Question

Accepted Answer

Cloud Computing is a technology that allows people to store, manage, and access data and programs over the internet instead of using their own computer's hard drive, providing services like storage, software, and processing power through online servers. The cloud computing models are: (i) SaaS (Software as a Service) - ready-made software accessed via the internet, e.g., Google Docs, Gmail. (ii) PaaS (Platform as a Service) - a platform for developers to build and deploy apps, e.g., Google App Engine, Firebase. (iii) IaaS (Infrastructure as a Service) - virtual servers, storage, and networks, e.g., Amazon EC2, Google Compute Engine.
