Introduction

Windows Server System Reference Architecture (WSSRA) is an integrated set of service solutions based on architectural guidance for typical enterprise scenarios. The Security Architecture Blueprint and Network Architecture Blueprint introduced a number of options to support the deployment of remote connectivity solutions for an enterprise. This guide provides a detailed breakdown of the requirements and exact design choices made for the provision of Remote Access Services (RAS) for the Centralized Data Center (CDC) and the Satellite Branch Office (SBO) scenarios. The Remote Access Services Blueprint outlined the options available for the delivery of remote access services and the technologies available to support these services. As described in that guide, designing a remote access service includes the following design phases:

The technology choices made throughout the design process are required to meet specific service-level goals for criteria such as availability, security, and scalability. These design goals may be incorporated either implicitly or explicitly in the logical or physical design; wherever appropriate, this guide describes how they were incorporated in the design. This guide describes the solution options that were finalized for the development of remote access infrastructures within WSSRA.

Business Need

RAS in the CDC design represents a single location site with remote clients accessing company data through a virtual private network (VPN) tunnel over the Internet. This guide presents the details of technology that was implemented to serve the business requirements identified in the Remote Access Services Blueprint. It also describes how these technologies address the needs. The aim is to be able to provide secure and flexible RAS using low maintenance equipment to minimize operations costs and burden on support staff. These requirements must be balanced with the business criteria for maximizing availability, security, scalability, and manageability within a realistic budget.

The aim for the SBO scenario design is to provide a secure and reliable RAS solution that will link the SBO site to the CDC site. This solution used low maintenance equipment to minimize operations costs and to reduce the burden on the support staff from the CDC site. These requirements must be balanced with the business criteria for maximizing availability, security, scalability, manageability, performance, and supportability within a realistic budget.
