AWS NETWORKING — GLOBAL PERFORMANCE

🌐 AWS Global Accelerator

User traffic लाई AWS को private global network मार्फत नजिकको edge location हुँदै छिटो र stable तरिकाले application सम्म पुर्‍याउने service।

🔤 STEP 1 — Global Accelerator भनेको के हो? Foundation देखि

✈️ Nepal Analogy — Kathmandu → London

Normal Internet: Kathmandu बाट London को letter पठाउँदा कति ठाउँ-ठाउँ हुँदै जाँदा ढिलो हुन्छ, बाटो बिग्रन सक्छ।

Global Accelerator: Kathmandu को नजिकको AWS Edge (Mumbai) सम्म मात्र public internet — त्यसपछि AWS को आफ्नै super-fast private highway!

→ Public internet कम प्रयोग = Fast + Stable!

💻 Tech मा के गर्छ?

▸ 2 Static IP addresses दिन्छ — globally same IP

▸ User को नजिकको Edge Location मा traffic लिन्छ

▸ AWS को private backbone मार्फत destination मा पठाउँछ

▸ Endpoint down भयो = automatic failover

→ Layer 4 (TCP/UDP) — HTTP मात्र होइन!

🗺 STEP 2 — कसरी काम गर्छ? Flow Diagram (Nepal Context)

🔑 STEP 3 — Key Features — यो 100% Exam मा आउँछ!

Feature के गर्छ? Exam Key
🌐 2 Static IP DNS change नगरी backend बदल्न मिल्छ। Globally same 2 IP। ⭐ Static IP = Global Accelerator (100%)
🛣️ Private Network Public internet bypass। AWS को आफ्नै backbone highway प्रयोग। Low latency + Stable = Private network
🔄 Auto Failover Endpoint down = automatically healthy endpoint मा switch। < 30 seconds। High availability = Auto failover
📍 Edge Location User को नजिकको edge location मा traffic लिन्छ → latency घट्छ। Nearest edge = Latency कम
🔀 TCP/UDP Layer 4 (Network layer) — HTTP मात्र होइन, gaming/IoT/video call पनि। ⭐ Non-HTTP / TCP/UDP = Global Accelerator

🔥 Global Accelerator vs CloudFront vs Route 53 — Confusion Buster (100% EXAM)
Feature 🌐 Global Accelerator 🟠 CloudFront 🟣 Route 53
के हो? Network traffic accelerator Content Delivery Network (CDN) DNS service
Layer Layer 4 (TCP/UDP) Layer 7 (HTTP/HTTPS) DNS Level
Caching? ❌ No caching ✔ Yes — content cache गर्छ ❌ No caching
Static IP? ✔ 2 Static IPs ❌ No (DNS name) ❌ No (DNS name)
Nepal Use Case Esewa gaming app — low latency TCP Daraz product images cache esewa.com DNS routing
Keyword Static IP / TCP/UDP / Low latency / Non-HTTP Cache / CDN / Static content / HTTP DNS / Domain routing / Failover DNS

❓ MCQ Practice — Exam Style
Question Answer
Q1. Company needs 2 static IP addresses that route to multiple regions. Which service?
A) CloudFront   B) Route 53   C) Global Accelerator   D) ALB		 C ✔
Global Accelerator
Q2. Company wants to cache static content globally. Which service?
A) Global Accelerator   B) Route 53   C) CloudFront   D) ELB		 C ✔
CloudFront (Accelerator होइन!)
Q3. A gaming app needs low latency TCP connections globally. Which service?
A) CloudFront   B) Route 53   C) Global Accelerator   D) SQS		 C ✔
Global Accelerator (TCP = Layer 4)
Q4. ⭐ Tricky — One region endpoint goes down, traffic automatically routes to healthy region. Same IP maintained. Which?
A) Route 53   B) CloudFront   C) Global Accelerator   D) NLB		 C ✔
Global Accelerator (Same IP + Failover)
Q5. ⭐ Tricky — Non-HTTP application (UDP-based video streaming) global performance चाहिन्छ। Which?
A) CloudFront   B) Global Accelerator   C) Route 53   D) API Gateway		 B ✔
Global Accelerator (CloudFront HTTP मात्र!)

⚡ FINAL EXAM CHEATSHEET — 5 Second Answer
Keyword देख्यौ Answer किन?
Static IP / 2 IPs / Same IP globally 🌐 Global Accelerator 2 Static IP = GA को unique feature
TCP/UDP / Non-HTTP / Gaming / IoT / Low latency 🌐 Global Accelerator Layer 4 — CloudFront ले TCP/UDP गर्दैन
Cache / CDN / Static files / HTTP/HTTPS content 🟠 CloudFront (GA होइन!) Cache = CloudFront, Accelerate = GA
DNS routing / Domain / Geo routing 🟣 Route 53 (GA होइन!) DNS = Route 53, Network = GA
⭐ Region fails, same IP, auto failover (<30s) 🌐 Global Accelerator IP change नगरी failover = GA को specialty
