🏗️ AWS Well-Architected Framework
Cloud architecture design र optimization को लागि AWS को best practice guidelines — 6 Pillars मा बाँडिएको छ।

1️⃣ Operational Excellence
"कसरी अझ राम्रोसँग चलाउने?"
|
|
📖 सजिलो भाषामा:
System चलाउँदा गल्ती हुनेछ — त्यो गल्तीलाई छिटो detect गरेर, fix गरेर, process सुधार्ने काम। जस्तै restaurant ले complaint आएपछि recipe नै सुधार्छ।
|
|
🔑 Key Services/Concepts:
▸ Infrastructure as Code — manual click होइन, code बाट infra बनाउने (CloudFormation)
▸ Automated deployments — CI/CD pipeline
▸ Monitor & respond — CloudWatch alerts
|
|
🎯 Exam Clue: Infrastructure as Code / Automated deployment → Operational Excellence
|
|
|
2️⃣ Security
"कसरी सुरक्षित राख्ने?"
|
|
📖 सजिलो भाषामा:
Data चोरी नहोस्, unauthorized access नहोस् भनेर गरिने सबै काम। जस्तै घरमा ताल्चा, CCTV, guard राख्नु।
|
|
🔑 Key Services/Concepts:
▸ IAM — को कसलाई के access छ
▸ Least Privilege — जति चाहियो त्यति मात्र permission
▸ Encryption — KMS, CloudHSM
▸ Monitor events — CloudTrail, GuardDuty
|
|
🎯 Exam Clue: IAM / Encryption / Least privilege → Security pillar
|
|
|
3️⃣ Reliability
"कसरी down नगराउने?"
|
|
📖 सजिलो भाषामा:
Website/app कहिल्यै down नहोस्, problem आए पनि आफैं ठीक होस् भन्ने। जस्तै बिजुली गयो भने generator automatically start हुनु।
|
|
🔑 Key Services/Concepts:
▸ Multi-AZ deployment — एक AZ fail भए अर्कोले handle गर्छ
▸ Auto recovery — problem detect भएपछि automatic fix
▸ Backup & Disaster Recovery — data loss हुँदैन
|
|
🎯 Exam Clue: Multi-AZ / Disaster Recovery / High Availability → Reliability
|
|
|
4️⃣ Performance Efficiency
"कसरी fast र efficient बनाउने?"
|
|
📖 सजिलो भाषामा:
सही काम को लागि सही resource चुन्ने। 10 जना customer को लागि 100 server waste हो — ठ्याक्कै चाहिने जति resource use गर्ने।
|
|
🔑 Key Services/Concepts:
▸ Right instance type — workload अनुसार EC2 type choose
▸ Auto-scaling — traffic बढ्यो भने server थप्ने, घट्यो भने हटाउने
▸ Global reach — CloudFront, Edge Locations
|
|
🎯 Exam Clue: Right instance / Auto-scaling / Speed optimization → Performance Efficiency
|
|
|
5️⃣ Cost Optimization
"कसरी पैसा बचाउने?"
|
|
📖 सजिलो भाषामा:
नचाहिने resource मा पैसा नखर्चने। जस्तै रात भर बत्ती बाल्नु — waste। Use नगरिरहेको server बन्द गर्नु = cost save।
|
|
🔑 Key Services/Concepts:
▸ Right sizing — over-provisioning नगर्ने
▸ Reserved Instances — 1-3 year commit = 72% discount
▸ Cost monitoring — AWS Cost Explorer, Budgets
|
|
🎯 Exam Clue: Right sizing / Reserved Instances / Save money → Cost Optimization
|
|
|
6️⃣ Sustainability
"कसरी environment friendly बनाउने?"
|
|
📖 सजिलो भाषामा:
Cloud use गर्दा बिजुली खर्च हुन्छ, carbon emit हुन्छ। त्यो कम गर्ने। सबैभन्दा नयाँ pillar (2021 मा थपिएको)।
|
|
🔑 Key Services/Concepts:
▸ Energy-efficient regions — renewable energy भएको region छान्ने
▸ Optimize utilization — idle resource हटाउने
▸ Reduce waste — Serverless use गर्ने
|
|
🎯 Exam Clue: Environmental impact / Carbon / Energy efficient → Sustainability
|
|
|
🔥 Confusion Buster — यी दुईको फरक!
|
| Topic |
Performance Efficiency |
Cost Optimization |
| Focus |
Speed र efficiency — Fast हुनु पर्छ |
Money save — Cheap हुनु पर्छ |
| Auto Scaling |
✔ Performance को लागि |
✔ Cost को लागि पनि (idle server हटाउँछ) |
| Right Sizing |
Right type छान्ने (speed focus) |
Right size छान्ने (cost focus) ← exam मा Cost मा आउँछ |
