Cloud computing, or computing in the cloud, has emerged as a new model of computing consumption. IT infrastructure and solutions are made available as on-demand services generally available on the Internet. A confusion remains, which associates the ‘cloud’ not with the provision of the infrastructure, but with the mode of consumption of the services via the Internet and mobile.
What Does Cloud Computing Mean?
Originally, the term ‘cloud computing’ was created to represent a set of heterogeneous and geographically dispersed computing equipment, with their underlying infrastructure (networks), and grouped together in a single, transparent vision, the cloud.
Today, behind the expression ‘cloud computing’ we find several modes of expression of computing. The simplest is the transparent provision of servers, computing and storage, and applications via a network, usually the Internet. The main difference compared to traditional computing, is the provision on demand of a computer sized according to need, consumed and billed for use, without the user having to worry about infrastructure.
By extrapolation, the ‘cloud’ is often proposed and seen from the user’s side as a solution (ERP or CRM for example), an application (mobile apps), or simply a service (web access, commercial page, email ), which runs on his PC or smartphone without him having to know how it works.
Note that in general the infrastructure that supports these services, scalability (sizing according to needs), maintenance, deployment of solutions, support, updates, security, is provided by the cloud provider. Who can be the company in the context of a ‘private cloud’, but the user does not see it!
The Principles Of The Cloud
Cloud computing is based on several principles, which fade with the maturity of companies in the cloud because today they are prerequisites:
On-demand resources and automation of access.
Pooling, allocating resources among multiple users to optimize hardware investments, consumption, and reduce costs. The payment for use, the actual consumption of resources, which can be measured to the nearest possible in extreme cases. The accessibility of services in the cloud on the Internet and via mobile.
