Carrying abstraction to its conclusion

Abstracting data from the physical disksupon which it residesAbstracting network connectivity to

simplify data center interconnects

Abstract applications from the OSand enable JeOS (“Just enough OS”)

Abstracting data access from data location

Enabling the vision of the private cloud
