All Implemented Interfaces:

Serializable, Cloneable
```
public class JobFlowInstancesConfig
extends Object
implements Serializable, Cloneable
```
A description of the Amazon EC2 instance running the job flow. A valid JobFlowInstancesConfig must contain at least InstanceGroups, which is the recommended configuration. However, a valid alternative is to have MasterInstanceType, SlaveInstanceType, and InstanceCount (all three must be present).
