Cloud is an on-demand computing resource delivery model via the Internet. Instead of storing data and running programs on a local computer or server, cloud services allow remote access to them.
The cloud can be thought of as a huge data center managed by a service provider. Users can rent the resources they need (storage, computing power, applications) and pay only for actual usage. This eliminates the need to purchase and maintain own hardware.
Examples of popular cloud services: Google Drive for file storage, Amazon Web Services for hosting websites and applications, Microsoft Office 365 for working with documents and email through a browser.
Cloud technologies provide flexibility, scalability, and availability, enabling efficient use of resources and facilitating collaboration. However, it is important to consider security and privacy issues when transferring data to the cloud.
