What is Cloud Computing?
🔹 Definition (Paribhasha):
Cloud Computing ka matlab hai internet ke through computing services provide karna – jaise ki servers, storage, database, networking, software, etc.
Aapko koi physical hardware lene ki zarurat nahi hoti, sab kuch online milta hai.
Jaise normally aap software apne computer par install karte ho ya files local hard drive mein rakhte ho, lekin cloud computing mein aap sab kuch internet ke through access karte ho – kahin se bhi, kabhi bhi.
🔹 Real-Life Example (Asli Zindagi Ka Example):
Socho jaise electricity hoti hai:
- Aapko apna power plant nahi banana padta
- Sirf plug lagao aur meter ke hisaab se bill bhar do
- Waise hi cloud computing mein bhi:
- Aapko khud ka server kharidne ki zarurat nahi
- Aap services jaise AWS (Amazon Web Services), Google Cloud ya Microsoft Azure ka use kar sakte ho
- Aur jitna use karo, utna hi paisa do — pay as you go
🔹 Cloud Computing Ki Features (Khaas Baaten):
- On-Demand Self-Service: Khud hi turant storage ya server le sakte ho — bina kisi manual help ke.
- Scalability: Zarurat ke hisaab se resources ko badhana ya ghatana asaan hai.
- Pay-as-you-go: Sirf jitna use karo utna hi paisa do. Koi extra investment nahi.
- Global Access: Kahin se bhi apne data aur apps ko access kar sakte ho.
- Automatic Updates: Security aur software updates ka dhyan provider khud rakhta hai.
🔹 Cloud Services Ke Types (Cloud Stack):
| Model | Full Form | Use |
|---|---|---|
| IaaS | Infrastructure as a Service | Virtual servers, storage wagairah milte hain. (Ex: AWS EC2) |
| PaaS | Platform as a Service | App banane aur run karne ka platform milta hai. (Ex: Google App Engine) |
| SaaS | Software as a Service | Ready-made software online chala sakte ho. (Ex: Gmail, Google Docs, Canva) |
🔹 Cloud Deployment Ke Types:
- Public Cloud: Multiple log ek hi system use karte hain (Example: AWS)
- Private Cloud: Sirf ek company ya organization ke liye hota hai — zyada secure.
- Hybrid Cloud: Public + Private ka combination — best of both worlds.
🔹 Popular Cloud Providers:
- Amazon Web Services (AWS)
- Microsoft Azure
- Google Cloud Platform (GCP)
- IBM Cloud
- Oracle Cloud
🔹 Cloud Computing Ka Use Kahaan Hota Hai? (Use Cases):
- Website aur apps host karna
- Online file storage (jaise Google Drive, Dropbox)
- Streaming services (Netflix bhi AWS par chalta hai)
- Badi-badi databases ko run karna
- Machine Learning aur AI ke liye
- Backup aur disaster recovery
🔹 Faayde aur Nuksaan (Pros & Cons):
- ✅ Faayde (Pros):
- Sasta padta hai (Cost-effective)
- Easily scale ho sakta hai
- Kahin se bhi access milta hai
- Updates aur maintenance automatic hota hai
- Secure hai (agar sahi tarike se setup kiya ho)
- ❌ Nuksaan (Cons):
- Internet connection chahiye
- Data privacy provider ke control mein hoti hai
- Agar usage monitor na karo toh mehenga pad sakta hai
✅ Summary (Saar):
Cloud computing ek aisa naya tareeka hai jisme aap bina khud ka computer ya server banaye computing power ka use kar sakte ho. Ye cost bachaata hai, flexible hai, aur aap technology ka use pe focus kar sakte ho — usse manage karne ke chakkar mein nahi padte.
