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 Web application services.

The design was created using the guidance provided in the Reference Blueprints, specifically the Web Application 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 Web Application Services Blueprint, the Web application services design process includes:

During each of these phases, the chosen technology solution may be required to meet specific service-level 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 explained separately in their relevant sections later in the guide.

Who Should Read This Guide

This guide is written for information technology (IT) professionals and system architects who are responsible for designing and implementing Web application services in organizations that are similar in scale and scope to the CDC or SBO scenarios. These professionals include consultants, system architects, and others who are involved in the planning stages of application or infrastructure development across multiple projects.

The guidance provided in this guide should be used in conjunction with the guidance provided in the Service Blueprints to understand the different options and how the choices are relevant to the CDC and SBO scenario requirements. The reader of this guide should be able to understand its technical details and the decisions presented within.

Business Need

Web application services provide the enterprise with a mechanism for offering application interfaces on the Web. Such interfaces may be for external customers, as in the case of an Internet-based service organization, or for internal users or partners using Web applications for sharing information and workflow among various teams or partners.

As described in the Web Application Services Blueprint, Web applications may need to be deployed in a number of different ways based on the mode and type of services that an organization wishes to offer. Each deployment strategy will require a different combination of Web-based and other technologies, and will provide different levels of availability, security, scalability, and performance over the Web.
