Cloud computing is a construction for providing computing services via the internet on demand and pay 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, such as banking, healthcare and education 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 a completely internet dependent technology where client data is stored and maintain in the data centre of a cloud provider like Google, Amazon, Salesforce.com and Microsoft etc. Limited control over the data may incur various security issues and threats which include data leakage, insecure interface, sharing of resources, data availability and inside attacks. There are various research challenges also there for adopting cloud computing such as well managed service level agreement (SLA), privacy, interoperability and reliability. This research paper outlines what cloud computing is, cloud architecture, the various cloud models, the main security risks and issues that are currently present within the cloud computing trade. This research also include the discussion about the best practices to service providers as well as enterprises hoping to leverage cloud service to improve their bottom line in this severe economic climate.
