In 2026, a "good" app isn't just one that works; it’s one that scales. As first-year Computer Engineering students at SPPU, we are moving past the "Monolith"—where one big program handles everything—to Event-Driven Microservices. This is the high-performance architecture powering the world’s most resilient cloud platforms. 1. The Death of the "Wait" (Asynchronous Processing) In a traditional app, when a student scans a QR code for attendance, the app "waits" for the database to update before showing a success message. In an Event-Driven Architecture (EDA), the scan triggers an "Event." The Producer: The mobile app sends a "Scan Event" to a message broker (like Apache Kafka or AWS EventBridge). The Consumers: Multiple small services (Microservices) "listen" for that event. One updates attendance, another sends a push notification, and a third updates the teacher’s dashboard—all at the same time. 2. Serverless: Code Without Servers By using Serverless Computing (like AWS Lambda or
