Cos’è il Cloud Computing?

Da Wikipedia (http://it.wikipedia.org/wiki/Cloud_computing)

«In informatica con il termine inglese cloud computing (in italiano nuvola informatica) si indica un paradigma di erogazione di risorse informatiche, come l'archiviazione, l'elaborazione o la trasmissione di dati, caratterizzato dalla disponibilità on demand attraverso Internet a partire da un insieme di risorse preesistenti e configurabili.»

La definizione di Cloud Computing del NIST

«Cloud computing is a model for enabling ubiquitous, 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.»

http://www.eurocloud.it/images/nist-originale.pdfhttp://www.eurocloud.it/images/nist-traduzione.pdf

La definizione di Cloud Computing del NIST

«Questo modello cloud è composto da cinque caratteristiche essenziali, tre modalità di servizio e quattro modelli di distribuzione.»

Perché il Cloud?• Creare rapidamente ambienti per guidare le priorità di

business• Scalare per soddisfare le richieste di picco• Aumentare le attività quotidiane, l’efficienza e la riduzione

dei costiEconomicsScaleSpeed

Microsoft Azure

Microsoft Azure
