Even though the advantages of usage the cloud seems to be attractive, the enterprise decision-makers should also consider the security threats associated with cloud-service migration, thereafter have to take necessary precautions to overcome or to eliminate those security issues and perform a threat free cloud migration to ensure data confidentiality and completeness on the new Virtual Environment.
