Web 2.0 For Dummies - part1: WOA

I presented in a conference of mixed audience: IT professionals and non IT professionals. The topic was: Web 2.0: The New Internet generation.

The presentation was an introductory: describing and experiencing by navigating through examples of Web 2.0 services and discussing their attributes and the cultural and technological differences between them and traditional IT companies and products as well as Web 1.0 services and product. As SOA is the major topic of this blog, I am discussing the links between SOA and Web 2.0 before posting the rest of the presentation. The main links between SOA and Web 2.0 are as follows:

  • Mashups and Services share the same vision: non-IT people assembling services for creating an application.
    The results are Reuse of these services, Agility and fewer resources in comparison to previous Application Development methods. It should be remembered that assembling Services in an Enterprise or Virtual Enterprise context requires robustness, control and management. These requirements are not part of the Social Context of Web 2.0.

  • Web 2.0 technologies are used as part of Enterprise SOA architecture
    Technologies like Ajax, REST and Wikis are used in enterprises including enterprises transforming their architecture to SOA. This usage is reflected in the SOA architecture.

  • End Users (Consumers and Service Assemblers) User Interface patterns used in SOA architecture should be the same patterns used in these users Social interactions which are changing gradually towards Web 2.0 Rich Internet Applications (RIA) patterns and User Interface. Therefore the SOA Enterprise includes the robust managed and governed Service side, which should be integrated with the user friendly, easy to build Consumer and Services Assemblers side. The integration is established by using middleware which should link between these two totally conceptually different components. This task is quiet difficult. Leading Integration infrastructure vendors and startup companies are in the beginning of development of these new middleware solutions.

  • Web 2.0 Services and Communities as a Distribution Channel
    SOA includes common Distribution Channel and End User devices architecture, enabling independence between the Consumer end and the Service. However, Web 2.0 communities are conceptually and technologically distinguished from other channels.
    Advertising and presenting SOA vendor technologies in Web 2.0 sites

  • Vendors develop Innovative concept of advertising SOA products and solutions in Web 2.0 communities.

SOA related slides appearing in my presentation are appended to this discussion. Next posts will include the other slides included in the presentation in sequential order. Each group will be appended to a discussion of its subtopic.
