Stickup Cam accessing Amazon IP

My Stickup Cam attempted to access an external IP, 52.21.2.135 A search indicates this IP belongs to Amazon in Texas. Why? Has my camera been hacked? Is it sending back proprietary information? Or is this how it records videos. This action was shown on a recent security scan and has not been shown for my other cameras.

Hi neighbor! Your Stick Up Cam attempted to access AWS servers that we use to provide the Ring services. Your Ring device communicates with AWS in order to function. AWS is also where Ring video recordings are stored for subscribers of a Ring Protect Plan. Rest assured, this is expected behavior for your device. If you have any further questions, please let me know.
