A Survey on Data Security Issues in Cloud Computing: From Single to Multi-Clouds

TLDR

Cloud computing has rapidly expanded, offering low cost and accessibility, but raises significant security concerns about data integrity, availability, and insider threats, prompting a shift toward multi‑cloud architectures. This survey aims to review recent research on single and multi‑cloud security and advocate multi‑cloud adoption to mitigate consumer risks. The authors conducted a comprehensive literature review of studies on single and multi‑cloud security, synthesizing findings and proposing potential solutions. They found that research on multi‑cloud security is considerably less explored than single‑cloud security.

Abstract

Cloud computing usage has increased rapidly in many companies. Cloud computing offers many benefits in terms of low cost and accessibility of data. Ensuring the security of computing plays a major role in the computing, as customers often store important information with storage providers but these providers may be unsafe. Customers are wondering about attacks on the integrity and the availability of their data in the from malicious insiders and outsiders, and from any collateral damage of services. These issues are extremely significant but there is still much room for security research in computing. Dealing with cloud providers is predicted to become less popular with customers due to risks of service availability failure 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 increased recently. The purpose of this paper is to survey recent research related to single and multi-clouds security and to address possible solutions. It is found that the research into the use of multi-cloud providers to maintain security has received less attention from the research community than has the use of single clouds. This work aspires to promote the use of multi-clouds due to its ability to reduce security risks that affect the computing consumer.
