Lumo Service provides storage and fast delivery for static files and media, helping websites and applications serve content from a single source. Its service supports images, video, audio, documents, archives, and application builds, with no restriction on content type. Images can be delivered as originals or previews over HTTPS, with appropriate cache headers. Video and audio are streamed with support for resuming transfers through byte-range requests.

Files remain stored at the source and are distributed through a content delivery network. When a user requests a file, it is served from the nearest point of presence, while the source remains the single location for managing the content. This approach simplifies updates and avoids the need to synchronize files manually across multiple sites. Cache headers are configured at the source, making delivery behavior predictable and verifiable. Lumo Service also provides documentation and guidance on getting connected, offering a straightforward way to distribute static assets and media to users.
