Application Architecture Guide 2.0 BETA 1 - Willy .Net

Introduction
Overview
The purpose of the Application Architecture Guide 2.0 is to improve your effectiveness building
applications on the Microsoft platform. The primary audience is solution architects and
developer leads. The guide will provide design-level guidance for the architecture and design of
applications built on the .NET Platform. It focuses on the most common types of applications,
partitioning application functionality into layers, components, and services, and walks through
their key design characteristics.
The guidance is task-based and presented in parts that correspond major architecture and
design focus points. It's designed to be used as a reference or it can be read from beginning to
end:
• Part I, "Fundamentals," provides you with the fundamentals to understand architecture
design techniques and strategies.
• Part II, "Design,” provides overarching design guidelines and best practices that can be
applied to any application type or application layer, including how to design communication
and plan for services.
• Part III, "Layers,” provides architecture and design approach as well as best practices for
each layer, including presentation, business, service, and data access.
• Part IV, "Quality Attributes,” provides specific guidance on quality attributes such as
security, performance, etc.
• Part IV, "Archeytpes – Design and Patterns,” provides patterns and design frames for each
application type archetype, including service applications, web applications, rich client
applications, rich internet applications and mobile applications.
Why We Wrote This Guide
We wrote this guide to accomplish the following:
• To help you design more effective architectures on the .NET platform.
• To help you choose the right technologies
• To help you make more effective choices for key engineering decisions.
• To help you map appropriate strategies and patterns.
• To help you map relevant patterns & practices solution assets.
Scope
This guide provides principles, patterns, and practices for designing application architectures on
the .NET platform. It’s a principle-based approach. The overall scope of the guide is shown in
