[ — SKIP THIS INTRODUCTORY PART — ]

I’m introducing myself to heroku platform (with django). I’m following the Heroku Django tutorial. In tutorial ‘step’ Now we’re ready to scale up a worker: I execute command and this message appears:

(venv)dani@heroku-test:~/hellodjango$ heroku ps:scale celeryd=1
Scaling celeryd processes...

After digging heroku web, I see that the issue is that I should inform about my credit car because running more than one dyno (1 web dyno + 1 work dyno) for an extended period may incur charges

Also, reading tutorial, heroku says that: for production apps, you should use a production-ready embedded webserver Gunicorn and gevent. I appreciate a lot the possibility to scale my application.

Which brings us to …

Hi,

• Can I starting running an application in heroku without “web dyno + work dyno” mode without problems? (just like first part of django quick start or you recommend to upgrade to 15G + 2 dynos = 50€ moth)

You should be able to run your app with a single web dyno for free.
You’ll need to scale up to take on additional traffic though. In order
to scale up you will have to verify your account w/ a credit card.

• For a limited corporate ‘intranet’ application, is heroku a good solution (in money terms)?

Yes. Of course this all comes down to what you think is a reasonable
amount to spend to run your corporate application.

Cheers,
