    摘要: A method for balancing database workloads among a plurality of database servers includes when a new server is available, selecting a set of master and slave databases to be migrated to the new server; and migrating the selected databases to result in a balanced new workload among all servers while minimizing migration cost; and during operation, if workload unbalance is detected in real time from a workload change in a certain database, iteratively selecting one database at a time to migrate to a different server to balance the workload.

    摘要: A system and method are provided for data sharing. A uniform communication framework is provided as part of a sharing service on the cloud platform to facilitate data sharing among a plurality of applications. The uniform communication framework includes an application programming interface which provides a communication gateway to permit a first application to access data of a second application stored in the data store.

    摘要: A computer-implemented method for pairing a new document to a document from a plurality of documents. Embodiments include, for each of the new document and the plurality of documents, generating a vector of terms of interest uniquely associated with a document of the new document and the plurality of documents. For each term of interest, an associated element value of the vector is assigned as zero if the term of interest does not occur in the document and one otherwise. The method also includes, for each document from the plurality of documents, determining a similarity between the vectors. The method also includes selecting a document from the plurality of documents as related to the new document if the similarity between the vector for the new document and the vector for the document from the plurality of documents is greater than or equal to a threshold value.

    摘要: A method and system for forming service compositions to provide service components to business processes. Service components independently needed by each business process are identified. At least one of the service components is needed by at least two business processes. At least two different service components are needed by at least one business process. At least two service compositions are specified. Each service composition includes at least one service component. At least one service composition comprises at least two service components. An optimal subset of the service compositions is ascertained, such that the total cost of deploying the service compositions in the optimal subset to provide the service components independently needed by each business process does not exceed the total cost of deploying the service compositions in any other subset of the service compositions to provide the service components independently needed by each business process.

    摘要: A method for database consolidation includes generating a model for expected penalty estimation; determining a tenant's value as a function of query arrival rate and SLA penalty; placing a tenant to minimize a total expected cost in the order of the tenant value; and progressively using additional servers to prevent any server from being saturated to guarantee a tenant placement that costs no more than four times the cost of any other placement.
