Design and Implementation of Single to Multi-cloud Securities in Network

The adoption of cloud computing has skyrocketed in a lot of companies. One of the biggest selling points of cloud computing is how cheap it is and how easily you can access your data. Since users routinely save sensitive data with cloud storage providers despite the fact that they may not be reliable, cloud computing security is a vital concern in the cloud computing ecosystem. Due to concerns around current service failure and damaging entrants in the single-cloud, consumers are predicted to shift away from engaging with “single cloud” suppliers. Multiple clouds, or “inter-clouds” as they are sometimes called, are becoming increasingly popular. In this study, we investigate the problem of securing multiple cloud environments and discuss some potential approaches to the problem. Researchers have paid less effort to studying how to use several cloud providers while keeping data secure than they have to studying individual clouds. Multi-clouds can reduce vulnerability to some types of attacks, hence this initiative aims to increase their adoption. However, there are still major worries about the security and trustworthiness of cloud-based data storage. We present DEPSKY, a system that encrypts, encodes, and replicates data over numerous clouds to increase availability, integrity, and confidentially stored in the cloud. Our infrastructure, together with Planet Lab, has been deployed to four commercial clouds, where users from all around the world can use the service. Our protocols improved perceived availability and, for most cases, access latency when compared to those of individual cloud providers.
