[ahmed dohar]

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

[Mohamed El-Refaey]

You can also think of cloud computing as a way to offload the management and maintenance of your infrastructure to vendors who take care of this and you focus more on your own core business

You can also think of cloud as public utility as water, electricity, in which you pay only for your usage and when you release these services, you won't need to pay any.
