The AWS SDK for Java provides a Java API for AWS services. Using the SDK, you can build Java applications that work with Amazon S3, Amazon EC2, DynamoDB, and more.

The AWS SDK for Java 2.x is a major rewrite of the version 1.x code base. It’s built on top of Java 8+ and adds several frequently requested features. These include support for non-blocking I/O and the ability to plug in a different HTTP implementation at runtime.

We regularly add support for new services to the AWS SDK for Java. For a list of changes and featuresin a particular version, view thechange log.
