Once you really get going, Heroku is expensive, but it might be worth the cost for teams (or individuals) that don't have the time (or expertise) to effectively manage a production deployment (security, up-time, backups, etc.).
Surely, there are many ways of deploying meteor apps, but no true simple way (which is why i expected a lot from galaxy). Like a single production line: create > develop > deploy w/ scalable infrastructure and cost. That was the whole meteor attractiveness for me.
There was a meteor based project where i spent 2 weeks developing a prototype and almost a month trying different deploy setups with the client. (heroku, digital ocean, linode, modulus, compose, aws, etc...)
Now, with ember or react + firebase, i can do the same stuff at a fraction of the cost and without having to learn devOps.
Appreciate your answer :)
