Abstract:
Disclosed herein is a cloud service broker apparatus and method for providing a cloud service using the broker apparatus, which provide an optimal cloud service for a cloud service user through negotiations between the cloud service user and a cloud service provider. The cloud service broker apparatus includes an operation information management unit for examining a demand entered by a cloud service user. A broker intermediary unit detects a cloud service based on the demand for which verification has been completed by the operation information management unit, and sends a request for positioning of the cloud service for the cloud service user to a cloud service provider that provides the detected cloud service. A life cycle management unit monitors a cloud service positioned in and used by the cloud service user at a request of the broker intermediary unit.
Abstract:
Disclosed herein are a cloud service brokerage method and apparatus using a service image store. The cloud service brokerage apparatus includes a reception unit for receiving service requirements from each of users, a service image recommendation unit for recommending one or more candidate service images that satisfy the requirements among multiple service images stored in a service image store, a cloud server recommendation unit for recommending one or more candidate cloud servers that satisfy the requirements among multiple cloud servers, a registration unit for registering an optimal service image selected by the user from among the one or more candidate service images in an optimal cloud server selected by the user from among the one or more candidate cloud servers, and a transmission unit for transmitting results of a service implemented by executing the optimal service image on the optimal cloud server to the user.
Abstract:
Disclosed herein is an apparatus for supporting automation of configuration management of a virtual machine applicable to a multi-cloud environment. In accordance with an embodiment, the apparatus includes an interface unit for receiving configuration management information or information of a virtual machine to which configuration management is to be applied. A configuration management verification unit verifies the received configuration management information, and combines the virtual machine information with configuration management information corresponding to the virtual machine. A configuration management distribution unit distributes the configuration management information combined with the virtual machine information to a cloud in which the virtual machine is created.
Abstract:
Disclosed herein are an apparatus and method for accelerating file I/O offload for a unikernel. The method, performed by the apparatus and server for accelerating file I/O offload for the unikernel, includes; executing, by the apparatus, an application in the unikernal and calling, by the thread of the application, a file I/O function; generating, by the unikernal, a file I/O offload request using the file I/O function; transmitting, by the unikernal, the file I/O offload request to Linux of the server; receiving, by Linux, the file offload request from the thread of the unikernel and processing, by Linux, the file I/O offload request; transmitting, by Linux, a file FO offload result for the file I/O I/O offload request to the unikernel; and delivering the file I/O offload result to the thread of the application.
Abstract:
Disclosed herein is an operating method of an apparatus for offloading file I/O of a unikernel based on Remote Direct Memory Access (RDMA). The operating method may include calling, by the application of the unikernel, a file I/O kernel function; generating, by the file I/O kernel function, file I/O information; transmitting, by the unikernel, the file I/O information to a Linux; configuring, by the Linux, a file I/O function using the file I/O information and calling the same; and transmitting, by the file I/O function, a file I/O request, corresponding to the file I/O information, to a file server.
