Cloud computing is a model for delivering information technology services in which resources are retrieved from the internet through web-based tools and applications, instead of a direct connection to a server. It involves the use of remote servers on the internet to store, manage, and process data, instead of a local server or a personal computer.
Some common modern-day uses of cloud computing include:
Software as a Service (SaaS): This includes popular applications like email, customer relationship management (CRM), and enterprise resource planning (ERP) systems, which are delivered to users over the internet.
Infrastructure as a Service (IaaS): This involves the use of virtualized computing resources, such as virtual machines, storage, and networking, which can be purchased and scaled as needed.
