A Multi-Cloud based Approach to Enhance Data Security and Availability in Cloud Storage

Cloud computing is growing at a rapid pace, because of its promising low investment practices and the ease of access to data and services. But the security of sensitive data is an open challenge in untrusted cloud environments. Due to the single point failure model, single clouds possess the risk of service unavailability. The possibility of insider attacks in single clouds is also worrying cloud investors. As a remedy, movement towards multi-cloud environments is emerging. This paper focuses on recent research related to cloud security and highlights the advantages of high security and high data availability that is found using the multi-clouds. This paper proposes a new way of handling the cloud storage which is fairly simple to manage and also is robust to most of the data attacks that usually occur in the present cloud storage scenario. This paper explained the added advantage of using the existing infrastructure in a far effective way than that is being done now. This paper aims at relieving the end users of any concerns about the safety of the data being stored in the cloud storage and the availability of the services.
