What is Cloud Computing?
Cloud computing delivers computing services—servers, storage, databases, networking, software, and more—over the internet (“the cloud”). It enables on-demand access to IT resources without upfront infrastructure investment.
Key characteristics:
On-demand self-service – Resources available when needed.
Scalability – Easily scale resources up or down.
Pay-as-you-go – Pay only for what you use.
Global access – Services are available worldwide.
Learn more about Cloud Computing on IBM Docs.
Types of Cloud Computing
Cloud computing comes in three primary deployment models:
Public Cloud – Services delivered over the public internet (e.g., AWS, Azure, GCP).
Private Cloud – Used by a single organization, offering higher control.
Hybrid Cloud – Combines public and private models.
Service models include:
| Model | Description | Example |
|---|---|---|
| IaaS (Infrastructure as a Service) | Virtual machines, storage, networking | AWS EC2, Azure VMs |
| PaaS (Platform as a Service) | Tools for developers to build apps | Google App Engine |
| SaaS (Software as a Service) | Software hosted on the cloud | Gmail, Office 365 |
