Abstract:   Cloud computing is a model which provides convenient, ubiquitous, on-demand network access to a shared pool of configurable computing resources that can be processed immediately and released with minimal management effort or service provider interaction. Since cloud computing has many features like increased efficiency, flexibility, disaster recovery and security many businesses are moving to cloud computing. The advent of proposed model has capabilities to ensure maximum performance of features like data locks, fault tolerance and disaster recovery. Data lock-in has potential to obstruct portability and interoperability however the proposed model has tools and techniques to manage data in cloud that keeps it accessible and portable to ensure cross-provider compatibility. The existing cloud computing systems are prone to failure which can be then dealt with fault tolerance feature that assesses the ability of a system to respond gracefully to an unexpected hardware or software failure. The proposed solution helps to achieve robustness and dependability in cloud computing by handling failure effectively. Cloud disaster recovery is a backup and restores strategy that involves storing and maintaining records in a cloud computing environment as a security measure. The proposed framework provides an organization with a way to recover data and implement failover in the event of a man-made or natural catastrophe.
