How to choose the right technology stack for building custom AEM applications

In today's digital world, organizations need to deliver personalized user experiences to their customers. Adobe Experience Manager (AEM) is a powerful content management solution that enables businesses to build websites, create personalized and interactive documents, and manage multilingual websites. AEM provides a comprehensive set of tools for digital marketing and campaign management, making it an ideal choice for organizations looking to enhance their digital experience management capabilities.

When building custom AEM applications, choosing the right technology stack is crucial. The technology stack refers to the combination of programming languages, frameworks, libraries, and tools used to develop an application. A well-chosen technology stack can greatly enhance the performance, scalability, and maintainability of your custom AEM application. In this article, we will discuss how to choose the right technology stack for building custom AEM applications.

Understanding the Requirements

The first step in choosing the right technology stack for your custom AEM application is to understand the requirements of your project. This involves identifying the goals and objectives of your application, as well as the specific features and functionalities that it needs to support. For example, if your application requires advanced digital asset management capabilities, you may need to consider integrating Adobe Experience Manager Assets into your technology stack.

It is also important to consider factors such as scalability, performance, security, and integration requirements. Determine whether your application needs to handle a high volume of traffic and data, and whether it needs to integrate with other systems or platforms. These factors will help you identify the technologies and tools that are best suited for your custom AEM application.

Evaluating Programming Languages and Frameworks

Once you have a clear understanding of your requirements, it's time to evaluate the programming languages and frameworks that are available for building custom AEM applications. AEM supports multiple programming languages, including Java, JavaScript, and Groovy. Java is the most commonly used language for developing AEM applications, as it provides a robust and scalable platform for enterprise-level applications.

In addition to the programming language, you also need to consider the frameworks that will be used in your custom AEM application. Frameworks provide a structured and efficient way to develop applications and can help you save time and effort. Some popular frameworks for AEM development include Apache Sling, Apache Felix, and Spring Framework.

Choosing the Right Database

The choice of database is another important consideration when building custom AEM applications. AEM supports multiple databases, including Apache Jackrabbit Oak, which is the default database used by AEM. Apache Jackrabbit Oak is a scalable and flexible NoSQL database that provides efficient storage and retrieval of content. However, depending on your specific requirements, you may also consider using other databases such as MongoDB or PostgreSQL.

When choosing a database, consider factors such as performance, scalability, data structure, and integration capabilities. Make sure that the database you choose is capable of handling the volume of data and traffic that your application will generate. It should also be compatible with the other technologies and tools in your technology stack.

Selecting the Right Tools and Libraries

In addition to programming languages, frameworks, and databases, there are several tools and libraries that can enhance the development process of your custom AEM application. These tools and libraries can help you streamline your development workflow, improve code quality, and increase productivity.

Some essential tools and libraries for building custom AEM applications include:

  • Adobe Experience Manager Forms: This tool allows you to create and manage interactive digital experiences and interactions. It provides a visual interface for designing and publishing forms, as well as advanced features such as data validation and integration with external systems.
  • Adobe Content Management: Adobe Content Management is a suite of tools that enable you to manage and author content within AEM. It provides features such as versioning, workflow management, and content localization, making it easier to create and manage multilingual websites.
  • Adobe Experience Manager Assets: This tool is specifically designed for digital asset management and allows you to store, organize, and share digital assets such as images, videos, and documents. It provides features such as asset tagging, metadata management, and integration with Adobe Creative Cloud.
  • Adobe Experience Cloud: Adobe Experience Cloud is a comprehensive set of tools and services for digital marketing and campaign management. It includes tools for analytics, personalization, targeting, and automation, enabling you to deliver personalized user experiences and measure the success of your campaigns.

Considering Cloud Services

Cloud services have become increasingly popular for building and deploying applications, and AEM offers a cloud service known as AEM Cloud Service. AEM Cloud Service provides a scalable and secure environment for hosting your AEM applications in the cloud. It offers features such as automatic scaling, high availability, and integrated monitoring and logging.

When considering cloud services for your custom AEM application, evaluate factors such as cost, scalability, performance, and security. Determine whether your application can benefit from the scalability and flexibility of the cloud, and whether it requires the additional security and compliance features provided by cloud service providers.


Choosing the right technology stack is crucial for building custom AEM applications that deliver personalized user experiences and meet the specific requirements of your organization. By understanding your requirements, evaluating programming languages and frameworks, choosing the right database, selecting the right tools and libraries, and considering cloud services, you can build a custom AEM application that is scalable, performant, and secure.

Remember to regularly review and update your technology stack as new technologies and tools emerge. Stay up to date with the latest trends and best practices in AEM development to ensure that your custom AEM application remains competitive and meets the evolving needs of your organization.
