Implementing SOA Design Patterns with WCF

Service Oriented Architecture (SOA) is an architectural design pattern where it’s design is determined by few guiding principles mainly (a) Ser- vice compatibility is determined based on policy (b) Services share schema and contract, not class (c) Services are Autonomous and (d) Boundaries are Explicit. Implementation of these so-called SOA tenants requires a powerful framework which provides a unified programming model, reliable messaging, security, workflow service, interoperability and integration, syndication, meta-data exploration support, service versioning, REST-Ful endpoints and many other modern connected systems features. Both Service-Orientation and the Windows Communication Foundation (WCF) offer the promise of greater interoperability and ease of integration, but in order to realize benefits such as these we must evolve the way we architect solutions.

This session will be a hands-on introduction to SOA with Windows Communication Foundation. Speaker presents patterns using WCF that allows you to define descriptive, maintainable, yet extensible contracts and implementation of SOA tenants. Since SOA promotes loose coupling at the transport layer; you’ll learn how to create loosely coupled systems, the difference between web reference, service reference and channelfactory. The attendees will learn how to avoid anti-Patterns and leverage WCF to create extensible, versioned, responsive, interoperable, and easy-to- maintain services.

The focus of the panel is upon Recruitment and communication i.e. how Anonymous leverages social networks to recruit its members and pick a target, application attack i.e sequence the steps Anonymous hackers deploy to take data and bring down websites, DDoS i.e. the DDoS techniques deployed to take down websites and finally the key mitigation steps that organizations need to take if they ever become a target.

The bottom line is that if it’s a large scale distributed environment, database is the way to go unless you have automated config file management system in place. Keep light-weight config files which rarely change for essentials such as environment-info service to retrieve connection strings or session parameters. For performance, simplicity and ease of use in homogenous non-clustered single server deployments, config files should still do.

The well written and organized book is divided into eight chapters which discuss design patterns, reference models and architecture artifacts. The web 2.0 patterns discussed in the book includes Service Oriented Architecture (SOA), Collaborative Tagging (folksonomy), Synchronized Web, SaaS (cloud computing), Persistent Rights Management, Mashup, Rich User Experience, Participation/Collaboration, Asynchronous Particle Update, ,Semantic Web Grounding and Structured Information. This categorization helps distinguish salient features of a web 2.0 architecture and help define what richness actually means in a rich internet application.
If you have been working in the field long enough, the meme map on page # 63 will help skimming through chapter 3 (which contains web 2.0 example sites) so you can get to the core of the book. Chapters 4 to 7 discuss specific patterns for web 2.0, models, and reference architectures. As mentioned in the book’s title as well as title of this review, “web 2.0 architectures” is focused on big picture architectural overview of the Web 2.0. Even though it’s not a 10000 ft. abstract overview whitepaper, it also does not converse nitty gritty details of building a 2.0 app using jquery and node.js. This text is about concepts, models, reference architectures and common recurring themes in web 2.0 sites. It does not concern itself with specific technologies and implementation details but rather talk about the common paradigm. Therefore, if you are considering it as a cookbook/recipes book for web 2.0 applications, you will be sorely disappointed. However, if you are a web engineer / architect or a technologist interested in the underlying design patterns and attributes of web 2.0, this book is for you.

In any language design, the total time spent discussing a feature in this list is proportional to two raised to the power of its position.
