Cloud computing

Cloud computing is a technology paradigm that involves delivering various computing services, including storage, processing power, networking, databases, analytics, software, and more, over the internet rather than relying on a local server or a personal computer's hard drive. Cloud computing provides on-demand access to a shared pool of computing resources, allowing users to access and use services without having to invest in or manage their own infrastructure.

Key characteristics of cloud computing include:

On-Demand Self-Service:
Users can provision and manage computing resources as needed, without requiring human intervention from the service provider.

Broad Network Access:
Cloud services are accessible over the internet from a variety of devices, such as laptops, smartphones, and tablets.

Resource Pooling:
Computing resources, such as processing power, storage, and bandwidth, are pooled and shared among multiple users. Resources are dynamically allocated based on demand.

Rapid Elasticity:
Cloud resources can be quickly scaled up or down to accommodate changes in demand. This enables users to only pay for the resources they consume.

Measured Service:
Cloud computing resources are metered, and users are billed based on their usage. This pay-as-you-go model provides cost efficiency and flexibility.
