What they offer for $250 per process can be done at $60/mo per whole app.
When I helped them move all background workers and all non-production apps to Digital Ocean they ended up saving $7k/mo which blew my mind.
It is easy to start on Heroku, but staying there is a black hole in any budget.
Thankfully we've built Heroku Config Vars sync so one can move off of Heroku gradually.
only if developer/devops/admin time is free and for most it isnt. if 60 vs 250 /month is a breaking factor for you and your use case: go for it. if you need the software deployed to make real business it just doesnt matter.
No wonder AWS can get away with the prices they have since people like you (and many more VC funded startups) simply have zero care about the price.
For people who run "real" businesses (meaning you need to have a larger income than expense [meaning, everything not VC-funded]), price is always a part of the calculations, even when it comes to hosting.
