Section 1: AEM Development Basics

1.1 Understanding AEM Architecture

Adobe Experience Manager (AEM) operates on a modular architecture, making it both scalable and customizable. Let’s break down its core components:


At the heart of AEM is the JCR (Java Content Repository), which stores all the content, metadata, and code. The repository is the backbone of your AEM experience.

OSGi Framework

The OSGi (Open Service Gateway Initiative) Framework allows for modular development. In AEM, bundles are the individual components packaged in a JAR file that can be started, stopped, and configured independently.

Servlet Engine

AEM sits on top of a Servlet Engine (like Apache Tomcat), which is responsible for handling client requests and returning responses.


The dispatcher acts as both a load balancer and a caching engine. It aids in enhancing the website’s security, performance, and resilience.

By understanding the architecture, developers can make informed decisions about how best to customize and extend AEM functionalities.

1.2 AEM Development Tools and Extensions

When it comes to AEM development, the right set of tools can significantly streamline your workflow. Here are some indispensable tools and extensions:

AEM Developer Tools for Eclipse

This Eclipse plugin simplifies the development and deployment of AEM projects, offering features like seamless repository synchronization.


This is a lightweight IDE (Integrated Development Environment) provided by AEM for quick and straightforward development tasks.

Adobe Cloud Manager

This cloud-based service offers CI/CD (Continuous Integration/Continuous Delivery) capabilities, simplifying testing and deployment processes.


This tool can be integrated into your workflow for continuous inspection of code quality.


AEM projects often use Apache Maven for automating the build process, managing dependencies, and facilitating the project’s build infrastructure.

These tools are invaluable in crafting well-structured, efficient, and maintainable AEM solutions.

1.3 Guide to AEM Templates and Page Components

In AEM, templates and page components serve as the building blocks for your digital experiences.


A template defines the structure of a page. It acts as a blueprint that authors can use to create pages. AEM offers both editable and static templates, giving developers and authors a flexible canvas to work on.

Page Components

Page components are reusable pieces of UI (User Interface) that can be dragged and dropped into templates. These can range from simple text fields to complex carousels and accordions.

Importance of Templates and Components:

  • Speed Up Development: Reusable components mean you don’t have to build everything from scratch, thereby speeding up the development process.
  • Consistency: Using a defined set of templates and components ensures a consistent look and feel across the website.
  • Authoring Experience: The drag-and-drop nature of components allows for a more user-friendly experience for content authors.

In summary, mastering the usage of templates and page components is vital in AEM, as they offer a mix of flexibility, reusability, and consistency that is essential for effective web development.

By understanding these basic elements of AEM development, you’re already on your way to becoming proficient in the platform. In the next sections, we’ll dive deeper into tips, best practices, and advanced techniques to further enhance your AEM development skills.
