    The public DNS name of the instance.
  - publicIpAddress
```
public final String publicIpAddress()
```
    The public IP address of the instance.
    
    Returns:
    
    The public IP address of the instance.
  - privateDnsName
```
public final String privateDnsName()
```
    The private DNS name of the instance.
    
    Returns:
    
    The private DNS name of the instance.
  - privateIpAddress
```
public final String privateIpAddress()
```
    The private IP address of the instance.
    
    Returns:
    
    The private IP address of the instance.
  - status
```
public final InstanceStatus status()
```
    The current status of the instance.
    
    Returns:
    
    The current status of the instance.
  - instanceGroupId
```
public final String instanceGroupId()
```
    The identifier of the instance group to which this instance belongs.
    
    Returns:
    
    The identifier of the instance group to which this instance belongs.
  - instanceFleetId
```
public final String instanceFleetId()
```
    The unique identifier of the instance fleet to which an EC2 instance belongs.
    
    Returns:
    
    The unique identifier of the instance fleet to which an EC2 instance belongs.
  - market
```
public final MarketType market()
```
    The instance purchasing option. Valid values are ON_DEMAND or SPOT.
    
    If the service returns an enum value that is not available in the current SDK version, market will return MarketType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from marketAsString().
    
    Returns:
    
    The instance purchasing option. Valid values are ON_DEMAND or SPOT.

    MarketType
  - marketAsString
```
public final String marketAsString()
```
    The instance purchasing option. Valid values are ON_DEMAND or SPOT.
    
    If the service returns an enum value that is not available in the current SDK version, market will return MarketType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from marketAsString().
    
    Returns:

    MarketType
  - instanceType
```
public final String instanceType()
```
    The EC2 instance type, for example m3.xlarge.
    
    Returns:
    
    The EC2 instance type, for example m3.xlarge.
  - hasEbsVolumes
```
public final boolean hasEbsVolumes()
```
    For responses, this returns true if the service returned a value for the EbsVolumes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - ebsVolumes
```
public final List<EbsVolume> ebsVolumes()
```
    The list of Amazon EBS volumes that are attached to this instance.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEbsVolumes() method.
    
    Returns:
    
    The list of Amazon EBS volumes that are attached to this instance.
