AWS Workpaces Desktop

I purchased AWS Workspaces as my home Cloud computer (although it is free for a while) and started using it. The OS I chose this time is called AWS Linux, but if you usually use Windows OS and choose Windows for Workspaces, you can use it as a normal computer without much discomfort. AWS Linux seems to be based on RedHat, and the desktop is GNOME2-based MATE. However, it seems to be almost complete, and for the original purpose of using Workspaces, it would be best to use it as it is.
The only major applications installed from the start are the open source LiberOffice and Firefox, but of course necessary applications can be easily added with yum. However, there seems to be some AWS etiquette in yum.
When I tried to play youtube on Firefox, the picture quality was very good rather tham my expectation, with just a little bit of choppiness if you don’t set it to full screen. And the sound played without any problems without any additional settings. This was a surprise to me, a Linux geek until about 10 years ago. I remember that back then, it was normal to not be able to play sound when connecting by VNC, and even if you forced playback of video, it was useless in terms of computer resource and network quality. The combination of the AWS Workspaces server and the client application must have been perfected.
However, this time I only confirmed that I could play Youtube and other videos on Cloud PC, and I will not use it because the FireTV connected to my TV is for everyday use, as it is still better quality in terms of picture and sound (:-).
