Route 53 da CloudFront su nawa?

Question

Accepted Answer

**Route 53** shine **DNS** na AWS (fassara sunan yanki zuwa adiresoshi, tare da jerin shawara na traffic); **CloudFront** shine **CDN** na AWS (Cibiyar Rarrabawa ta Abun Ciki, adana abun ciki a ƴaƴe na edge a duniya don karbar da sauri). Dukansu suna inganta aiki da kasuwanci ga aikace-aikacen gida.

## Route 53 — DNS da shirye-shiryen traffic

```text
Route 53 is a managed DNS service (+ domain registration):
  → translates domain names (example.com) → IP addresses / AWS resources
  → ROUTING POLICIES (intelligent traffic direction):
    - SIMPLE → one destination
    - WEIGHTED → split traffic by percentage (e.g. A/B testing, gradual rollout)
    - LATENCY → route users to the lowest-latency region (performance)
    - GEOLOCATION → route by user location
    - FAILOVER → route to a backup if the primary fails (HIGH AVAILABILITY)
  → HEALTH CHECKS → route away from unhealthy endpoints
```

## CloudFront — CDN (rarrabawa ta abun ciki)

```text
CloudFront is a Content Delivery Network — caches content at EDGE locations worldwide:
  → content served from an edge location NEAR the user → low latency, fast loads
  → caches static assets (images, CSS, JS, videos) close to users globally
  → reduces load on your origin (S3, EC2, ALB) — the edge serves cached content
  → also: DDoS protection, HTTPS, can serve dynamic content too
→ User → nearest CloudFront EDGE (cached?) → if miss, fetch from ORIGIN, then cache
```

## Ana amfani tare

```text
Route 53 (DNS) → points your domain at CloudFront (CDN) → which serves cached content
  from edges and fetches from origins (S3/ALB) on misses.
→ Common pattern for fast, global, highly-available web delivery.
```

## Menene mahimmancin haka

Ganewa ta Route 53 da CloudFront yana da kyau saboda suna abin komai don **aiki na aikace-aikacen gida da kasuwanci**, saboda haka ilimin AWS yana da amfani. **Route 53** (DNS) wuce kawai toshe sunan yanki - **jerin shawara na routing** yana ba da dali wajen gudanarwa na traffic: **routing da ya dogara ga latency** (tutar masu amfani zuwa yankin mafi kaushi-latency don aiki), **weighted routing** (rarraba traffic don jerin A/B ko saurin sauye-sauyewa), **failover routing** (tutar zuwa waje idan na farko ya gazawa, goyan bayan **kasuwanci** da dace), da **geolocation routing** — tare da shawo-shawowar lafiya da ke tutar jiya daga makwabishin marasa lafiya.

Wan ya sanya Route 53 karita don aiki (tutar masu amfani da kyau) da amincewa (failover). **CloudFront** (CDN) yana inganta **aiki** ta adana abun ciki a **yeren edge a duniya**, saboda abun ciki ana saita daga inda kusa da kowane mai amfani (tabbatarwa da sauri ga bayyana jiya a duniya) yayin da kuma **murmanin sakowa akan jiyya ta asali** (edge yana saita abun ciki da aka adana) da karfafa kamar kariya DDoS da HTTPS — abin mahimmanci don saita abubuwan da sauri zuwa audagin duniya.
