Cloud computing is the on-demand delivery of computing services—including servers, storage, databases, networking, and software—over the internet. Instead of maintaining physical data centers and servers on-premises, businesses and individuals rent access to these resources from cloud providers like AWS, Microsoft Azure, or Google Cloud. Key benefits include cost efficiency, as users typically pay only for the resources they consume; scalability, allowing systems to instantly adjust to workload demands; and accessibility, enabling data and applications to be reached from anywhere with an internet connection. The cloud operates on virtualization technology, pooling physical resources into a logical environment. It is categorized into public, private, and hybrid deployment models, and service types such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). By outsourcing infrastructure management, organizations can focus on innovation and agility rather than hardware maintenance.
