¿ES CLOUD?
Desde el punto de vista técnico, dentro de la variante de Infraestructura como Servicio (IaaS), el término Cloud está asociado con la virtualización, que permite múltiples aplicaciones por cada nodo informático, cuando en el modelo tradicional sólo permitía una aplicación por cada nodo informático físico.
Descrito de un modo más técnico, el lugar que antes ocupaba el sistema operativo en un nodo físico, pasa a ser ocupado ahora por lo que llamamos hipervisores, unos sistemas que permiten instalar sobre ellos tantos sistemas operativos independientes como queramos dentro de un mismo nodo físico.
