Planning the system topology
Environments for development, testing, and production should be carefully optimized for throughput, response time, scalability, and availability. Under this topic, we will learn about the recommended system topologies for production and non-production environments.
The production system topology
The following diagram shows a layered system topology for large-scale implementation projects:
In the preceding diagram, servers are divided among three main layers. The following table explains the different layers, recommended servers, and their purpose:
|
Layers |
Server |
Purpose |
|---|---|---|
|
Perimeter network layer |
Terminal service cluster |
This provides VPN access to authorized users. |
|
Internet Information Services (IIS) |
This provides access to services for AX through the IIS feature. | |
|
Internet Information Services cluster (IIS cluster) |
This provides Enterprise Portal Support for AX. | |
|
Applications layer |
AOS cluster |
This provides connection to the end users using AX Windows... |
