We're looking to deploy a couple of Mattermost teams as a trial with some of our customers.
In order to keep overhead low, we're looking at running one Mattermost instance with 3 teams on Heroku + S3. The team sizes will vary between 10 and 100 users.
Does anyone have experience running Mattermost on Heroku? We're trying to make a cost estimate, and it would be helpful to hear what the cost has been for some of the deployments that are currently out there.
