Architectural Patterns & Principles
Learn to design high-performance architectures using proven patterns and industry best practices.
Core Architectural Patterns
🧩
Microservices
Decompose monolithic applications into independently deployable, loosely coupled services for scalable architecture.
🔁
Event-Driven
Build asynchronous architectures using event streams for scalable, decoupled system interactions.
🔁
CQRS
Separates command and query operations to optimize performance and simplify distributed systems.
Architectural Best Practices
| Principle | Implementation |
|---|---|
| Scalability | Implement stateless services with horizontally scalable architectures |
| Fault Tolerance | Design with retries, fallback mechanisms, and circuit breakers |
| Consistency | Use distributed transactions or eventual consistency patterns |
Architecture Example
// Example of an event-driven architecture
class EventAggregator {
constructor() {
this.handlers = new Map();
this.broker = new MessageBroker();
}
registerHandler(eventName, handler) {
this.handlers.set(eventName, handler);
}
async publish(eventName, payload) {
const handler = this.handlers.get(eventName);
if (handler) {
await handler(payload);
} else {
await this.broker.publish(eventName, payload);
}
}
}
