Basic survey setup
The simplest deployment puts Opinio, the web server, and the application server all on a single machine. The database can run on the same host or on a separate server — either works out of the box with Opinio's embedded Apache Derby database or any supported external database.

Advanced survey setup
A more sophisticated configuration where Opinio and its application server run on a dedicated machine, with the web server on a separate host forwarding requests to Opinio. This diagram also illustrates LDAP integration — Opinio can authenticate both survey respondents and admin users against your organization's directory server.

Clustering survey setup
The highest-availability configuration: multiple Opinio instances running as a coordinated cluster. Each node participates as a full cluster member — they share traffic, synchronize data, and maintain a consistent cache, presenting a single coherent survey application regardless of which node serves a request. Requires the Clustered edition license.
