Verdict
A file upload, transformation, and delivery API with a drop-in picker for 20+ sources, for developers adding file handling to web and mobile apps.
An API-first, developer-configurable content platform with DAM features, built for enterprise teams (100+ users) with in-house developers, not a low-code tool for non-technical editors.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

Billed on
Monthly subscription tiers with bundled resource allowances (bandwidth in GB, uploads counted per file, transformations per file/image operation, storage in GB, number of team members), plus per-unit overage fees once a tier's allowance is exceeded (e.g. Start plan overage is $0.2/GB bandwidth).
Quoted per customer
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.
Bandwidth, storage and user seats, with published per-unit rates above the limits
