Abstract :

The end of this decade is marked by a paradigm shift of the industrial information technology towards a pay-per-use service business model known as cloud computing. Cloud Computing is a new environment in computer oriented services. It is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This system have some similarities of distributed system, according to this similarities cloud computing also uses the features of networking. Cloud data storage redefines the security issues targeted on customer�s outsourced data (data that is not stored/retrieved from the costumers own servers). In this work we observed that, from a customer�s point of view, relying upon a solo Server for his outsourced data is not very promising. In addition, providing better privacy as well as ensuring data availability can be achieved by dividing the user�s data block into data pieces and distributing them among the available Servers in such a way that no less than a threshold number of Servers can take part in successful retrieval of the whole data block. If one of the Servers get crashed or is down the data is retrieved from the backup link. In this paper, we propose a secured and trusted multi-cloud storage (STMCS) model in cloud computing which holds an economical distribution of data among the available Servers, to provide customers with data availability as well as secure storage.
