Adobe Digital Enterprise Platform in 10 minutes!

For those of you who are new to the Adobe Digital Enterprise Platform (ADEP), the short (but concise) 10 minute video below is a MUST watch, for an introduction to the platform.

Customizing ADEP Solutions – simplified!

Here are some critical aspects that contribute greatly towards the ease of customization of Adobe’s Customer Experience Management (CEM) Solutions.

No EAR deployments and Application server overheads!

The fact that the CEM solutions sit over the OSGi framework (the Apache Felix OSGi container), has completely changed the way they are built and deployed. As compared to the conventional application server model, where one would typically deploy an EAR file, restart the server and wait for an awful long time for the complete server startup, the OSGi model and the new platform brings in the capability to deploy artifacts (bundles and packages) at runtime, without having to bounce the entire server (which anyway is much, much faster). If at all, there may be cases where you would have to restart the OSGi bundles, but that’s a piece of cake given that you have a sophisticated console to do this from, within a few seconds.

Simplified UI changes – Great separation of concerns!

The UI components of all CEM solutions are based on what is known as the Experience Oriented (XOA) architecture. These UI components are popularly known as UX Components, which by definition is a combination of MXML and ActionScript classes that is bundled into SWC files that separate concerns and encapsulate each concern behind an interface. Interfaces make the implementation of concerns (i.e. presentation, domain, etc.) replaceable and extensible. The Presentation layer of each component, further has the separation of a HostComponent and the Skin, such that one can change the UI look-and-feel (for example, re-ordering of UI elements) by simply modifying the Skin of that component, without having to worry about the overall presentation logic (which lies in the HostComponent). Similarly, the component’s Styles are externalized into CSS files, such that one can change the themes, colors, fonts, etc. by simply changing these CSS files. This allows changes to the solutions while still retaining supportability. Apart from these, other enhanced customizations may involve changes to the HostComponents or the Domain layer, as per the desired use case.

Apart from these, the overall development model around customizations on the UI layer, takes-away the overhead of making changes in various different projects. One can now just add the necessary customized artifacts (MXML, Actionscript, CSS, etc.) to the Solution Template projects itself and override the default implementations via CSS definitions and/or standard inheritance. To learn more, refer to this sample scenario from the Correspondence Management solution.

CRX as the Content repository – Ease of debugging!

The solution assets are now stored in CRX, which provides an Apache Jackrabbit based content repository. The nice and intuitive Content Explorer allows an easy way to navigate across the repository to search for your assets (that are clearly visible as nodes, by their names). Users can select an asset or one of its child nodes to see/investigate the properties associated with the asset. One can also download asset content by selecting an asset and clicking on the data property of that asset (for example, for a Layout asset in CM, it is the filexdp property on the layout node). This greatly helps in debugging/troubleshooting assets within the system.

Apart from this, there is also the CRXDE Lite interface that enables you to perform standard development tasks from the browser.

OSGi Services – Possibility of isolated server-side customizations!

Since services deployed in the container are classic OSGi services, one can choose to build/deploy his/her own service as a separate OSGi bundle. Thus, allowing clear separation of custom services vs. the out-of-the-box ones.

Great overall Development Platform!

The Adobe Digital Enterprise Platform (ADEP) offers great tools to support development with ADEP Experience Services. The tools include a set of additional extensions for Flash Builder and a rich SDK (Flex, Java, Mobile) for building applications. The Experience Services SDK is an Experience Package distributed and downloadable using Adobe Package Share.

Overall, since the solutions are built on top of the Adobe Digital Enterprise Platform, they leverage these great capabilities of the platform itself, such that one can build custom applications around it that solves one or more end-to-end use cases.

Comprehensive Help Content!

The solutions publish comprehensive documentation around the usage of the solution, steps to customize areas within the solution, sample customization scenarios, etc. – all of which are a great set of resources to learn about the solution and provide helpful starting points/references for customizations. These learning resources keep evolving as more features are added to the solution, and more scenarios are identified. So, keep an eye on them!
