WAN Design and Implementation Goals
-Application Availability - Networks carry application information between computers. If the applications are not available to network users, the network is not doing its job.
-Total Cost of Ownership - Information Systems (IS) department budgets often run in the millions of dollars. As large businesses increasingly rely on electronic data for managing business activities, the associated costs of computing resources will continue to rise. A well-designed WAN can help to balance these objectives.
-When properly implemented, the WAN infrastructure can optimize application availability and allow cost-effective use of existing network resources.
