Introduction

Windows Server System Reference Architecture (WSSRA) is an integrated set of service solutions based on architectural guidance for typical enterprise scenarios. This guide focuses on the design of the firewall and proxy services solutions.

The design was created using the guidance provided in the Firewall Services Blueprint. The designs detailed in this guide were formulated using real world scenario specifications, specifically the Centralized Data Center (CDC) and Satellite Branch Office (SBO) scenarios based on the Contoso business case study. These scenarios are outlined in the Introduction to Windows Server System Reference Architecture document, and a further level of detail is provided in the Lab Implementation of Windows Server System Reference Architecture document.

As described in the Firewall Services Blueprint, the following three elements of the solution are covered in this blueprint:

Each of these chosen technology solutions needs to meet specific service-level goals for design goals such as availability, security, and scalability. How these design goals are incorporated may either be implicit in the logical or physical design or they may be explained in separate sections later in this guide.
