Web workers
Production:

• Low-end, 2 standard-2x dynos, with-auto-scaling up so we’ll add on a bit for that. (not recommended, let’s call it $120/month).

• A single performance-m dyno with auto-scale to 2 ($250/month maybe),

• a performance-l ($500/month)

Staging:

1 standard-2x dyno, at $50

This is deciding that staging will be slower than production – can always temporarily increase it if we need to for testing things, and pay per-minute.

Background workers

Production:

• 2 standard-2x ($100) with auto-scaling up. Hard to predict actual auto-scaling charges, let’s call it $150 total.

Staging:

• 1 standard-2x ($50)

• Maybe with auto-scaling? Should we call it $80 on the high-end?

Database

Heroku postgres standard-0 ($50), 2x for production and staging.

Redis
One heroku redis premium-0 ($15), 2x for production+staging

Future: We might want a second redis premium-0 to use for caching.

$60

Solr
SearchStax. Either an NDN1 ($20/month with annual contract) or NDN2 ($40 with annual contract). x2 for production and staging.

$40

$80

Autoscaling

hirefire.io. $15/month, or $25/month with “overclocking”.

Does not include minutes of scaled dynos, just the autoscaler itself.

Don’t plan to use autoscaling on staging.

$25

Logging

Papertrail, not entirely clear what tier we need for our traffic, we’re guessing the $16 or $30 plan.

Add 15% margin

Hard to estimate costs including:

• one-off dynos charged per-minute for scheduled tasks, developer console, rake tasks.

• Minutes in use of auto-scaled dynos beyond minimums.

• Just things we didn’t account for, put in some wiggle-room.
