Deployment Options
The various components of QAD Enterprise Applications and QAD QXtend can be deployed in several configurations:
On a single host in a unified (single-tier) deployment
On multiple hosts in a distributed (multi-tier) deployment
In a single-host environment, all logical tiers are on the same host, and can therefore run at the same time. In a multiple-host environment, hosts physically separate the logical tiers. Run the installer on each host involved in the installation.
