My boss suggested we use Cloudinary as an alternative to mySQL db. I found cloudinary to be pretty good and setting it up and integrating it to my micro-service was pretty easy.

FWIW: I thought it would be an interesting experiment to try resolving into Cloudinary directly from the GraphQL service. Turns out they have pretty restrictive rate-limiting on their Admin API, so we had to cache all the image data in a database anyway. 😅
