Applied Architecture Patterns on the Microsoft Platform

Overview of this book

Every day, architects and developers are asked to solve specific business problems in the most efficient way possible using a broad range of technologies. Packed with real-world examples of how to use the latest Microsoft technologies, this book tackles over a dozen specific use case patterns and provides an applied implementation with supporting code downloads for every chapter. In this book, we guide you through thirteen architectural patterns and provide detailed code samples for the following technologies: Windows Server AppFabric, Windows Azure Platform AppFabric, SQL Server (including Integration Services, Service Broker, and StreamInsight), BizTalk Server, Windows Communication Foundation (WCF), and Windows Workflow Foundation (WF). This book brings together – and simplifies – the information and methodology you need to make the right architectural decisions and use a broad range of the Microsoft platform to meet your requirements. Throughout the book, we will follow a consistent architectural decision framework which considers key business, organizational, and technology factors. The book is broken up into four sections. First, we define the techniques and methodologies used to make architectural decisions throughout the book. In Part I, we provide a set of primers designed to get you up to speed with each of the technologies demonstrated in the book. Part II looks at messaging patterns and includes use cases which highlight content-based routing, workflow, publish/subscribe, and distributed messaging. Part III digs into data processing patterns and looks at bulk data processing, complex events, multi-master synchronization, and more. Finally, Part IV covers performance-related patterns including low latency, failover to the cloud, and reference data caching.

Pattern description


The organization is trying to streamline data entry into multiple systems that perform similar functions. They wish to take in the same data (an order), but depending on attributes of the order, it should be loaded into one system or another. This looks like a content-based routing scenario.

What is content-based routing? In essence, it is distributing data based on the values it contains. You would typically use this sort of pattern when you have a single capability (for example, ADD ORDER, LOOKUP EMPLOYEE, DELETE RESERVATION) spread across multiple systems. Unlike a publish/subscribe pattern where multiple downstream systems may all want the same message (that is, one-to-many), a content-based routing solution typically helps you steer a message to the system that can best handle the request.

What is an alternative to implementing this routing pattern? You could define distinct channels for each downstream system and force the caller to pick the service they wish to...
