Deployment Architecture
The following diagram shows the recommended deployment architecture. In this diagram, the numbering of the servers suggests the order of installation of the various software packages on their respective servers. We recommend that you follow the same order.
Depending on your data storage and the number of concurrent client requirements, you can choose to set up nodes 2, 3, and 4 on a Windows machine and nodes 5, 6, and 7 on a Linux machine. If, however, you choose the minimum-number-of-servers configuration for the deployment, resolve the following possible port conflicts:
- Operations Hub and Plant Applications Web Reports: Operations Hub uses 443 as the port number for https binding. Therefore, use a different port for the Web Reports server.
- Operations Hub IQP and Apache CouchDB: Both these applications use 5986 as the port number. Therefore, modify the default.ini file of Apache CouchDB to set the port number under httpd to 5987.
