Ontology of Cloud Computing Service, Technology, and Security

In the electricity speed of the modern technological world, the cloud computing is necessary to save the cost for the economy of the society and save the valuable time and space at home and office. Cloud computing is an accumulation of the extant facility and technology, covered with in an advanced  framework paradigm that offers enhanced scalability, elasticity, business brisk, faster start up time, reduced management cost, and just-in-time availability of resources.  The cloud computing provide many number of services. The services are broadly classified as IAAS, PAAS, and SAAS. The main functionality and partial part of delivery service model to the user through the cloud computing is storing, accessing, retrieving, updating, and sharing the data flexible, scalable, and securable. This paper mainly concentrates on the security of the cloud data. It can share the data in the permanent cost of local resources and the changeable cost of cloud resources without loss or leakage of the data. In anywhere monitoring, maintaining, and managing our data requires confidentiality, integrity, and authenticity. So the cloud mostly uses the cryptographic technique to secure the data. (In the partial part of main functionality of cloud computing the cloud data sharing process part is major). In this case of sharing the data in the cloud transaction, the security is most important for the valuable personal information.
