MongoDB is a third-party software program and is not included in the AEM licensing package. For more information, see the MongoDB licensing policy page.
To get the most of your AEM deployment with MongoDB, Adobe recommends licensing the MongoDB Enterprise version to benefit from professional support. See Recommended Deployments for more information.
The license includes a standard replica set, which is composed of one primary and two secondary instances that can be used for either the author or the publish deployments.
In case you want to run both author and publish on MongoDB, two separate licenses must be purchased.
Adobe Customer Care assists qualifying issues related to the usage of MongoDB with AEM.
For more information, see the MongoDB for Adobe Experience Manager page.

    • libXau.x86_64 (1.0.8-2.1.el7)
    • glibc-locale.x86_64 (2.17 or later)

Virtual & Cloud Computing Environments virtual-cloud-computing-environments

Adobe Experience Manager is supported running in a virtual machine on cloud computing environments. These environments include as Microsoft® Azure and Amazon Web Services (AWS), running in compliance with the technical requirements listed on this page, and according to Adobe’s standard support terms.

For a cloud-native environment, review the latest offering from the AEM product line: Adobe Experience Manager as a Cloud Service. See Adobe Experience Manager as a Cloud Service Documentation for details.

Adobe also offers Adobe Managed Services to deploy AEM on Azure or AWS. Adobe Managed Services provides experts with experience and skills of deploying and operating AEM in these cloud computing environments. See additional documentation on Adobe Managed Services.

In all other cases of deploying AEM on Azure or AWS, or any other cloud computing environment, support from Adobe is contained to the virtual compute environment. That virtual environment must be run in compliance with the technical specifications listed on this page. Any reported issue relative to AEM running in any of these cloud environments must be reproducible independently from any cloud service specific to the cloud computing environment. That is, unless the cloud service is supported as part of the technical requirements listed on this page, for example, Azure Blob storage or AWS S3.

For recommendations on how to deploy AEM on Azure or AWS, outside of Adobe Managed Services, Adobe recommends working directly with the cloud provider. Or, working with Adobe partners supporting the deployment of AEM in the cloud environment of your choice. The selected cloud provider or partner is responsible for the sizing specifications, design, and implementation of the architecture, to meet your specific performance, load, scalability, and security requirements.

Dispatcher Platforms (Web Servers) dispatcher-platforms-web-servers

The Dispatcher is the caching and load-balancing component. Download the latest Dispatcher version. Experience Manager 6.5 requires Dispatcher version 4.3.2 or higher.

Additional Platform Notes additional-platform-notes

This section provides special notes and more detailed information about running Adobe Experience Manager and its add-ons.

IPv4 and IPv6 ipv-and-ipv

All elements of Adobe Experience Manager (Instance, Dispatcher) can be installed in both IPv4 and IPv6 networks.

Operation is seamless as no special configuration is required. You specify an IP address using the format that is appropriate to your network type, if necessary.

When an IP address must be specified, you can select (as required) from the following:

  • An IPv6 address. For example, https://[ab12::34c5:6d7:8e90:1234]:4502

  • An IPv4 address. For example, https://123.1.1.4:4502

  • A server name. For example, https://www.yourserver.com:4502

  • The default case of localhost is interpreted for both IPv4 and IPv6 network installations. For example, https://localhost:4502

Requirements for AEM Dynamic Media Add-on requirements-for-aem-dynamic-media-add-on

AEM Dynamic Media is disabled by default. See here to enable Dynamic Media.

With Dynamic Media enabled, the following additional technical requirements apply.

NOTE
These system requirements only apply if you use Dynamic Media - Hybrid mode; Dynamic Media - Hybrid mode has an embedded image server, which is only certified on certain operating systems.
For Dynamic Media customers who run Dynamic Media - Scene7 mode (that is, dynamicmedia_scene7 run mode), there are no additional system requirements; only the same system requirements as AEM. Dynamic Media - Scene7 mode architecture uses the cloud-based image service and not the service embedded in AEM.

Hardware hardware

The following hardware requirements are applicable for both Linux® and Windows:

  • Intel Xeon® or AMD® Opteron CPU with at least four cores
  • At least 16 GB of RAM

Linux® linux

If you are using Dynamic Media on Linux®, the following prerequisites must be met:

  • Red Hat® Enterprise 7 or CentOS 7 and later with latest fix patches
  • 64-bit Operating System
  • Swapping disabled (recommended)
  • SELinux disabled (See note that follows)
NOTE
If the locale is set such that LC_CTYPE is not equal to en_US.UTF-8, it prevents Dynamic Media from working. To see what its value is, type “locale” at the command prompt. If it is not set properly, then set the LC_CTYPE environment variable to the empty string by typing “export LC_CTYPE=” before running AEM.
NOTE
Disabling SELinux: Image Serving does not work with SELinux turned on. This option is enabled by default. To remedy this issue, edit the /etc/selinux/config file and change the SELinux value from:
SELINUX=enforcing to SELINUX=disabled
NOTE
NUMA Architecture: Systems with processors featuring AMD64 and Intel® EM64T are typically configured as non-uniform memory architecture (NUMA) platforms. That is, the kernel constructs multiple memory nodes at boot-time rather than constructing a single memory node.
The multiple node construct can result in memory exhaustion on one or more of the nodes before other nodes become exhausted. When memory exhaustion happens the kernel can decide to kill processes (for example, the Image Server or Platform Server) even though there is available memory.
Therefore, Adobe recommends that if you are running such a system that you turn off NUMA using the numa=off boot option to avoid the kernel killing these processes.
NOTE
Server host name must resolve: Ensure that the host name of the server is resolvable to an IP address. If that is not possible, add the fully qualified host name and the IP address to /etc/hosts:
<ip address> <fully qualified hostname>

Windows windows

  • Microsoft® Windows Server 2016
  • Swap space equal to at least twice the amount of physical memory (RAM)

To use Dynamic Media on Windows, install Microsoft® Visual Studio 2010, 2013, and 2015 redistributable for x64 and x86.

For Windows x64:

For Windows x86:

macOS macos

  • 10.9.x and later
  • Only supported for trial and demo purposes
