A Study of Cost Optimization of Cloud Data Storage

Cloud becomes more attractive and easy to use for everyone and people are more familiar with provided services and environments. One of the main aims of large-scale distributed systems such as the Cloud is to solve the problem of storage, data availability, and especially their security in public and shared environments where providers impose costs for end-users. In this paper we propose a cost minimization model based of Cloud Data Storage. The main scope is to find a cost efficient storage scheme for many heterogeneous data blocks using multiple public Cloud storage providers. The proposed model is validated through simulation using a realistic scenario: CyberWater -cyber infrastructure for natural resource management.
