Cloud computing service means storing, accessing data and programs over the Internet instead of your computer’s hard drive. The cloud is just a metaphor for the Internet. The clouds changed the market. Any startup can now use resources, which were previously only available to large enterprises.
A client pays only for resources when using any of these cloud models. He/she chooses from the package of services only what is needed specifically for them. Such point-wise use of IT services became possible thanks to cloud technologies.
