Serverless architecture servers को प्रबंधित किए बिना प्रबंधित, event-driven सेवाओं (Lambda, API Gateway, DynamoDB, S3, SQS, आदि) से applications बनाता है — AWS scaling और infrastructure संभालता है। serverless systems कैसे डिज़ाइन करें और उनके trade-offs को समझना आधुनिक cloud architecture के लिए मूल्यवान है।
एक विशिष्ट serverless architecture
A serverless web app/API often combines:
API GATEWAY → receives HTTP requests, routes to Lambda (the API entry point)
LAMBDA → functions handle the business logic (run on demand, auto-scale)
DYNAMODB → serverless NoSQL database (scales automatically)
S3 → static assets / file storage (host the frontend, store uploads)
COGNITO → managed authentication
SQS/SNS/EventBridge → async messaging and event-driven flows
CLOUDFRONT → CDN for the frontend
→ No servers to manage; everything scales automatically; pay per use.
