Data Security ,Isolated access to data in Cloud : A Review

computer science engineering

Cloud Computing is one of the popular techniques due to its ability to minimize the cost of computing when scalability and flexibility of computer process get increased. Cloud Computing provides shared resources and services via internet. Services are delivered through data center. Cloud Computing allows an interesting business proposal for IT industries to provide IT services without any extra investment. Client is able to perform heavy computer processes with low capable device (like mobile) which has resource to run the web browser. But cloud computing is crowded with many security related issues. When client saves his data to the company’s cloud, there may be chance of data breaching. As information exchange plays an important role in today’s life, information security becomes more important. This paper is focused on the security issues of cloud computing and techniques to overcome the data privacy issue. Before analyzing the security issues, the definition of cloud computing and brief discussion to under cloud computing is presented, then it explores the cloud security issues and problem faced by cloud service provider.So the purpose of this paper is to search out various issues in cloud computing where all computing is done on the server side and both data & tasks are stored on the data centers. It is very difficult for the customers to switch from one Cloud Service Provider (CSP) to another. It results in dependency on a particular CSP for service.This risk involves the failure of isolation mechanism that separates storage, memory, routing between the different tenants.
