Resource Reservation (Erl, Naserpour)
How can shared IT resources be protected from conflicts that can arise from concurrent access?
When two or more cloud service consumers attempt to instantiate the same shared IT resource, runtime conflicts can occur, including resource constraints due to lack of capacity.
A system is established whereby a portion of an IT resource (or one or more IT resources) is set aside exclusively for a given cloud service consumer.
The resource management system is used to define IT resource thresholds and to restrict access to reserved IT resources.
