Cloud computing is defined as a model where data and programs are stored on a central server instead of on local devices. This centralization allows for easier access, management, and sharing of resources because users can access their data and applications from any device connected to the internet, rather than being limited to specific local devices. This flexibility supports remote work, collaboration, and scalability, making it a popular choice for businesses and individuals alike.

The architecture of cloud computing simplifies resource allocation and reduces the need for physical hardware maintenance on users' end. Users can benefit from on-demand access to computing power, storage, and applications without needing to invest in their own servers or infrastructure, which is a significant advancement over traditional computing methods where processing and storage were confined to personal devices or local servers.
