Release: AWS SDK for .NET 1.5.0

Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With Amazon Glacier, customers can reliably store large or small amounts of data for as little as $0.01 per gigabyte per month, a significant savings compared to on-premises solutions.

This code snippet shows how to create a vault and upload a file.

                                                    
string vaultName = "datasets";
ArchiveTransferManager manager = new ArchiveTransferManager(Amazon.RegionEndpoint.USWest2);
manager.CreateVault(vaultName); // Create a vault to hold all the datasets

string archiveId = manager.Upload(vaultName, "global-wind-patterns-2012.dat", @"c:\datasets\global-wind-patterns-2012.dat").ArchiveId;
Console.WriteLine("Archive ID for later retrieval: {0}", archiveId);

With the new improved support for regions the region can now be specified using a constant in the constructor of the clients. For example, the code below shows how to create an AmazonDynamoDB client using the us-west-2 region:

var dynamoDBClient = new AmazonDynamoDBClient(accessKey, secretKey, RegionEndpoint.USWest2);
                                                                                

The new Amazon S3 File IO API found in the Amazon.S3.IO namespace mimics .NET FileInfo and DirectoryInfo classes to use Amazon S3 as file system. The following code shows how create a directory in a bucket and write a file.

S3DirectoryInfo rootDirectory = new S3DirectoryInfo(client, bucketName);
S3DirectoryInfo artDir = rootDirectory.CreateSubdirectory("asciiart");
S3FileInfo artFile = artDir.GetFile("aws.txt");
using (StreamWriter writer = new StreamWriter(artFile.OpenWrite()))
{
    writer.WriteLine("   _____  __      __  _________");
    writer.WriteLine("  /  _  \/  \    /  \/   _____/");
    writer.WriteLine(" /  /_\  \   \/\/   /\_____  \ ");
    writer.WriteLine("/    |    \        / /        \");
    writer.WriteLine("\____|____/\__/\__/ /_________/");
}                                                                              

The S3FileSystem_Sample sample project was added to the SDK to show a larger example of how to use the API.

Note, when this API is reading and writing data from Amazon S3 it is buffering the data in memory until the stream is closed. For large files this API would not be appropriate.

The object persistence model for Amazon DynamoDB now supports having properties of type Guid and will be persistented as strings in the mapped table.

The PutBucket operation now supports setting an acl.

The new value LogDeliveryWrite was added to the S3CannedACL enumeration for setting permissions to a bucket to be used as logging target.
