What is Cloud?
Cloud is not a specific technology or product, it is a concept and an approach. The cloud originally was the symbol for the internet, where specific routes and locations are irrelevant, as long as they were connected. Saying something was in the cloud was another way of saying it’s on the internet for example websites located in a third party’s premises, are accessed and administered over the internet-cloud.
Today, cloud is used to describe a growing number of new inter-related internet technologies and services, such as: online data-storage, web applications – SaaS(Software as a Service), ‘virtualisation’ of physical servers IaaS (Infrastructure as a Service) and more. Cloud is also used to describe how remote resources and services are accessed, often meaning any internet connected device with a suitable client installed can access the cloud service or resource.
