Resource allocation scenarios

Scope
EGI role
NGIs role
Review
Usage (guaranteed allocation/opportunistic)
Actions/steps
in free hand
address requests below a defined threshold central collector for requests; set up and coordinate the usage of the pool; investigate all the operational aspects; allocate resources;  monitor the effectiveness of the pool resources usage
provide resources directly; act as broker towards the Resource Centers
no review as long as the pool's resources are enough to satisfy all requests. If a review is needed it is up to EGI.eu only to decide
guaranteed allocation for a subset of the pool's resources; opportunistic for the rest After the pool has been set up, EGI collects requests, defines the required operational steps to support the requests; RPs configure their resources that are part of the pool accordingly
right to revoke
address request above the threshold central collector for requests; set up and coordinate the usage of the pool; investigate all the operational aspects; allocate resources;  monitor the effectiveness of the pool resources usage
provide resources directly; act as broker towards the Resource Centers + option to withdraw if national/local policies are conflicting
same as above, but  if a review is needed a very lightweight procedure should be defined, involving EGI.eu and representatives of the RPs contributing to the pool
guaranteed allocation for a subset of the pool's resources; opportunistic for the rest After the pool has been set up, EGI collects requests, defines the required operational steps to support the requests; RPs configure their resources that are part of the pool accordingly
negotiated (elastic pools)
address 'heavy' requests central collector for requests; broker for the RPs resources; define all the technical aspects of the requests; open calls to RPs in order to set up the pool  through the NGIs
broker for the RCs resources; provide support to RCs in order to ease the creation of a pool; monitor the effectiveness of the pool resources usage by the requester
not at all; it is up to the different RPs (NGIs and/or RCs) to decide how many resources (if any) they want to provide to that specific request/user community
the call shall look for resources whose allocation could be guaranteed; in addition opportunistic usage is an added value for each request EGI investigates all the operational aspects, providing a technical descritption of the request (and recipes if necessary) and sets up a call to RPs (throug NGIs) to provide resources for the temporary (elastic) pool dedicated to that request. Then coordinates the setting up of the pools and informs the requester about the conditions for accessing and using the resources
