Many companies are moving to the cloud, but they are still concerned about security issues regarding how they dat is segregated , how is privacy preserved, how can they move their data back to their systems if needed. Cloud-based services are still very immature and it is very risky to rely on a single cloud service provider. In summary it is apparently compelling that the cloud computing industry forums need to define  the standards and procedures for security, privacy, data moving and service recovery, in  order to boost the public confidence on the cloud. Without necessary regulatory and industry  standards, the acceptance of cloud based services, would be still "cloudy".
