Cloud users remain worried by security

Firms that have switched to cloud computing continue to worry about security, vendor lock-in and management, according to analysts.

However, those using the cloud and those who after all haven't moved to the computing model have different concerns, according to an IDC survey of 700 IT decision-makers.

"In the medium term, IDC believes public cloud vendors will all have to address these and other governance issues, as they will assist them to retain clients and win over those who are unwilling to place business-critical processes in the cloud."
