AWS CLOUD ARCHITECTURE

🏗️ AWS Well-Architected Framework

Cloud architecture design र optimization को लागि AWS को best practice guidelines — 6 Pillars मा बाँडिएको छ।

🧠 6 PILLARS याद राख्ने TRICK — "OS RPCS"

Excellence		 Security Reliability Performance
Efficiency		 Cost
Optimization		 Sustain-
ability

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
