Each database host in the cloud platform often has to service more than one database application system. However, under the resource limitations of the host, evenly distributed databases into each host is an important issue needed to be addressed. The database sizes and the number of databases must be taken into account for workload balancing among database hosts. If too many data or databases are gathered in only few database hosts, the data skew may occur and result in poor quality of service. Currently, how to evenly allocating databases into hosts has not been concerned yet.
