Depth.

Let me know what you think about this analogy! Which other real-life systems remind you of coding patterns?
