Pola arsitektur AWS apa kang umum?

Question

Accepted Answer

Membangun sistem AWS sing dirancang kanthi apik asring ngetutake pola sing wis mapan — arsitektur wèb ping telung tingkat, microservices, event-driven, serverless, lan liyane — sing nggabungake layanan AWS kanggo ngatasi kebutuhan umum kaya skalabilitas, decoupling, lan resiliensi.

## Arsitektur wèb ping telung tingkat (klasik)

```text
The classic scalable web app:
  PRESENTATION → CloudFront (CDN) + S3 (static frontend) or ALB → web tier
  APPLICATION → EC2/containers (auto-scaled, multi-AZ) behind a load balancer
  DATA → RDS (Multi-AZ) / DynamoDB; ElastiCache for caching
→ Each tier scales independently; multi-AZ for HA; the foundational web pattern.
```

## Microservices

```text
Decompose into independent services (each owning its data):
  → containers (ECS/EKS) or Lambda per service; API Gateway / service mesh
  → communicate via APIs and async messaging (SQS/SNS/EventBridge)
  → independent scaling, deployment, and teams
→ Flexibility and scalability at the cost of distributed-system complexity.
```

## Event-driven lan serverless

```text
EVENT-DRIVEN → components react to events via EventBridge/SNS/SQS:
  → decoupled, async, resilient; producers and consumers independent
  → e.g. S3 upload → Lambda processes → writes to DynamoDB → SNS notifies
SERVERLESS → API Gateway + Lambda + DynamoDB + S3 (no servers, auto-scale, pay-per-use)
```

## Pola pendukung umum

```text
✓ CACHING → ElastiCache/CloudFront to reduce load and latency
✓ QUEUE-BASED load leveling → SQS buffers spikes; consumers process steadily
✓ FAN-OUT → SNS → multiple SQS/Lambda (parallel independent processing)
✓ CQRS, database-per-service, circuit breakers, retries with backoff
✓ MULTI-AZ everything (HA); IaC for everything; decouple for resilience
```

## Mengapa iki penting

Mangerteni pola arsitektur AWS sing umum minangka pengetahuan tingkat senior sing berharga amarga **pola sing wis nyukupi nyediyake solusi sing wis dites kanggo kebutuhan umum** (skalabilitas, decoupling, resiliensi), dadi ngerti bab iki nduweni tulung ngrancang sistem sing dirancang kanthi apik kanthi efisien.

Sanadyan ora kudu ngrancang arsitektur maneh, pola sing wis mapan iki nggabungake layanan AWS kanthi cara sing wis nyukupi kanggo ngatasi kabutuhan sing bola-bali.

**Arsitektur wèb ping telung tingkat** (presentasi via CloudFront/S3, aplikasi via komputasi ping multi-AZ otomatis di mburi load balancer, data via RDS/DynamoDB karo caching) minangka pola dasar skalabel kanggo wèb — mangerteni iki nyediyake template sing ati-ati kanggo aplikasi wèb. **Microservices** (ngrombaka dadi layanan mandiri karo data dhewe, komunikasi via API lan asynchronous messaging) ngidini skalabilitas mandiri, deployment, lan otonom tim ing balas malayang babagan kerumitan terpilah — penting kanggo sistem sing luwih gedhe. **Pola event-driven lan serverless** (komponen sing tumungga marang acara via EventBridge/SNS/SQS, utawa stack serverless lengkap) nyediyake arsitektur sing terpisah, resilient, skalabel sing cocok kanggo akeh kabutuhan modern.

Mangerteni **pola pendukung** (caching kanggo ngurangi beban, queue-based load leveling kanggo nyerap loncatan, fan-out kanggo pangolahan paralel, ditambah prinsip kaya multi-AZ kabeh kanggo HA, IaC kanggo kabeh, lan decoupling kanggo resiliensi) nyediyake perangkat teknik sing wis nyukupi.

Ngerti pola-pola iki — lan kapan saben-saben ngarepake — nduweni tulung ngrancang sistem sing skalabel, resilient, lan dirancang kanthi apik kanthi ngetrapake solusi sing wis dites sanadyan mangerteni tukaran isi nduweni tulung milih sing pas.

Karana ngrancang sistem cloud kanthi apik luwih gampang lan luwih dipercaya nalika ngetrapake pola sing wis nyukupi (kanggo skalabilitas, decoupling, resiliensi) sanadyan ora kudu ngrancang arsitektur maneh, lan karana mangerteni pola AWS sing umum lan tukar isi iki ngidini desain arsitektur sing efisien lan sehat, mangerteni pola arsitektur AWS sing umum minangka pengetahuan tingkat senior sing berharga kanggo arsitektur cloud — perangkat solusi sing wis dites sing, digabung karo prinsip Well-Architected, ngidini ngrancang sistem AWS sing kuat, ngrefleksike pengalaman arsitektur lan pertimbangan sing dikira-kira kanggo peran cloud senior.
