    摘要: Disclosed herein are an apparatus and method for enabling clients to participate in data storage in a distributed file system. The client device of a distributed file system according to the present invention includes a storage determination unit and a file reading unit. The storage determination unit determines whether first metadata information, including a global generation number of the chunk corresponding to a file to be read, has already been stored in the local storage. The file reading unit performs a read operation on the file using local data corresponding to the first metadata information if, as a result of the determination, it is determined that the first metadata information has already been stored.

    摘要: Disclosed herein is an apparatus for controlling sensor data in a cloud system. The apparatus includes a plurality of virtual machines, and a service module. Each of the plurality of virtual machines obtains sensor information about a user terminal by driving an internal sensor data processing module at a request of the corresponding user terminal, and provides the application execution environment of a requested service by connecting to the user terminal over a network. The service module provides an application corresponding to the requested service to a virtual machine which requested the service. When a sensor Application Programming Interface (API) of the user terminal is called by the application, the virtual machine requests sensor data from the user terminal based on the sensor information about the user terminal, and provides the result of measurement of the sensor data from the user terminal to the corresponding application.

    摘要: Provided is an availability prediction method for a high availability. The method includes calculating a basic survival probability that the other node survives until a failure on one node of two nodes constituting a cluster is fixed, and determining an optimal number of nodes meeting a preset reference availability probability by calculating an availability probability for a predetermined range of the number of nodes on the basis of the basic survival probability. The method determines the number of nodes in the high availability cluster so as to match a reference availability probability, and is able to accomplish an optimal configuration of a cluster by calculating the availability probabilities for combinations between active node and passive nodes and between head nodes and switches.
