Cloud computing allows you to access software and data remotely, without relying on physical storage devices or on-premises servers. Here are some key concepts to understand about cloud computing:

• Without the use of physical storage devices, you may remotely store and retrieve files and data thanks to cloud storage. The quantity of storage you utilize is usually reflected in the monthly rate charged by cloud storage providers.
• Applications in the cloud are those that may be accessed online rather than being downloaded to a computer or mobile device. Salesforce, Microsoft Office 365, and Google Docs are a few examples of cloud applications.
• Infrastructure as a Service (IaaS): IaaS offers virtualized computer resources over the internet, including servers, storage, and networking. Customers do not need to invest in their own physical infrastructure because they can rent these resources on a pay-as-you-go basis.
• Software as a platform Platform as a Service (PaaS): PaaS offers a platform for creating, testing, and deploying software applications. PaaS vendors generally provide predefined development environments, tools, and services to aid in the speedy and effective creation and deployment of applications.
