What is Event-driven Architecture?
A design pattern where components communicate by producing and reacting to events rather than direct calls.
Why It Matters
Event-driven systems are more flexible and scalable because components are loosely coupled and can evolve independently.
Real-World Example
When an order is placed, an event triggers separate processes for payment, inventory, and shipping notification.
“Understanding terms like Event-driven Architecture matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
