🌍 AWS Regions

Region — dunyoning turli joylarida joylashgan AWS infratuzilmasining mustaqil geografik hududlari. Har bir region kamida 2-3 Availability Zone (AZ)dan iborat. Hozirda 30+ region mavjud. Region tanlashda: latency, compliance, pricing, available services ni hisobga oling.

🏢 Availability Zones (AZ)

AZ — region ichidagi alohida fizik data center (yoki bir nechta yaqin data centerlar). Har bir AZ past latency optik kabel bilan boshqa AZlarga ulangan. AZlar orasidagi masofa yetarlicha katta (zamonaviy ofatlar bir vaqtda ikki AZga ta'sir qila olmasligi uchun), lekin yetarlicha yaqin (past latency uchun).

⚡ Edge Locations & CloudFront

Edge Location — CloudFront CDN uchun cache punktlari. 400+ edge location mavjud. Foydalanuvchiga geografik jihatdan eng yaqin edge locationdan kontent yetkaziladi — bu latencyni kamaytiradi. Route 53 (DNS) ham edge locationlardan foydalanadi.

🔗 Global vs Regional vs AZ-level Services

Global: IAM, Route 53, CloudFront, WAF — regionga bog'liq emas
Regional: S3, DynamoDB, Lambda — region ichida replikatsiya
AZ-level: EC2 instance, EBS volume — bitta AZda

📊 Global vs Regional vs AZ-level Xizmatlar

Scope	Xizmatlar	Eslatma
🌍 Global	IAM, Route 53, CloudFront, WAF, Organizations	Region tanlamaysiz
🗺️ Regional	S3, DynamoDB, Lambda, SQS, SNS	Regionda replikatsiya
🏢 AZ-level	EC2 instance, EBS Volume, RDS (Single-AZ)	Bitta AZ da joylashgan

💡 Asosiy nuqtalar

Region > AZ > Data Center ierarxiyasi
Min 2 AZ, odatda 3 AZ har bir regionda
400+ Edge Location, 30+ Region
IAM, Route 53, CloudFront — global xizmatlar
AZ tanlash = High Availability uchun muhim

🎯 Imtihon maslahatlari

AZ vs Edge Location: AZ = compute/storage, Edge Location = CDN cache/DNS
CloudFront Edge Location soni Region sonidan ko'p (400+ vs 30+)
S3 regional xizmat, lekin globally accessible — S3 "global" emas!
Latency kamaytirish uchun: CloudFront (static) yoki Region tanlash (dynamic)
Compliance uchun Region tanlash: ma'lumotlar Region dan chiqmaydi (default)

⚠️ Ko'p adashadigan

Edge Location = AZ deb o'ylash. Xato! Edge Location — CDN cache, AZ — data center
S3 ni global xizmat deb hisoblash. S3 regional, lekin global URL ga ega
Multi-AZ = Multi-Region deb o'ylash. Bular farqli high availability darajalari

🧠 Eslab qolish: "Region > AZ > Data Center" — Mamlakat > Shahar > Bino. CloudFront Edge = Pochta bo'limi (eng yaqin joy)
