Cloud computing is a model for delivering services like servers, storage, databases, and software over the internet. Instead of maintaining physical hardware, you rent access from a cloud provider and pay only for what you use. This makes it a flexible and cost-effective option for businesses of all sizes.
The following are the core characteristics that define cloud computing as a service model:
- On-demand access: Access resources as you need them — no upfront infrastructure investment required
- Scalability and elasticity: Scale your resources up or down easily to match customer demand
- Pay-as-you-go pricing: Pay only for the computing resources you actually consume
- Global accessibility: Access your services and data from any location with a stable internet connection
- Managed infrastructure: The provider handles maintenance and hardware so you can focus on building your applications
