Abstract: There is provided a cloud management method and apparatus for performing load balancing so as to make a service in a cluster that is geographically close in an associative container environment and has a good resource current status. The cloud management method according to an embodiment includes: monitoring, by a cloud management apparatus, available resource current statuses of a plurality of clusters, and selecting a cluster that owns a first service supported by a first cluster an available resource rate of which is less than a threshold value; calculating, by the cloud management apparatus, scores regarding an available resource current status and geographical proximity of each cluster; and performing, by the cloud management apparatus, load balancing of the first service, based on a result of calculating the scores. Accordingly, a delay in a response speed of a service that is required in a distributed environment can be minimized, and a service can be supported to be processed in a geographically close cluster through analysis of geographical closeness (proximity) between an access location where there is a user request and a cluster in which services are distributed.

Abstract: A method for producing a support structure of a 3D model for 3D printing is provided. A method for producing a support according to an embodiment of the present invention comprises the steps of: dividing a surface constituting a 3D model into multiple surface patches; classifying respective divided surface patches according to geometric characteristics; and producing supports corresponding to the classified characteristics with regard to respective surface patches. Accordingly, during metal laminate manufacturing, the output stability may be improved while reducing the support producing process time. In addition, the surfaces may be expressed by different colors according to the result of geometric characteristic classification, and the supports may also be expressed by different colors according to the type, thereby playing the role of guide lines such that the user can recognize the shape of the surfaces and the type of supports to be installed on the corresponding surfaces. Moreover, the size of a support tip is determined in view of the thickness of the area in which a support is to be produced, thereby preventing the problem of output quality degradation which would otherwise occur because the support cannot move upwards through an output part.
