🗺️ Cloud Adoption Framework (CAF)

AWS CAF — cloud ga o'tish uchun strategik framework. 6 ta Perspective: Business, People, Governance (biznes tomon) + Platform, Security, Operations (texnik tomon). CAF — tashkilotning cloud readiness ni baholash va roadmap yaratish uchun.

🔄 7R Migration Strategiyasi

Retire — keraksiz applarni o'chirish
Retain — hozircha on-premises da qoldirish
Rehost (Lift & Shift) — o'zgartirishsiz ko'chirish
Replatform — kichik optimizatsiya bilan (managed service)
Repurchase — SaaS ga o'tish (Salesforce, Workday)
Refactor — cloud-native qayta yozish (maksimal afzallik)
Relocate — VMware Cloud on AWS

❄️ AWS Snow Family

Snowcone — 8 TB, eng kichik, edge computing. Snowball Edge — 80 TB, offline migration + compute. Snowmobile — 100 PB, 18-g'ildirakli yuk mashinasi, exabyte scale. Internet imkoni cheklangan yoki juda katta migratsiyalar uchun.

🚀 AWS AI/ML & Innovation Services

Rekognition — rasm/video tahlil. Comprehend — NLP, sentiment analysis. Translate — real-time tarjima. SageMaker — end-to-end ML platform. Bedrock — Foundation Models API. QuickSight — serverless BI. Connect — cloud contact center.

📊 Snow Family Taqqoslash

Qurilma	Hajm	Edge Compute	Use Case
Snowcone	8 TB	Ha (2 vCPU)	Field, remote, kichik migratsiya
Snowball Edge Storage	80 TB	Ha (52 vCPU)	Offline migratsiya, backup
Snowball Edge Compute	42 TB	Ha (GPU)	ML inference at edge
Snowmobile	100 PB	Yo'q	Exabyte scale data center ko'chirish

💡 Asosiy nuqtalar

CAF: Business+People+Governance (biznes) + Platform+Security+Operations (texnik)
7R: Retire, Retain, Rehost, Replatform, Repurchase, Refactor, Relocate
Rehost = tez, Refactor = eng ko'p afzallik
Snow Family: offline, katta hajmli migratsiya
SageMaker = ML platform, Bedrock = Foundation Models

🎯 Imtihon maslahatlari

Rehost = tez migratsiya, cloud afzalliklaridan foydalanmaydi
Refactor = qimmat, lekin scalability, resilience eng yuqori darajada
"10 Gbps internet, 100 TB" → Snow Family internet dan tezroq va arzonroq
CAF — texnik tool EMAS, strategik framework (C-level uchun)
Bedrock = Foundation Models API (Claude, Llama, Titan) — CLF-C02 da yangi mavzu

⚠️ Ko'p adashadigan

Replatform va Refactor: Replatform = kichik o'zgartirish (masalan, EC2 → RDS), Refactor = to'liq qayta yozish
Snow Family = faqat backup deb o'ylash — asosiy maqsad migratsiya va edge compute
CAF va Well-Architected Framework ni aralashtirib yuborish: CAF = migratsiya strategiyasi, WAF = architecture best practices

🧠 Eslab qolish: "7R" = Retire, Retain, Rehost, Replatform, Repurchase, Refactor, Relocate. "Snow: Cone < Ball < Mobile" — kichikdan kattaga. "SageMaker = ML, Bedrock = GenAI"
