Cloud computing delivers computing services — like servers, storage, databases, networking, software, and analytics — over the internet ("the cloud"). This allows users to access resources on-demand without managing physical hardware. Key Characteristics: On-Demand Self-Service: Resources can be provisioned automatically. Broad Network Access: Services are available over the internet from any device. Resource Pooling: Multiple users share resources dynamically. Rapid Elasticity: Resources scale up or down based on demand. Measured Service: Users pay only for what they use. Service Models: IaaS (Infrastructure as a Service): Virtual machines, storage, and networks (e.g., AWS EC2). PaaS (Platform as a Service): Platforms for app development (e.g., Google App Engine). SaaS (Software as a Service): Software accessed online (e.g., Gmail, Dropbox).and much more
