In reply to MeMeMe:
I have an Adobe CC subscription. I have about a Tb of photo's stored on an external hard drive but Adobe allows these (not the raws) to be sync'd to cloud allowing me to view/edit from any device connected to the tinernet.
I also then do weekly back ups onto 2 other hard disks one located at home the other at work. I have a Flickr account but just use this for public sharing of my fav photos. I used to use Backblaze but moved to hard drives as my internet connection was too slow.
For you I think it depends on what you want to achieve...
1. Personal viewing your photos & sharing with friends? (Do you have Amazon prime as this is included)
2. Personal viewing your photos and sharing with the public/friends? (As Flickr but requires payment?)
3. Just back up? (Amazon Prime, Hard drive or Backblaze for example)
Lots of other options as well......
