Choosing a Deployment Model

The way you deploy SNA Server throughout your enterprise depends greatly on your existing network infrastructure and the location of the users who require host access.

SNA Server can be deployed using three models:

• Branch, in which SNA Server computers are placed away from the host system and near your users

• Centralized, in which SNA gateways are placed close to the host system

• Distributed, in which SNA gateways are placed both near the host system and close to your users

The three models can also be combined to achieve the best configuration for your enterprise.

This section explores each deployment model’s strengths and weaknesses.
