Web 2.0 phenomenon Web 1.0 Web 2.0 DoubleClick --> Google AdSense   Web 2.0 DoubleClick --> Google AdSense Ofoto Flickr Akamai BitTorrent mp3.com Napster Britannica Online Wikipedia personal websites blogging evite upcoming.org and EVDB domain name speculation search engine optimization page views cost per click screen scraping web services publishing participation content management systems wikis directories (taxonomy) tagging ("folksonomy") stickiness syndication

Web 2.0 phenomenon collaboration, participation, trust vs. publishing wikipedia, ebay ranking search vs. catalog; tag vs. directory server-side gmail, flickr, del.icio.us blogging RSS – subscription “geoweb” web services (service-oriented architecture) “mashup” …and certainly web services, services-oriented architecture is a part of this whole phenomenon we call “Web 2.0”. Due to the big 3 getting in the “geo-web” business (we used to think of the big 3 as GM, Ford, and Chrysler—now its Google, Yahoo, and Microsoft) and bringing us to what I call “GeoWeb 2.0” applications, my kids can now relate to what I do all day at work. My wife still doesn’t grasp it—I still can’t get her to understand what I do, but my kids do now!!

The Evolution To Services Business Benefit 2000+ Web Services Service-Oriented Solutions Late 1990s Web technologies appear e.g., HTTP, HTML, XML Early 1990s Application integration technologies appear Pre-1990s Custom, static B2B Integration

What is a Service-Oriented Architecture? W3C: “A set of components which can be invoked, and whose interface descriptions can be published and discovered” BEA: “Service-Oriented Architecture is an IT strategy that organizes the discrete functions contained in enterprise applications into interoperable, standards-based services that can be combined and reused quickly to meet business needs.” Protegra: “A Services Oriented Architecture is an approach to system design where solutions are assembled from reusable component services.” A software component that is described via WSDL and is capable of being accessed via standard network protocols such as but not limited to SOAP over HTTP. A web technology with many, many TLA’s TLA = Three Letter Acronym

Key Concepts Reusable Components Loose Coupling

COM vs. Web Services Common Object Model (COM) Web Services Model DLL Common Object Model (COM)  Windows Operating System  Local Server operations  Scalability often requires custom application design  Proprietary communications  Native data types (fast)  Approaching end-of-life in favor of a Web Services model Web Services Model  Most Operating Systems  Local and remote Servers  Scalability requires off-the-shelf load balancing  XML communications  Data serialized into ASCII XML  A widely accepted and growing standard  An advantage  A disadvantage
