I agree with @neilh in that AWS can be a little cumbersome. I have used it with the ESP32 platforms in the past via WiFi, but in the end opted for using other end points than AWS. Lots of free dashboards out there for starting out and learning. Most of the really nice ones start adding costs once you decide to scale up the number of data points and devices, but still great for getting off the ground to you hone in what you are trying to achieve..
What were you planning on using for your network transmission device (cell modem, XBee, ESP)???
