Amazon WorkSpaces

• Features

  • Amazon WorkSpaces now supports nested virtualization, allowing you to run hypervisors and virtualization-based workloads within your WorkSpaces. You can enable or disable nested virtualization when creating a WorkSpace or by modifying an existing WorkSpace's properties.

S3 Transfer Manager

• Features

  • Use CRT's response file when downloading to a file with the CRT-based S3TransferManager - CRT now writes the object to the destination file directly instead of streaming the body back through the SDK. Pausing such a download uses CRT's new asynchronous pause, so the resume token reflects a fully flushed file.
