I use and like Mylio (https://mylio.com/). Does face recognition & syncs to other devices without being in the cloud. I migrated from Aperture/Picasa to Mylio.
Works great for managing my ~200k images. Syncs between my laptop/desktop/phones and also to Google/Amazon drive with optional encryption.
You can define which size of photos are synced to various devices, so my phones have thumbnails, my laptop has preview size photos, and my server/workstations have full copies.
You or I can buy transit from e.g. he.net for ~$0.15/mbit/mo. 10Gbit transit @ $1500/mo will transfer 3PB/mo.
3PB egress on AWS = $157,491.11/mo.
