The 1-server configuration puts all the iMIS systems (except for clients) onto a single server. One box hosts web servers, application servers, and the database server. The size and performance of servers today is such that one robust server can handle the needs of many organizations.
Benefits
■ Easier maintenance and upkeep
■ Lower hosting costs (only a single server)
Considerations
■ No redundancy
■ No way to protect users from spikes in system usage (but less of an issue with robust servers)
Database server and iMIS appserver with support for all iMIS views on a single host
