Ask HN: How to evaluate a startup's cloud costs?

3 points by tcgv ↗ HN
Hi there!

What would you say are meaningful metrics for startups / tech companies cloud infrastructure costs that one should look into and monitor closely?

So far I have come by the following metrics:

- Cloud Cost as % of Cost of Revenue

- Cloud Cost as % of ARR

- Total Annual Cloud Cost by Company Headcount

Do you think these are useful? Would suggest another metric?

Yup, absolutely useful. Also good for companies to know how they stack among peers in their industry.

Some are more difficult to figure out than others:

  - Cost per tenant/customer
  - Cost by environment
  - Cost of/by change (i.e., introducing changes to app or architecture)
  - Projecting costs into the future
  - Margins, once factoring in other OpEx costs (huge implications given fast rising cloud costs and companies market cap being reduced as a result of increased costs)
  - Pro forma capitalization can also be useful, if not required by some finance teams.
I could go on about this for days...

Also, you should look at these costs with and without the non-production (dev, test, staging, etc.) costs. In some startups, this is easier said than done because they're running everything in a single cloud account. Obviously that is bad for many reasons, but it makes it difficult to attribute costs accurately.
