Cloud infrastructure a key investment today

Trustworthy? Not really.

you’d trust the cloud to store:Data you can lose access to for a whileStuff that is not really private/confidential

but rarelyData you need fast/full/private access to.Important data reside outside the cloud

Common complaintsNot fast, predictable, reliable enoughNo privacy guaranteesWhat if the cloud loses data?Poor application/storage interfaceData is not easily movable
