Abstract

Cloud Computing is an environment for providing information and resources that are delivered as a service to end-users over the Internet on demand. Thus cloud enables users to access their data from any geographical locations at any time and also has brought benefits in the form of online storage services. Cloud storage service avoids the cost expensive on software, personnel maintenance and provides better performance, less storage cost and scalability. But the maintenance of stored data in a secure manner is not an easy task in cloud environment and especially that stored data may not be completely trustworthy. Cloud delivers services through internet which increases their exposure to storage security vulnerabilities. However security is one of the major drawbacks that preventing several large organizations to enter into cloud computing environment. This work surveyed on several existing cloud storage frameworks, techniques and their advantages, drawbacks and also discusses the challenges that are required to implement secure cloud data storage. This survey results help to identify the future research areas and methods for improving the existing drawbacks.
Keywords: Cloud Computing, Data, Security, Storage Techniques and Survey.
