The document discusses Web 2.0 and service-oriented architecture (SOA). It provides examples of Web 2.0 concepts given by Tim O'Reilly and lists some common Web 2.0 patterns like tagging, mashups, and software as a service. The document also presents a reference architecture for Web 2.0 applications and discusses how SOA and service-oriented clients relate to Web 2.0. It identifies some potential anti-patterns for SOA and Web 2.0 applications.

And previous owner of these…. Puuurrrrr!
And most recently…. Part of a research project to capture knowledge in this book using normative architectural artifacts on Web 2.0.
So what does the future look like? DEMO
So what is Web 2.0? Something that people are struggling to understand No common architecture Multiple definitions Contentious So how can we capture the knowledge?
Where to start?
What architects use to capture knowledge
"Example isn't another way to teach; it's the only way" -- Albert Einstein

Some Web 2.0 patterns? Architectures of Participation Pattern, Small Pieces Pattern, Loosely Joined Pattern, The Platform Pattern, Software as a Service, Data is the Next “Intel Inside”, Ease of Development, Innovation in Assembly, Mashup, Leverage Commodity Economics, Virtualisation: Run on someone else's data center, The biggest pile Pattern, Opting out, not opting in, Voting (explicit and implicit), The Catalog (flickr photos, youtube, mp3), Real Time Auction?, Non-intrusive ads, Front-end/back-end separation reliable back-end, Ease of Development, Embed codes, Redistributable, Self-service (ebay, craigslist), REST, Tags, Comments and community, Plug-in business models, Interfaces, Search, Instant Update (Ajax), Ratings, Service Oriented Architecture (SOA) , Rankings and ways to keep score, The Link, Sensors, Desktop Controller, Reputation systems (pagerank), Blogrolls, Share Buttons, Widgets and Gadgets, Feeds (RSS, Atom, Twitter, FB), The Platform Pattern, Software as a Service, Data is the Next “Intel Inside”, Ease of Development, Innovation in Assembly, Mashup, Leverage Commodity Economics, Virtualisation: Run on someone else's data center, The biggest pile Pattern, Opting out, not opting in, Voting (explicit and implicit), The Catalog (flickr photos, youtube, mp3), Real Time Auction?, Non-intrusive ads, Front-end/back-end separation reliable back-end, Ease of Development
So how does this affect the way you architect your IT Infrastructure?
Web 2.0 Reference Architecture Controller Data/State Management Communication Services Design, Development & Governance Tools Client Application Tier Security Container/Model Virtual Machine Rendering & Media Service Tier Registry- Repository Service Invocation Layer Service Provider Interface Service Container Business Rules/ Workflow Resource Tier EIS Databases Directories ECM Repository Message Queues Legacy Systems Consistent object & event models Consistent architectural models Core Services Standard Technologies & Protocols
Service Oriented Computing Re-purposing core functionality as service to be consumed. But wait! What about the clients? Do they have to be different? Service Oriented Clients (SOC’s)? Service Oriented Clients are, in most cases, Web 2.0 applications!
Service Oriented Clients - Web 2.0 Application Architecture Mashing up multiple formats Using services to deliver rich user experiences Rendering/Media engines let users control the way they use your applications. Are no longer standalone - use knowledge of other users applications.
People are starting to see “BAD” patterns too….
Anti patterns to SOA/Web 2.0? Composite Applications. Based on UML Composition relationship, yes! Aggregate Applications is more accurate. Blob - A large class with too many attributes and is the "heart" of the system. Walled Gardens – the open web is the way to go! Spaghetti code - Program code that has no structure (lots of “goto” statements) Golden Hammer/Swiss Army Knife - Forcing everything to fit a selected tool More?
