Work out artifact retention instantly with clear inputs, formula shown and shareable results.
With a fixed retention window, artifact storage reaches a steady state at daily production multiplied by retention days, because expiry balances creation. The policy decision is which artifacts genuinely need long retention: release builds usually do for audit and rollback, while every pull-request build does not, and separating the two typically cuts storage by an order of magnitude.
Artifact storage
steady state = artifacts per day x size x retention days; monthly cost = GB x price per GB-month
Pull-request artifacts for days, mainline builds for weeks, and released versions for as long as you support them — which may be years.
Yes for anything released. Reproducible builds plus immutable storage is what lets you prove which binary was deployed.
