WebGPU doesn't matter at all for OpenFOAM, but maybe you'd need it for rendering in SolidWorks. 8GB of RAM is also really small for the tasks that you're looking to do so I would go for the higher RAM. I have 16GB and it is consumed pretty fast with some demanding tasks like mesh generation and post-processing (mainly using Paraview). WebConsider using a high-availability option, based on your deployment requirements and region. Options include using multiple availability domains in a region and fault domains. Cost. A bare metal GPU instance provides the necessary CPU power for a higher cost. Evaluate your requirements to choose the appropriate Compute shape.
