Serverless architecture ले managed, event-driven services (Lambda, API Gateway, DynamoDB, S3, SQS, आदि) बाट servers को व्यवस्थापन गरी अनुप्रयोग निर्माण गर्छ — AWS ले scaling र infrastructure को व्यवस्थापन गर्छ। Serverless प्रणालीहरू कसरी डिजाइन गर्ने र तिनका trade-offs बुझ्नु आधुनिक cloud architecture को लागि मूल्यवान छ।
एक सामान्य 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.
