SSM: Secure Storage Migration among Cloud Providers

Abstract

As Cloud Computing industry is advancing toward an era where resources are delivered as a service rather than a product. It provides infrastructure, software, application, platform, data and resources as a service over the internet with on-demand and pay-per-use model. Clouds are used for hosting a large range of services. These services between different Cloud Service Providers, has different pricing model and the cost of individual resources are very different. Heterogeneity among different Cloud providers causes many problems like vendor lock-in. In order to decrease the dependency and minimize the cost of running a service, it becomes mandatory to move the data between different Clouds. The focus of this paper is to solve portability conflict in IaaS(Storage) offerings. Results demonstrate in the paper shows how portability can be achieved using virtual appliances. Our efforts also focus on the security of storage data migration between different clouds. The solution to secure storage migration between clouds mainly involves in Secure Socket Layer Negotiations, exchanging temporary keys, tokens and blocks encryption in distributed file systems.
