CloudProviderRanker is a standalone REST WEB Service which ranks cloud providers basing on rules implemented with the Drools framework
The CloudProviderRanker checks if preferences have been specified; if they have, then they have absolute priority over any other provider's information (like monitoring data).
If preferences are not specified, for each provider the rank is calculated as sum of SLA's rank and a combination of monitoring data, each of them conveniently normalized with weight specified in a Ranker's configuration file.
