Event-Driven Architecture: A design pattern where services communicate by emitting and responding to events asynchronously.

Key Components:

• Event Producer: Generates events (e.g., a user uploads a file).
• Event Consumer: Listens and reacts to events (e.g., a service processes the uploaded file).
• Message Broker: Facilitates event delivery (e.g., Kafka, RabbitMQ).

When to Use:

• Applications needing real-time updates (e.g., chat apps, stock trading platforms).
• Decoupled microservices to enhance scalability and maintainability.
• Workflows with asynchronous tasks (e.g., order processing).
