Ailtireacht gan fhreastalaí tógann feidhmchláranna ó sheirbhísí bhainistíochta, bhogtha ar imeall (Lambda, API Gateway, DynamoDB, S3, SQS, etc.) gan fhreastalaí a bhainistiú — láimhdeálann AWS an scálú agus an bhonneagar. Tuiscint ar conas córais gan fhreastalaí a dhearadh agus a gcomhthuillí a bhainistiú is luachmhar do ailtireacht scamall nua-aimseartha.
Ailtireacht typicial gan fhreastalaí
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.
