Size build artifacts and the storage retention consumes.
Artifact storage grows as the product of build frequency and retention, which makes it easy to accumulate terabytes unnoticed. Layer deduplication removes most of the redundancy between consecutive builds. Shortening retention for feature branch builds while keeping release artifacts long-term captures most of the saving with no practical loss.
Build Artifact Size
Storage = builds per day × retention days × artifact size × (1 − deduplication saving)
Storage = builds per day × retention days × artifact size × (1 − deduplication saving) Artifact storage grows as the product of build frequency and retention, which makes it easy to accumulate terabytes unnoticed. Layer deduplication removes most of the redundancy between consecutive builds.
Shortening retention for feature branch builds while keeping release artifacts long-term captures most of the saving with no practical loss.
This calculator takes 5 inputs: Size per artifact, Builds per day, Retention period, Saving from layer deduplication, Storage cost per GB per month. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
