Image transformation for use in a hybrid distribution architecture with improved performance characteristics is provided herein. The hybrid distribution architecture provides content to clients via a dual source system using a central cloud service and a Content Distribution Network, which uses the cloud service as its source. A client that requests a new rendition of an image provided by a chosen source of the hybrid distribution architecture will have that request handled by the source, and the source may maintain that rendition for future provision. By allowing the client to choose the source and letting that source handle the request, rather than requiring a central service hand the request, the amount of data needed to be transmitted is reduced and the speed of provision of content, modified or not, is improved for the client.

Image transformation in hybrid sourcing architecture

The present disclosure provides for improved computational efficiency in systems used to provide content over a network. Hybrid content sourcing is enabled to provide content via a Content Distribution System (CDN) and a centralized service in conjunction with one another via a single URL provided to client devices. Client devices are provided with expiration tokens, which are used to authorize the CDN to request and serve the content to the client devices with the security inherent to the centralized service. Tenants are thereby enabled to use the CDN as an available source via a single Uniform Resource Locator provided to clients with greater security than public CDNs.

Interchangeable retrieval of sensitive content via private content distribution networks

The present disclosure provides for improved computational efficiency in systems used to provide content over a network. Hybrid content sourcing is enabled to provide content via a Content Distribution System (CDN) and a centralized service in conjunction with one another via a single URL provided to client devices. A hash map is updated and provided to the client devices to allow a tenant to control and change how content is distributed without needing to modify the applications or multiple content items that are used by the client devices. Tenants are thereby enabled to include or exclude the CDN as an available source of content without disrupting operation of the centralized service or the client devices. Individual content assets or libraries of content assets may thereby be interchangeably provisioned via a single Uniform Resource Locator.

Interchangeable retrieval of content

Once a set of inter-dependent items are generated (such as compiled), each of the items is re-named with a content-based name that is generated for each of those items. A version-specific catalog of the inter-dependent items is generated, that maps an item identifier to the content-based name for each item. The re-named items and the version-specific catalogs are loaded to a publication system for consumption.
