Gestione in modalità Adaptive:

§ virtualizzazione della potenza di calcolo erogata

§ scompare la necessità di dimensionare in funzione dei picchi di carico o di prevedere le future crescite

§ gli ambienti hanno sempre la corretta quantità di risorse disponibili

§ la gestione e quindi i costi sono proporzionali alle risorse effettivamente utilizzate

§ la disponibilità on-line delle Applicazioni del Cliente è assicurata dall’elevato livello di resilienza Servizi
