The Authoritative Guide to Building Service-Oriented Solutions with Microsoft .NET Technologies and the Windows Azure Cloud Computing Platform
InSOA with .NET and Windows Azure,前微软技术专家与Thomas Erl to explore service-oriented computing with Microsoft’s latest .NET service technologies and Windows Azure innovations.
The authors provide comprehensive documentation of on-premise and cloud-based modern service technology advancements within the Microsoft platform and further show how these technologies have increased the potential for applying and realizing service-orientation practices and goals.
Specifically, the book delves into Microsoft enterprise technologies, such as:
- Windows Communication Foundation (WCF)
- Windows Azure
- Windows Workflow Foundation (WF)
- Windows Azure AppFabric
- BizTalk Server
- Windows Presentation Foundation (WPF)
...as well as industry service mediums, including WS-* and REST, and many related service industry standards and technologies.
The book steps through common SOA design patterns and service-orientation principles, along with numerous code-level examples that further detail various technology architectures and implementations.
Topic Areas
This book covers the following primary topics:
- Microsoft Service Technologies
- Microsoft Enterprise Technologies
- On-Premise & Cloud-Based Service Topics
- Industry Service Technologies & Mediums
