1. Getting consumer-grade Software as a Service right is a challenge
2. Moving data from traditional data stores to the cloud is difficult and error-prone
3. Data privacy/protection is still an issue with cloud services (also refer Facebook privacy nightmares)
Restoring consumer confidence is not a perfect science; AWS customers seemed happy with a public post from the company detailing the reasons (technical and infrastructural) for the outage they experienced about 6 months ago. The past week has not been good for consumer-centric cloud services, what with the Blackberry outage and the iCloud issues. Both these companies can restore consumer confidence by explaining what went wrong and the adjustments made to provide virtually uninterrupted service in the future.
