Hi @Pavel_Duchovny,
Thank you for responding and thank you for the link.
I see that Private Spaces are currently available only in Heroku Enterprise, which is likely out of reach for the client that I am thinking about approaching. I noticed that there is another add on Dyno available, but it is also kind of pricy.
mLab is still available for the time being. I’m wondering if going this route (with a shared/paid cluster for a production level application), along with a migration to Atlas might work for now. Would this be a stable approach to take?
Thanks again:-)
Juliette
