Cloud Computing: Security Issues

Cloud computing is an architecture which provides computing service through the internet on demand and pays per use access to a pool of shared resources namely networks, storage, servers, services and applications, without physically acquiring them. So it saves managing cost and time for organizations. Many industries are moving towards the cloud due to the efficiency of services provided by the pay-per-use pattern based on the resources such as processing power used, transactions carried out, bandwidth consumed, data transferred, or storage space occupied, etc. Cloud computing is an internet dependent technology where client data is stored and maintained in the data center of a cloud. Example Google, Amazon, Salesforce.som and Microsoft, etc. Limited control over the data may occur various security issues and threats which include data leakage, insecure interface, sharing of resources, data availability and inside attacks. Various research also challenges there for adopting cloud computing such as well managed service level agreement (SLA), privacy, interoperability and reliability. This research paper describes the security issues of cloud computing
