Scenario: NetCache deployed in an enterprise environment

About this scenario

This scenario shows a NetCache appliance deployed in a corporation that includes a remote office. This corporation handles Web requests only.

Corporation's goals

The corporation's goals for using Web caching are as follows:

Improve the quality of service because the corporation is interested in its employees being as productive as possible
Reduce bandwidth requirements

Where NetCache appliances are deployed and why

Deployment at the corporate headquarters:

A NetCache appliance was deployed at the corporate headquarters to improve the quality of service and to obtain bandwidth savings. Service is improved by deploying a NetCache appliance because after NetCache fetches a requested object from a Web server the first time, subsequent requests for the same object can be serviced from the cache. This results in a faster response rate than if every request were sent over the slower lines to the Internet. By not having every request sent to the Internet, the goal of reducing bandwidth usage was achieved.

Deployment at the remote office:

The corporation added a NetCache appliance to the remote office to improve quality of service without having to incur the cost of improving the external network. If the corporation did not deploy a NetCache appliance at the remote office, the corporation would have to pay more for bandwidth to improve the quality of service at the remote office or accept slower responses to requests.

Deployment illustrated

The following illustration shows the enterprise's environment with NetCache appliances deployed at both the corporate headquarters and the remote office.
