Modern networking is no longer limited to physical devices and local servers.
👉 Everything is moving to the Cloud.
From websites to enterprise systems—cloud computing is now the backbone of the internet.
🔍 What is Cloud Computing?
Cloud Computing is the delivery of computing services over the internet.
Instead of:
Owning physical servers
You use:
Remote servers hosted in data centers
⚙️ How Cloud Computing Works
User connects to cloud service
Request is sent over internet
Cloud servers process it
Response is returned
All happens in real time.

IaaS (Infrastructure as a Service)
Virtual servers
Example: AWS EC2
PaaS (Platform as a Service)
Development platforms
Example: Google App Engine
SaaS (Software as a Service)
Ready-to-use apps
Example: Gmail, Office 365
🌐 Types of Cloud Deployment
Public Cloud
