摘要：C this paper we propose and evaluate The use of cloud computing has increa sed rapidly in many organizations. Cloud computing provides many benefits in terms of low cost and accessibility ofdata. Ensuring the security of cloud computing is a major factor inthe cloud computing environment, asusers often store sensitive information with cloudstorage providers but these providers may beun trusted. Dealing with "single cloud" providers ispredicted to become less popular with customers dueto risks of service availability failure and thepossibility of malicious insiders in the singl e cloud. Amovement towards "multi -clouds", or in other words,"Inter clouds" or "cloud -of-clouds" has emergedrecently.This mainly focuses on the issues related to the data security aspect of cloud computing. As data and information will be shared with a third party, cloud computing users want to avoid a untrusted cloudprovider. Protecting private and important information, such as credit card details or a patient's medical records from attackers or malicious insiders is of critical importance. In addition, the potential for migration from a single cloud to a multi -cloud environment is examined and research related to security issues in single and multi-clouds in cloud Computingis surveyed.
