CloudInstance (Apache SystemDS 3.4.0-SNAPSHOT API)

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.
