Verdict
A developer-first file upload and CDN/media-processing API for apps, pitched as a lighter, faster-to-integrate alternative to Cloudinary for teams that don't need its full DAM/video/AI stack.
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.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A CDN and edge-computing platform bundling storage, video streaming, DNS and image optimization, aimed at developers and cost-conscious teams as an alternative to larger CDN providers.

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.
Primarily pay-as-you-go per GB of bandwidth/storage (CDN from $0.01/GB standard, volume network from $0.005/GB down to $0.002/GB; Storage from $0.01/GB standard tier, $0.02/GB edge SSD tier; Stream storage from $0.01/GB and CDN from $0.005/GB), with a $1/month account minimum. Bunny Optimizer is a flat $9.50/month per website (unlimited optimizations). No per-request fees. Enterprise-scale volume (above 2PB) requires contacting sales.
