Nuance Management Center

Chapter 1: Introduction
Physical architecture
The physical configuration of Nuance Management Center includes:
l Application server—The NMC server. Stores user accounts, settings, and administrative information. Can be a
single machine, or, in large installations, can be multiple servers load-balanced by a network traffic switch. Can be
the Nuance-hosted NMC server in the cloud, or a server that you install and host on-premise.
l Database server—Hosts the SQL database that stores your data, like sites, groups, and licenses. Can be the
same physical machine as your application server.
l Dragon clients—Client computers with Dragon Group installed.
If you choose to host your own NMC server on-premise, there are two configuration options:
l Single-tier—Your application server and database server are located on the same physical machine.
l Two-tier—Your application server and database server run on separate machines.
If you're hosting your own NMC server, the installation process installs the NMC server, database server, and NMC
console from a single executable file. During the installation, you can choose the location of your database server.
