Content transformation includes transforming of content items 104 in a content management system (CMS) repository from a source format to a target format. The transformations can be performed using a transformation/computing node cluster 110 having multiple nodes, each of which is configured for a specific content transformation type (e.g. PDF transformations, image processing). Router nodes 112 can receive requests for content items and route content items to transformation nodes that are configured for a specific content transformation type to either transform a requested content item to the target format or perform an intermediate transformation as part of a transformation chain. The transformation node cluster 110 can be dynamically configurable based on estimates of expected loads for the various types of transformations. The transformation nodes maybe assigned among available defined transformations to increase efficiency if a threshold metric such as wait times are crossed. Load balancing can be accomplished automatically as the router nodes 112 direct content items for transformations simply based on their current and target content formats. |
