Classification and Live Migration of Data-Intensive Cloud Computing Environment

Cloud computing is an emerging technology providing software and hardware resources to the users’ as pay-per-use basis, on the other hand in surge demand of current needs of anywhere and anytime the concept of mobile computing came into view. Both aims to provide service to the users as per their requirements and cloud computing provide better flexibility in terms of PaaS, SaaS and IaaS. Database handling is the important consideration of above type of computing environments. Many researchers are proposed issues of database using SQL and NoSQL space suitably for cloud computing scenario. Again available classification for the cloud database sited as a structured and unstructured schema-based along with small and big databases concepts. In this paper we have conducted a study of cloud databases as well as its classification in terms of ACID and NoACID. Again our work focuses on the architectural issues on Database as a Service (DaaS) based on the live migration from ACID based Database to NoACID based Database and vice-versa.
