Cloud computing is the delivery of computing services—like storage, servers, databases, and software—over the internet.
Instead of owning physical hardware, users access resources on demand from cloud providers.
Cloud computing offers scalability, letting businesses increase or decrease resources as needed.
It provides high availability and reliability, with minimal downtime.
Major service models include IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).
Deployment models include Public, Private, Hybrid, and Community clouds.
Cloud enhances collaboration by allowing multiple users to work on the same system from anywhere
Security, privacy, and internet dependency are key challenges in cloud computing.
