- Cloud Computing: The delivery of computing services—servers, storage, databases, networking, software, analytics, and more—over the internet (“the cloud”).
- On-Demand Access: Users can access services anytime without needing to manage physical infrastructure.
- Pay-As-You-Go: You only pay for the resources you use, making it cost-effective and scalable.
📌 Key Characteristics
- Scalability: Easily scale resources up or down as needed.
- Elasticity: Automatically adjust resources to match demand.
- High Availability: Services are available globally with minimal downtime.
- Global Reach: Services can be delivered from data centers around the world.
🏢 Traditional vs. Cloud
- Traditional IT: Requires purchasing and maintaining physical servers and infrastructure.
- Cloud Computing: Offers flexibility, cost savings, and access to advanced technologies without upfront capital costs.
💡 Summary
- Cloud computing delivers IT services over the internet.
- It provides on-demand access, scalability, and cost-efficiency.
- It differs significantly from traditional on-premises IT models.
