AEM as a Cloud Service Assets (AEMCS Assets) introduces a new method for processing assets, Asset Compute. With Asset Compute, newly uploaded assets are processed in the Adobe Runtime I/O microservice framework.
The advantage to this new architecture, is that this offloads the CPU and memory-heavy work of rendering renditions and reading metadata from binaries to a scalable, cloud framework vs being limited by (and even overwhelming) the server running AEM.
Along with this new architecture, a new feature in AEM Cloud Service Assets is that you can request reprocessing of assets. Reprocessing will send the assets through the entire processing flow, regenerating all renditions and overriding the metadata with newly extracted metadata from the asset. To reprocess assets, select an asset (or a folder) and click the reprocess button:
Select Assets for Reprocessing
Then configure how you want the assets to be reprocessed. You can change the processing profile to use when processing the assets and select whether or not to run the post-processing workflows.
