Cloud computing is a modern computing model that delivers on-demand access to computing resources such as servers, storage, databases, networks, software, and analytics over the internet. Instead of owning and maintaining physical infrastructure, organizations can rent these resources from cloud service providers, enabling cost savings, scalability, and flexibility. It operates on three primary service models: Infrastructure as a Service (IaaS), which provides virtualized hardware; Platform as a Service (PaaS), offering development and deployment environments; and Software as a Service (SaaS), delivering ready-to-use applications online. Cloud computing can be deployed in public, private, hybrid, or multi-cloud environments based on organizational needs. Key benefits include reduced IT costs, rapid innovation, global accessibility, disaster recovery, and enhanced collaboration. However, challenges such as data security, compliance, and vendor lock-in remain. Overall, cloud computing has transformed the way businesses and individuals access, manage, and scale digital resources efficiently.
