AEM Applications Multi Layered Architecture

[AEM_Forum]

Hi all,

In Architectures, generally we see different layers like Presentation Layer, Business Layer, Data  Layer, etc.

For AEM Applications, The UI/UX Elements like JSP/Slightly, JS, CSS form the Presentation Layer, OSGI Bundles form the Business Layer, and JCR forms the Data  Layer, I guess.

Is there any diagram and more description for AEM Applications in this direction (What all layers are there, what each layer contains,  what each layer is responsible for, how the interactions take place, etc?

Appreciate your support.

Thanks,

Rama.

Hi Scott,

Your URLs talk about AEM Architecture in terms of product stack.

But, I am trying to see different layers like Presentation Layer, Business Layer, Data  Layer, etc.

In Java world, this is how systems are architected correct?

Thanks,

Rama.

I do not believe we have a diagram like that. You are correct here:

• The UI/UX Elements like JSP/Slightly, JS, CSS form the Presentation Layer - aka - the view
• OSGI Bundles form the Business Layer - like the Model and controlling logic
• JCR forms the Data  Layer

The first bullet is typically the component and the OSGi layer is service, sling models, etc.
