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)

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.

The following web servers are supported for use with Dispatcher version 4.3.2:

PlatformSupport Level
Apache httpd 2.4.x [1,2]A: Supported
Microsoft® IIS 10 (Internet Information Server)A: Supported
Microsoft® IIS 8.5 (Internet Information Server)Z: Not supported

  1. Web servers built based on the Apache httpd source code have as much support as the version of httpd on which it is based. If in doubt, ask Adobe for confirmation of the support level related to the respective server product. The following cases:

    1. The HTTP server was built using only official Apache source distributions, or
    2. The HTTP server was delivered as part of the operating system on which it is running. Examples: IBM® HTTP Server, Oracle HTTP Server

  2. Dispatcher is not available for Apache 2.4.x for Windows operating systems.

Supported Client Platforms

Supported Browsers for Authoring User Interface

The Adobe Experience Manager user interface works with the following client platforms. All browsers are tested with the default set of plug-ins and add-ons.

The AEM user interface is optimized for larger screens (typically notebooks and desktop computers) and tablet form factor (such as Apple iPad or Microsoft® Surface). The phone form factor is not supported.

NOTE
Support for browsers with rapid release cycles:

Supported Browsers for Websites

Generally, browser support for websites rendered by AEM Sites depends on the implementation of AEM page templates, design and component output, and is therefore in the control of the party implementing these parts.

WebDAV Clients

Microsoft® Windows 7+

When connecting with Microsoft® Windows 7+ to an AEM instance that is not secured with SSL, basic authentication over an unsecured network must be enabled in Windows. It requires a change in the Windows Registry of the WebClient:

  1. Locate the registry subkey:

    • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

  2. Add the BasicAuthLevel registry entry to this subkey using a value of 2 or more.

Additional Platform Notes

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

IPv4 and IPv6

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

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

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®

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

  • 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

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