Understanding Cloud Computing
Cloud computing eliminates the need for organizations to own infrastructure and manage data centers on-site. Instead, it shifts IT operations to a utility-based model where resources are provisioned dynamically, scaled elastically, and billed consumption-wise.
Key characteristics that define cloud environments include:
- On-demand self-service provisioning of compute and storage
- Broad network access via standardized protocols
- Resource pooling with multi-tenant architectures
- Rapid elasticity and auto-scaling capabilities
- Measured service with granular usage tracking
