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
