 4 * Additional convenience implementation on top of {@link Cloud} that are likely useful to
 5 * typical {@link Cloud} implementations.

 7 * <p>
 8 * Whereas {@link Cloud} is the contract between the rest of Hudson and a cloud implementation,
 9 * this class focuses on providing a convenience to minimize the effort it takes to integrate
10 * a new cloud to Hudson.
