Today’s most modern research area of computing is cloud computing due to its ability to diminish the costsassociated with virtualization, high availability, dynamic resource pools and increases the efficiency ofcomputing. But still it contains some drawbacks such as privacy, security, etc. This paper is thoroughlyfocused on the security of data of multi tenant model obtains from the virtualization feature of cloudcomputing. We use AES-128 bit algorithm and cloud SQL to protect sensitive data before storing in thecloud. When the authorized customer arises for usage of data, then data firstly decrypted after thatprovides to the customer. Multi tenant infrastructure is supported by Google, which prefers pushing ofcontents in short iteration cycle. As the customer is distributed and their demands can arise anywhere,anytime so data can’t store at particular site it must be available different sites also. For this fasteraccessing by different users from different places Google is the best one. To get high reliability andavailability data is stored in encrypted before storing in database and updated every time after usage. It isvery easy to use without requiring any software. This authenticate user can recover their encrypted anddecrypted data, afford efficient and data storage security in the cloud.
