Free software, no licence fee
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.
Credits: one credit is 1,000 transformations, or 1 GB of storage, or 1 GB of video bandwidth

Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price
