But if they're using a deduplicating storage backend, they can shrink down the actual storage on disk across all customers to something quite reasonable.

- dharmab 7y agoThat only works if Dockerfiles are layered in such a way to maximize caching (many are not and naively pack many changes into a single layer). Yes there are block-level dedupes but that's a transparent feature of most storage systems and not a competitive distinguisher of Hub vs ECR/ACR/Quay.
- grosswait 7y agoI believe the person you replied to was commenting on the advantages to Docker, not the customer, and how (blocklevel is what I inferred) dedupe makes the quantity digestible to Docker's pocketbook.
