Enhancement of Data Security in Cloud Computing Environment.

      Аннотация: Cloud computing, a rapidly developing information technology, has aroused the concern of the whole world. It is Internet-based computing, whereby shared resources, software and information are provided to computers and devices on-demand like the electricity grid. To address this longstanding limitation we have developed a multitenant system. This system provides powerful computing capability through a large number of relatively low-cost computing entity and using the advanced business model like SaaS (Software as a Service) to distribute the powerful computing capacity to end users hands.Our system provides the environment for the user to use the software via the URL and again the importance is about to secure users data in cloud.After successful registration, the tenant of SaaS will use his account from any where and with any device but only through allocated URL. Number of tenants use same software simultaneously to maintain their current activity and their account safely. This issue addressed by this system. There is no possibility with this system to conflict tenants’ database.
