What is Cloud Computing?
Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics, and artificial intelligence over the internet.
Rather than maintaining expensive on-premise infrastructure, businesses can provision cloud resources on demand, allowing them to scale quickly while reducing operational complexity.
How Does Cloud Computing Work?
- Applications and data are hosted on cloud infrastructure.
- Users securely access services over the internet.
- Cloud providers automatically manage servers, networking, and storage.
- Resources scale dynamically based on demand.
- Organizations pay only for the resources they consume.
