Configuration Overview #

• Adding and Configuring Resources: During this step, you will add, configure, and indicate to which Resource(s) you wish to manage. Ultimately, the Resources are the “handout answers” to end-user query requests for the hostname. See Work with Resources.
• Adding and configuring Failovers: During this step, you will configure the Resources in a Failover group. See Work with Failovers.
• Adding and configuring Policies: During this step, you will add and configure one or more Policies. The Policy is the act of binding one or more Resources together using a business Rule for the distribution of end-user requests to your added and configured Resources. See Work with Director Policies.
