Scores of all kinds are integral to how the cluster works. Practically everything from moving a resource to deciding which resource to stop in a degraded cluster is achieved by manipulating scores in some way.

Scores are calculated on a per-resource basis and any node with a negative score for a resource can't run that resource. After calculating the scores for a resource, the cluster then chooses the node with the highest one.

`INFINITY`

is currently defined as 1,000,000 and addition/subtraction with it follows the following 3 basic rules:
- Any value +
`INFINITY`

=`INFINITY`

- Any value -
`INFINITY`

= -`INFINITY`

`INFINITY`

-`INFINITY`

= -`INFINITY`
