Class Allocator
java.lang.Object
be.ac.ua.broker.allocation.Allocator
public class Allocator
- extends java.lang.Object
This class is used during the resource allocation phase of the broker. For
every instance on which certain task hours were scheduled in the previous
phase of the broker, is determined what pricing model will be used and the
actual prices are coupled to the schedule. There are different options
available, only on-demand instances, no spot instances, spot-enabled (which
uses the spot model to determine the bid) and spot-optimal (which used the
actual spot price history to determine the bid).
