Do the math.

The hardware paid for itself in 2023. Five years out, DHH counts well over $10M saved.

Where the money went

  • Cloud bill, before$3.2M
  • Cloud bill, 2024$1.3M
  • Own hardware, one-off$700,000

Almost all of the $1.3M left is S3 storage, on a contract that ends in summer 2025.

Still in S3 almost 10 petabytes; "well over a million dollars to keep all this data there"

The catches

  • The figures are the company's own, published by its co-owner; there is no outside audit.
  • One company with its own ops team and workloads that fit a fixed fleet; the post gives the cloud bill and the hardware spend, not a full cost accounting.
  • The 2024 bill still includes S3; the extra $4M is an expectation, not a result.
