Resource Broker

The Resource Broker represents an ad hoc gCube service promoting and supporting the optimal selection and usage of resources during the VRE deployment phase. In particular, it is invoked to select the most appropriate pool of gHNs to be used, among those available in the context of the VRE, during the deployment of the services needed to operate the VRE. Because of this, it interacts with:

• the Information System (IS) to be aware of the available gHNs as well as of their distinguishing features (e.g. the number of Running Instances currently hosted by it, the RAM the machine is equipped with) and
• with the Virtual Organisation Management (VO-Management) to act securely and filter out the gHNs that falls out of the operational context of the VRE. From an architectural point of view it mainly consists of a service implementing the matchmaking algorithm.
