The aspects of consistency management of highly-distributed transactional database in a hybrid cloud environment for the energy sector

摘要

For many years, there are tendencies to support collaborative work of companies of the energy sector, but only the arrival of cloud computing open the door for the implementation of these ideas and aspirations. This actually means a transition to advanced business model and platform with possibilities for launching energy efficient convergent services. From currently available cloud deployment models, as adequate for the energy sector will be considered a hybrid model, as a very efficient, flexible and comprehensive solution. Immediately after the establishment of a common cloud environment the focus of research redirects to the crucial problem of the organization and management of this complex, highly-distributed environment? Especially regarding transactional cloud database and maintaining its consistency. So far, there have been applied conventional methods for preserving consistency and the other ACID rules in highly-distributed transactional environments. However, the actual goal is to make a step forward and to find the optimal solution for preserving the consistency of the entire cloud DBMS. Therefore, this paper discusses adaptable and dynamic approach to preserving consistency of transactional cloud database called TBC (Tree-Based Consistency) approach. It will be shown that this approach provides optimal results and the expected performance of the entire cloud environment.
