hi @Albin_Issac  - we noticed that upload API usually is taking a lot of time even for creating 1 image of 50MB, so thought of exploring more options. 

AssetManager.createOrUpdateAsset method is deprecated in latest SDK @giuseppebag. That is why, we were thinking to use pre-process step as asked above.

Thank you so much for your response @daniel-strmecki 

Our client is on AEM 6.5 on prem version and wants to migrate to AEMaaCS. During initial discussion - we were asked to ensure if AEMaaCS would support the Cloudfare integration for CDN or not. Is there any Adobe references that we can use to understand this ?
