This topic provides a sample topology for a large-scale deployment. This topology expands on the small-scale deployment topology (described in the Small-scale deploymenttopic).

Note the following characteristics about this topology:

  • This topology focuses on high availability based on load-balancing server clusters for the application servers and failover server clusters for the database server.

  • This topology requires Kerberos authentication. For more information about configuring Kerberos authentication in your Microsoft Dynamics AX environment, see the Installation Guide.

The diagram below shows the sample topology for a large-scale deployment.

The following list describes how the computers in this sample topology are used:

  • An Active Directory domain controller is required for deploying Microsoft Dynamics AX components.

  • Microsoft Dynamics AX Windows clients connecting over a Wide Area Network (WAN) are configured to use Terminal Services to communicate with the AOS. Microsoft Dynamics AX Windows clients on the Local Area Network (LAN) are configured to communicate with the AOS directly.

  • An IIS server cluster can host one or more of the following components:

    • Enterprise Portal

    • Workflow

    • Reporting Services

    • Application Integration Framework (AIF) Web services

  • A BizTalk server cluster provides application integration through the Microsoft Dynamics AX BizTalk adapter. (File system-based and Microsoft Message Queue (MSMQ)-based application integration directly communicates with the AOS.)

  • A single cluster of AOS servers supports clients and application components. You can configure one or more AOS servers in the cluster to act as a batch server.

  • The application file server is deployed on a single server. For high availability considerations, see Application file server topology.

  • Analysis Services and the Reporting Services database are deployed on a dedicated server.

    Caution note Caution

    Reporting Services and Analysis Services are not supported in a failover cluster.


  • A SQL Server failover cluster supports the database requirements for Microsoft Dynamics AX and additional applications, such as:

    • Windows SharePoint Services or Office SharePoint Server (for Enterprise Portal)

    • BizTalk Server

    • Other databases that may be required

      Note Note

      You need to determine if your SQL Server infrastructure supports the workload generated by the Microsoft Dynamics AX application and its associated components. You may need to distribute some of the components, such as the BizTalk database, to a separate SQL Server computer.
