What Web Server Does AEM?

Adobe Experience Manager (AEM) is a powerful content management system that allows you to create, manage, and deliver personalized digital experiences. When it comes to serving web content, AEM can work with different web servers depending on your specific requirements.

Apache HTTP Server

The most common web server used with AEM is Apache HTTP Server. Apache is a robust and open-source web server that provides a reliable platform for hosting AEM applications. It offers excellent performance, security, and scalability, making it a popular choice among developers.

Configuring Apache HTTP Server with AEM involves setting up virtual hosts to handle different websites or domains. This allows you to serve multiple AEM instances on a single server while ensuring proper separation and control over each website’s content and configuration.

Adobe Dispatcher

In addition to Apache HTTP Server, Adobe Dispatcher plays a crucial role in serving AEM content efficiently. Dispatcher is a caching and load-balancing tool provided by Adobe that integrates seamlessly with AEM.

Dispatcher sits between the web server (such as Apache) and the AEM instance, acting as a reverse proxy. It caches frequently accessed static content like images, CSS files, and JavaScript files, reducing the load on the AEM server and improving overall performance.


The caching feature of the Adobe Dispatcher significantly improves the response time for subsequent requests by serving cached content directly from memory instead of fetching it from the backend AEM server again. This results in faster page load times and better user experience.

Load Balancing

In scenarios where you have multiple instances of AEM running behind a load balancer for high availability or scalability purposes, Adobe Dispatcher efficiently distributes incoming requests across these instances. This ensures a balanced workload and prevents any single instance from being overloaded.

Other Web Servers

While Apache HTTP Server and Adobe Dispatcher are commonly used with AEM, it’s worth noting that AEM can also work with other web servers like Microsoft IIS, Nginx, or even cloud-based solutions like Amazon Web Services (AWS) Elastic Load Balancer.

These web servers offer similar functionalities in terms of serving AEM content, but the configuration and setup may vary slightly depending on the specific server you choose.


In summary, Adobe Experience Manager (AEM) can work with various web servers to serve your digital experiences. Apache HTTP Server is the most popular choice due to its performance and versatility.

Adobe Dispatcher further enhances performance by caching frequently accessed content and load balancing requests across multiple AEM instances. However, other web servers like Microsoft IIS or Nginx can also be used effectively with AEM. Consider your specific requirements and choose the appropriate web server that best fits your needs.
