Starting today, Amazon AppStream 2.0 introduces support for streaming over UDP, when using the Windows native client. Amazon AppStream 2.0 is a fully managed service that provides non-persistent desktops, and application streaming products to end-users. Previously, you were able to stream over TCP via Windows native client. With your end users now working from home or in different countries compared to your corporate offices, they may operate in sub-optimal network conditions you are unable to control. These network conditions can impact your end users experience and productivity. With UDP streaming your end users will experience a more responsive streaming quality in sub-optimal network conditions, with higher round trip latency.

Enabling UDP does not require any changes to your applications, and can simply be enabled from Amazon AppStream 2.0 console. If you opt-in and for any reason an UDP based stream cannot be established we will automatically fall back to TCP based streaming.

To get started with Amazon AppStream 2.0 UDP streaming for Windows native clients, launch the AppStream 2.0 console and go to your Stacks. There you can select UDP as the streaming preference in the Streaming Experience Settings card. In addition to selecting this option you also need to ensure 1/ your network supports UDP streaming on port 8433 for the AWS IP Ranges, 2/ your end users are using the latest Windows native client, and 3/ the base image you are using for your fleet supports UDP. If any of these conditions are not met, we will automatically fall back to streaming over TCP. You can choose to view and edit protocols at a Stack level from AWS Console, APIs or CLI.

UDP based streaming is now available in all regions Amazon AppStream 2.0 is offered in, at no additional charge. AppStream 2.0 offers pay-as-you-go pricing.
