What is cloud computing?

Cloud computing refers to the delivery of computing services over the internet, allowing users to access and utilize resources such as servers, storage, databases, networking, software, and more, without the need for local infrastructure or hardware. In simpler terms, it enables individuals and organizations to use Cloud Computing Training in Noida resources on-demand, paying only for what they consume, much like electricity or water utilities.
In a cloud computing model, these services are typically categorized into three main types:
Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet, including virtual machines, storage, and networking. Users can deploy and manage their own operating systems, applications, and software on these virtualized resources.
Platform as a Service (PaaS): Offers a platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure. PaaS provides tools, development frameworks, and middleware to streamline the development process.
Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis. Users can access these applications through a web browser without needing to install or maintain them locally. Common examples include email services, office productivity suites, and customer relationship management (CRM) software.
Cloud computing offers several benefits, including scalability, flexibility, cost-effectiveness, and accessibility from anywhere with an internet connection. It has become an integral part of modern IT infrastructure, powering everything from web hosting and data storage to artificial intelligence and big data analytics.
