 What is Cloud Computing? 

Cloud computing is a model of computing that delivers computing resources over the internet. It allows users to access and use shared computing resources, such as applications, data, and storage, rather than having to build and maintain their own infrastructure. This enables organizations to focus on their core business, rather than the underlying hardware and software infrastructure.

 Cloud computing can be classified into three categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).

1. Infrastructure as a service (IaaS) is a cloud computing model in which a third-party provider delivers infrastructure resources, such as virtual machines (VMs), storage, and networking, over the internet. Users can access these resources as needed and only pay for the resources they consume.

2. Platform as a service (PaaS) is a cloud computing model in which a third-party provider delivers a platform for developers to build and run applications. The platform typically includes an operating system, development tools, and a runtime environment, and users only pay for the resources they consume.

3. Software as a service (SaaS) is a cloud computing model in which a third-party provider delivers software applications over the internet. Users can access and use the software through a web browser, and only pay for the resources they consume.
