The proposed work studies hosting types and aims to promote the use of single and multi-clouds to reduce the risks. Cloud computing is a multi-paradigm technology which has evolved as a cost effective, flexible, performance oriented infrastructure for agile development of business operations. Cloud computing changes the way we think about computing by decoupling data processing, data retention, and data presentation – in effect, divorcing components from location. Today due to the need of hour and security constraints, single cloud computing is transforming to multi cloud computing. Focus has been done on Multi cloud which is also known as " inter cloud " or " cloud of clouds " which reduces the security risks like failure of service availability, data loss and confidentiality breaches that are drawbacks with single cloud.
