AOS in AX & D365FO
The Microsoft Dynamics AX / D365FO (Finance & Operations) Object Server (AOS) is the second-tier application server in the Microsoft Dynamics AX three-tier architecture.
The AX 2012 3-tier environment is divided as follows:
- First Tier – Intelligent Client
- Second Tier – AOS
- Third Tier – Database Server
In D365FO N-tier environment is divided as follows:
- X-Tier – AOS, and Batch servers
- X-Tier – Database Server
In an N-tier solution, the database runs on a server as the X tier; the AOS handles the business logic, Batch jobs/ background process in multiple tiers, and handles the user interface and necessary program logic.
An Application Object Server (AOS) is a core component of the Microsoft Dynamics AX installation and is installed by using Setup. An AOS enforces security, manages connections between clients and the database, and provides the foundation where business logic for Microsoft Dynamics AX is executed.
