Why the Cloud matters Huge cost savingsEasier maintenanceIncreased reliability and back-up (if done right!)More rapid developmentSurge capacityCollaboration and mash-ups
What Could Slow It Down Proprietary approaches that aren’t interoperable.Open vs. closed Clouds IT staff and inflexible management mindsets One-to-one policies applied to many-to-many medium:–––––––––Privacy and SecurityAccess to and price of ubiquitous networkingLiabilityProtectionismIntellectual property protectionWiretappingConsumer protectionCompetition policyGovernment procurement
Bottom line With the Cloud, we face many familiar policychallenges,– But they are at least twice as difficult– And at least five times more important
