Introducing the AWS SDK for C++

My colleague Jonathan Henson sent me a guest post to introduce a brand-new AWS SDK!

— Jeff;

After a long effort, we are proud to announce an open-source C++ SDK for scaling your native applications with Amazon Web Services.

The AWS SDK for C++ is a modern C++ interface with lightweight dependencies. We designed it to be fully functioning, with both low-level and high-level interfaces. However, we also wanted it to have as few dependencies as possible and to be platform-independent. At the moment, it includes support for Windows, OS X, Linux, and mobile platforms.

This SDK has been specifically designed with game developers in mind, but we have also worked hard to maintain an interface that will work for systems engineering tasks, as well as other projects that simply need the efficiency of native code.

Features

• Works with the Standard Template Library (STL).
• Custom memory management support.
• C++ 11 features used and supported.
• Builds with CMake and your native compiler toolchain.
• Lightweight dependencies.
• Exception-safe.
• Extensive, configurable logging.
• Default credentials providers.
• Identity management through Amazon Cognito Identity.
• High-level Amazon S3 interface through TransferClient.
• Uses native OS APIs for cryptographic and HTTP support.

Code Samples

Storing a value in a Amazon DynamoDB table:

Aws::DynamoDB::DynamoDBClient dynamoDbClient;
PutItemRequest putItemRequest;
putItemRequest.WithTableName("TestTableName");
AttributeValue hashKeyAttribute;
hashKeyAttribute.SetS("SampleHashKeyValue");
putItemRequest.AddItem("HashKey", hashKeyAttribute);
AttributeValue valueAttribute;
valueAttribute.SetS("SampleValue");
putItemRequest.AddItem("Value", valueAttribute);
auto putItemOutcome = dynamoDbClient.PutItem(putItemRequest);

if(putItemOutcome.IsSuccess())
{
    std::cout << "PutItem Success Using IOPS " << putItemOutcome.GetResult().GetConsumedCapacity();
}
else
{
    std::cout << "PutItem failed with error " << putItemOutcome.GetError().GetMessage();
}

Downloading a file from Amazon Simple Storage Service (Amazon S3):

Aws::S3::S3Client s3Client;
GetObjectRequest getObjectRequest;
getObjectRequest.SetBucket("sample_bucket");
getObjectRequest.SetKey("sample_key");
getObjectRequest.SetResponseStreamFactory(
    [](){
        return Aws::New(ALLOCATION_TAG, DOWNLOADED_FILENAME, std::ios_base::out | std::ios_base::in | std::ios_base::trunc);
    });
auto getObjectOutcome = s3Client.GetObject(getObjectRequest);
if(getObjectOutcome.IsSuccess())
{
    std::cout << "File downloaded from S3 to location " << DOWNLOADED_FILENAME;
}
else
{
    std::cout << "File download failed from s3 with error " << getObjectOutcome.GetError().GetMessage();
}

It’s that simple! Download the code from GitHub today and start scaling your C++ applications with the power of Amazon Web Services.
