Cloud

In computer science, "Cloud" refers to a model of computing that enables on-demand access to a shared pool of configurable computing resources (such as networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing allows users to access and use technology services over the internet (the "cloud") rather than having local servers or personal devices handle applications and data management.Cloud services are typically categorized into three main types:1. **Infrastructure as a Service (IaaS)** - provides virtualized computing resources over the internet. 2. **Platform as a Service (PaaS)** - offers hardware and software tools over the internet, typically for application development. 3. **Software as a Service (SaaS)** - delivers software applications over the internet, on a subscription basis, eliminating the need for installation and maintenance by users.The cloud model promotes flexibility, scalability, and cost efficiency, enabling businesses and individuals to use computing resources as needed, without the burden of extensive infrastructure management.
