Pira carane nggawe arsitektur serverless ing AWS?

Question

Accepted Answer

**Serverless architecture** mbangun aplikasi saka layanan sing dikelola, didorong acara (Lambda, API Gateway, DynamoDB, S3, SQS, dll.) tanpa ngatur server — AWS nangani penskalaan lan infrastruktur. Ngerti cara nggawe sistem serverless lan pertukaran-pertukaran (trade-off) e iku ilmu sing penting kanggo arsitektur cloud modern.

## Arsitektur serverless sing khas

```text
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.
```

## Prinsip desain serverless

```text
✓ EVENT-DRIVEN — components react to events (HTTP, queue messages, S3 events, schedules)
✓ Small, single-purpose FUNCTIONS (Lambda does one thing well)
✓ STATELESS functions — state lives in databases/storage (functions are ephemeral)
✓ Use MANAGED services for everything (database, auth, messaging) — no servers anywhere
✓ Decouple with queues/events for resilience and async processing
```

## Manfaat lan pertukaran

```text
✓ NO server management; AUTO-SCALING (to zero and to huge); PAY-PER-USE (cheap at low/
  variable load); fast to build; high availability built in
✗ COLD STARTS (latency); execution limits (Lambda 15 min); complexity in distributed
  debugging/tracing; potential vendor lock-in; can cost more at very high constant scale
→ Great for: variable/bursty/event-driven workloads, APIs, automation, rapid development.
  Less ideal: long-running, constant heavy compute, very latency-sensitive (cold starts).
```

## Dene iku penting

Ngerti cara nggawe arsitektur serverless iku ilmu tingkat senior sing penting amarga serverless minangka cara penting lan berkembang kanggo mbangun aplikasi cloud, mula ngerti desain lan pertukaran-pertukaran e iku migunani kanggo keputusan arsitektur modern.

Cara serverless — mbangun aplikasi saka **layanan sing dikelola, didorong acara** (Lambda kanggo logika, API Gateway kanggo HTTP, DynamoDB kanggo data, S3 kanggo panyimpenan, SQS/SNS/EventBridge kanggo messaging, Cognito kanggo autentikasi) **tanpa ngatur server** — makili perubahan paradigma arsitektur sing signifikan neng AWS nangani kabeh penskalaan lan infrastruktur, eling tim kanggo fokus murni ing logika aplikasi.

Ngerti **arsitektur serverless sing khas** (cara layanan-layanan iki digabung dadi aplikasi lengkap) lan **prinsip desain** (komponen didorong acara, fungsi kecil stateless tujuan tunggal, nggunakake layanan sing dikelola kabeh, nglepokaké karo antrian/acara) iku kudu kanggo nggawe sistem serverless kanthi becik.

Kritisalé, ngerti **manfaat lan pertukaran** iku penting kanggo keputusan sing sae: manfaat (ora ana pangurus server, penskalaan otomatis kalebu menyang nul, efisiensi biaya bayar-per-panggunaan ing beban variabel, pengembangan cepet, ketersediaan tinggi sing mbangun dhewe) nggawe serverless sing apik kanggo beban variabel, bersit, lan acara, API, lan pengembangan cepet — nalika pertukaran (latensi wiwit dingin, watesan eksekusi, kompleksitas debug sistem terdistribusi, potensi gembok vendor, lan bisa uga biaya luwih dhuwur ing skala tetap dhuwur banget) teges iku kurang kanggo pangalihan jangka panjang, komputasi tetap dhuwur, utawa beban-kerja sensitif latensi sing banget.

Ngerti **nalika serverless sing pas** (lan nalika iku ora) nggambarake pamikiran arsitektur sing mateng.

Amarga serverless minangka cara utama modern kanggo aplikasi cloud (menawarake manfaat sing narik kanggo beban-kerja sing pas) lan nggawe sistem serverless kanthi becik nggaké ngerti layanan, prinsip desain, lan utamané pertukaran-pertukaran, ngerti arsitektur serverless ing AWS iku ilmu tingkat senior sing penting kanggo arsitektur cloud modern — paradigma sing saya-saya dadi penting neng ndene ngerti kekuwatan lan watesan-e ngaktifake milih lan nggawe solusi serverless kanthi wajar, nggambarake jembar arsitektur sing dikarepake kanggo peran cloud senior.
