Notable changes to Experience Manager Assets as a Cloud Service notable-changes
Adobe Experience Manager as a Cloud Service brings many new features and possibilities to manage your Experience Manager projects. There are many differences between Experience Manager Assets on-premise or hosted as Adobe Managed Service as compared to Experience Manager as a Cloud Service. This article highlights the important differences for Assets capabilities.
The main differences as compared to Experience Manager 6.5 are in the following areas:
Asset ingestion, processing, and distribution asset-ingestion-distribution
Asset upload is optimized for efficiency by enabling better scaling of ingestion, faster uploads, faster processing using microservices, and bulk ingestion. Product capabilities (web user interfaces, desktop clients) are updated. Also, these things may impact some existing customizations.
-
Experience Manager uses direct binary access principle to upload and download assets and uses asset microservices to process asset. See an overview of microservices.
- Asset upload with direct binary access.
- For technical details, see direct binary upload protocol and APIs.
- For a comparison of the available API methods for basic CRUD operations, see APIs and asset operations.
-
The default workflow DAM Asset Update in previous versions of Experience Manager is no longer available. Instead, asset microservices provide a scalable, readily available service that covers most of the default asset processing (renditions, metadata extraction, and text extraction for indexing).
- See configure and use asset microservices
- To have customized workflow steps in the processing, post-processing workflows can be used.
-
The website components that deliver a binary file without any transformation can use direct download. The Sling GET servlet is updated to enable this functionality by default. The website components that deliver a binary with some transformation (for example, resize it via a servlet) can continue to operate as is.
The standard renditions generated with asset microservices are stored in a backward-compatible way in the asset repository nodes using the same naming conventions.
Develop and test asset microservices asset-microservices
Asset microservices provide a scalable and resilient processing of assets using cloud services. Adobe manages the cloud services for optimal handling of different asset types and processing options. Asset microservices help to avoid the need for third-party rendering tools and methods (like ImageMagick) and simplify configurations, while providing out-of-the-box functionality for common file types. You can now process a broad range of file types covering more formats out-of-the-box than what is possible with previous versions of Experience Manager. For example, thumbnail extraction of PSD and PSB formats is now possible that previously required third-party solutions such as ImageMagick. You cannot use the complex configurations of ImageMagick for the Processing Profiles configuration. Use Dynamic Media for advanced FFmpeg transcoding of videos and use processing profiles for basic transcoding of MP4 videos.
Asset microservices is a cloud-native service that is automatically provisioned and wired to Experience Manager in customer programs and environments managed in Cloud Manager. To extend or customize Experience Manager, developers can use existing content or assets with renditions generated in a cloud environment. This ability lets them test and validate their code by using, displaying, or downloading assets.
To do an end-to-end validation of the code and process including asset ingestion and processing, deploy the code changes to a cloud-dev environment using the pipeline and test with full execution of asset microservices processing.
Feature parity with Experience Manager 6.5 cloud-service-feature-status
Experience Manager as a Cloud Service introduces many new features and more performant ways for existing features to work. However, when moving from Experience Manager 6.5 to Experience Manager as a Cloud Service, you may notice that some features either work differently, are not available, or are available partially. The following is a list of such features. In addition, see the deprecated and removed features.
ContentDispositionFilter is to let administrators configure Experience Manager to serve HTML files and to open PDF files inline instead of downloading them. On the publishing instances, you can manage the disposition using the Dispatcher configuration. On the authoring instances, Adobe does not recommend modification to the Content Disposition header. See Content Disposition filter in Experience Manager 6.5.See also
