Class CloudInstance

java.lang.Object

org.apache.sysds.resource.CloudInstance

public class CloudInstance
extends Object

This class describes the configurations of a single VM instance. The idea is to use this class to represent instances of different cloud hypervisors - currently supporting only EC2 instances by AWS.
