Menene sanannun tsarin gida AWS?

Question

Accepted Answer

Gina tsarin AWS da aka gida daidai yawa suna bin tsarin da aka tabbata — tsarin gida yanar gida mai kai uku, microservices, abubuwan da aka ba da haushi, babu aiki, da wasu — waɗanda suke haɗa abubuwan AWS don tugunar bukatun gida kamar faɗi, warrayowa, da tsanantswanci.

## Tsarin gida yanar gida mai kai uku (tsohuwa)

```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.
```

## Abubuwan da aka ba da haushi da babu aiki

```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)
```

## Sanannun tsarin taimako

```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
```

## Me ya sa haka yake da muhimmanci

Sanin sanannun tsarin gida AWS yana da mahimmanci a matsayin ilimin matakin babbar jiya don cewa **tsarin da aka tabbata suna samar da matsakaici da aka gwada ga bukatun gida gida** (faɗi, warrayowa, tsanantswanci), saboda sanin su yana taimakawa a zana tsarin da aka daidaita daidai sannu-sannu.
\'In kuwa ba tare da samuwa sabis sabis, waɗannan tsarin da aka tabbata suna haɗa abubuwan AWS ta hanyar da aka gwada don tugunar abubuwan da aka sauya.

**Tsarin gida yanar gida mai kai uku** (gabatarwa ta CloudFront/S3, aiki ta hanyar haɓaka multi-AZ amfani bayan ma'auni, data ta RJS/DynamoDB tare da ajiya) yana da asali scalable web pattern — ganin shi yana samar da sarariya mai aiki ga abubuwan yanar gida. **Microservices** (warwarewa zuwa ayyuka masu zaman kansu tare da su nasu data, za su yi magana ta hanyar APIs da da asynchronous messaging) yana ba da damar kawar daban-daban, aiki, da zaman kansu na ƙungiya ta yadda haka cikin ragagazzabo cikin hadde — mahimmanci don tsarin masu girma. **Abubuwan da aka ba da haushi da babu aiki** (abubuwan da suke amfani da abubuwan ta hanyar EventBridge/SNS/SQS, ko kuma tsarin babu aiki gabaɗaya) suna samar da tsarin da ba a raba, mai tsanantswanci, da ba mafi dacewa don yawancin bukatun zamani.
