HA with S3(AWS) Node.Js

Hello HA Community,

I am a Web Dev looking to get started with HA. My first project is an sbc(UDOOx86 advanced plus) w/camera setup using ubuntu 18+ wifi 6 etc… The goal is for me and a small team to connect the 4k live stream to S3(AWS) then to a browser. We are in the planning stages and I was wondering if anyone could give me any pointers or info on past roadblocks they have faced to possibly save us some time. We are mostly JavaScript developers but have some Python partners who can help. Any feedback would be much appreciated. Below is our current MVP HA MVP
