Cloud computing is a model for delivering information technology services in which resources, such as servers, storage, databases, networking, software, analytics, and intelligence, are provided over the internet as a utility, on-demand, and on a pay-as-you-go basis.
It allows users to access, store, and manage data and applications remotely, without the need for local servers or infrastructure. This enables organizations to focus on their core business activities and outsource the management of their IT resources to third-party providers.
Cloud computing services are typically grouped into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS providers offer virtualized computing resources, including servers, storage, and networking, while PaaS providers offer a platform for developing, testing, and deploying software applications. SaaS providers offer software applications, such as email, customer relationship management, and enterprise resource planning, that can be accessed over the internet.
This technology allows users to take advantage of the scalability, reliability, and cost-efficiency of shared resources and enables them to operate more flexibly and efficiently.
