A Research on Various Security Aware Mechanisms in Multi-Cloud Environment for Improving Data Security

The idea of multi-cloud computing has broadened the field of cloud computing and has emerged as a popular term currently. The term "multi-cloud" refers to the use of services from numerous heterogeneous cloud service providers through a common framework at the user’s (e.g., organizations or firms) facilities. Cloud computing is faced with several issues and research gaps, prompting academic and commercial work to pave the way for a multi-cloud system. The concept of multi-cloud is growing, and various research efforts are currently ongoing to create a multi-cloud framework that is supported in all aspects such as easy configuration, security, management, etc. In this study, the main ideas, difficulties, requirements, and future perspectives for multi-cloud environments are discussed briefly. Moreover, a study of conventional methods and solutions given by various multi-cloud frameworks are analyzed, along with their benefits and downsides are also discussed.
