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.

Building the solution


In this solution, we will be constructing a Message Bus pattern for processing Purchase Orders using BizTalk Server 2010 and the ESB Toolkit. We are implementing a single message flow to illustrate an example of how the ESB functionality can be leveraged. Our system will be loosely coupled and will use WCF-BasicHttp and WCF-WSHttp as the transport adapters of choice.

We will use the WCFTestClient tool to initiate PO Requests, which will then be processed by BizTalk/ESB Server. Our BizTalk/ESB Server will query the inventory server and customer server to determine whether the items requested are in stock and the customer meets the required credit limit. The credit limit is fixed across all customers and will be implemented within BizTalk. Based on the information received, BizTalk will approve/reject the purchase order appropriately. The main components are illustrated in the following diagram :
