Cloud storage service is currently becoming a very popular solution for medium-sized and startup companies. However, there is still no suitable solution being offered to deploy transactional databases in a cloud platform. The maintenance of ACID (Atomicity, Consistency, Isolation and Durability) properties is the primary obstacle to the implementation of transactional cloud databases. The main features of cloud computing: scalability, availability and reliability are achieved by sacrificing consistency. While different forms of consistent states have been introduced, they do not address the needs of many database applications. In this paper we present a tree-based consistency approach, called TBC, that reduces interdependency among replica servers to minimize response time of cloud databases and to maximize the performance of those applications. Experimental results indicate that our TBC approach trades off availability and consistency with performance.
