The security issues and solutions related to cloud computing are a strongly debated academic topic at the moment. Even though there have been many studies on cloud security, there is still some uncertainty about how to link issues with solutions. It is challenging to both generalize the idea and investigate its particular needs since there is no established framework for cloud security. Some polls focus on access control systems, while others discuss virtualization issues and solutions. A survey's suggested countermeasures must also specifically state the issue they are meant to solve. All of these factors have been taken into account while writing this survey paper, which includes a discussion of many open questions in the subject and covers all pertinent themes with appropriate links between them.
