public interface AmazonEBS
```
Interface for accessing Amazon EBS.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAmazonEBS instead.

You can use the Amazon Elastic Block Store (EBS) direct APIs to directly read the data on your EBS snapshots, and identify the difference between two snapshots. You can view the details of blocks in an EBS snapshot, compare the block difference between two snapshots, and directly access the data in a snapshot. If you're an independent software vendor (ISV) who offers backup services for EBS, the EBS direct APIs make it easier and more cost-effective to track incremental changes on your EBS volumes via EBS snapshots. This can be done without having to create new volumes from EBS snapshots.

This API reference provides detailed information about the actions, data types, parameters, and errors of the EBS direct APIs. For more information about the elements that make up the EBS direct APIs, and examples of how to use them effectively, see Accessing the Contents of an EBS Snapshot in the Amazon Elastic Compute Cloud User Guide. For more information about the supported AWS Regions, endpoints, and service quotas for the EBS direct APIs, see Amazon Elastic Block Store Endpoints and Quotas in the AWS General Reference.

  - startSnapshot
```
StartSnapshotResult startSnapshot(StartSnapshotRequest startSnapshotRequest)

    After creating the snapshot, use PutSnapshotBlock to write blocks of data to the snapshot.
    
    Parameters:
    
    startSnapshotRequest -
    
    Returns:
    
    Result of the StartSnapshot operation returned by the service.

    AWS API Documentation
  - shutdown
```
void shutdown()
```
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
  - getCachedResponseMetadata
```
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
