What is Cloud?
Cloud computing, or simply Cloud, is the "delivery of computing" as a service rather than a product, where shared resources, software and information are provided, allowing access via any computer, tablet or cell phone connected to the Internet.
In this concept, unlike other services such as dedicated servers, the Cloud has decentralized resources, i.e. there are machines responsible only for processing, machines responsible only for allocating memory and machines responsible only for storage.
In this way, the degree of reliability is very high and scalability is flexible: during working hours your cloud has maximum resources and during the night, when there are no working hours, it is reduced to a minimum.
That's just some of the Cloud's capacity!
