Provided are a smart card service method and an apparatus for performing the same. The smart card service method includes receiving a certificate generation request from a terminal, transmitting the certificate generation request to an authentication processing device, and storing credential information with respect to the generated certificate in a virtual machine associated with the terminal in response to a certificate generation success message provided from the authentication processing device. Thus, it is possible to reduce costs in accordance with manufacturing smart card hardware, and support smart card services in a more enhanced security environment.

Disclosed is a dynamic load balancing system. The dynamic load balancing system includes a resource management master managing bare servers that do not execute services and having a hierarchical structure and a service master dynamically allocating the bare servers to a load balancing server or a service execution server or dynamically releasing the pre-allocated load balancing server or service execution server by the bare servers, in consideration of monitoring information on a state or performance of a server and service requirements to be provided.

Dynamic load balancing system and method thereof

Provided are a method and apparatus for obtaining a minimum cost vector for making a skyline object in a multi-dimensional space. The method includes calculating respective vector values having a query point and respective moving points to which the query point is moved as both end points in a multi-dimensional space having a plurality of coordinate axes, and selecting a vector value whose moving point is included in a skyline and has the minimum distance value from the query point as the minimum vector value from among the vector values.
