How to run an accelerated computing instance with following requirements?

Assuming NVIDIA T4 works, you can launch Windows Server EC2 instance with g4dn.2xlarge instance type which has 8 vCPUs, 32 GB RAM and 225 NVMe attached instance store. You can specify the EC2 EBS volume size when launching. The g5.2xlarge uses the more powerful NVIDIA A10G GPU.

The blog post Building a high-performance Windows workstation on AWS for graphics intensive applications should get you started. Try NVIDIA-GRID as the display driver to install.

AWS does not offer Windows 11 Pro OS instances or AMIs. In order to use Windows 11 Pro on an instance, you would have to Bring Your Own License (BYOL). You are able to bring your own license to import your own Windows 11 Pro into AWS [1]. For more information on Microsoft Licensing on AWS please refer to [2]. You can achieve this through the use of License Manager [3]. This method would allow you to bring your own license/image and create an AMI based on it. With that AMI you can then launch an instance of your choice.

Secondly, If you require an NVIDIA RTX A4000 GPU card. Unfortunately, AWS currently does not offer that specific card for any of its instances. The G4 instances use a Nvidia T4 card which is slightly older than the A4000. However, AWS does offer up to 8 GPUs for a single instance. Combined may provide the same or better performance than a A4000.
