Nee suggestion on hosting a big excel file with multiple formulas

I have a fairly huge excel file ( 25-30MB). Now this has many and complex formulas in multiple tabs. On our local system the file works very slowly, so here are my thoughts on moving onto AWS. Here, performance is the key and perhaps only consideration.

Is it possible to host this on an AWS compute instance, say a windows AMI image? In simple terms can I host this on a windows RDP with high dedicated CPU and then ask users to log in to the RDP and work on the excel there? I do have concurrent users , say around 100 concurrent users and distributed geographical users (currently EU an India but will have to extend to US as well). Please do feel free to suggest any suitable instance/marketplace AMI.

What are the other possible options, keeping in mind concurrent usage and geographical user distribution considerations? Performance is they key and ultimate driver here.
