摘要：The convention of cloud computing has increased promptly in the society. Cloud computing have many benefits in terms of accessibility of data and low expenditure. A fundamental characteristic of the cloud services is that user's data are usually processed remotely in unknown machines that users do not operate. It can be transformed into a momentous roadblock to the wide adoption of cloud services. Make sure that the safety of cloud computing is a main factor in the environment of cloud computing, as users repeatedly store sensitive information with cloud storage providers but these providers may be untrusted. Dealing with "single cloud" providers is expected to become less accepted with customers due to risks of service accessibility collapse and the possibility of malicious insiders in the single cloud. A movement towards "multi- clouds", or in other words, "interclouds" or "cloud- of-clouds" has come into view recently. The emergent popularity of cloud storage space services has show the way companies that handle critical data to think about using these services for their storage space requests. However the trustworthiness and safety measures of data stored in the cloud still remain main concerns. It is found that the research analysis into the use of multi-cloud providers to maintain security has acknowledged less thought from the research community has the use of single clouds. My effort aims to carry the use of multi- clouds due to its capability to decrease security risks that affect the cloud computing user.
