Many of the elements of Web 2.0 are highly relevant to service-oriented architecture and the service economy. In this post, I want to extract two sets in particular.
|Loosely coupled systems of systems||Small pieces loosely joined - web as components |
Granular addressibility of content
Software above the level of a single device
|User-centric||Users control their own data |
Rich user experience
Trust your users
Emergent - user behaviour not predetermined
Customer self-service - enabling the long tail
If we apply this kind of thinking to SOA, a distinction emerges between SOA 1.0 and SOA 2.0.
|SOA 1.0||SOA 2.0|
|Supply-side oriented ||Supply-demand collaboration|
|Straight-through processing ||Complex systems of systems |
|Aggregating otherwise inert systems and providing some new communication channels||Frameworks, applications, agents and communication channels understanding each other more deeply. Building a smarter stack and designing applications to take advantage of new constructs that (we hope) promote agility and simplicity.||Erik Johnson via Dion Hinchcliffe |
|Single directing mind ||Collaborative composition |
|Controlled reuse||Uncontrolled reuse ||See my earlier posts on Controlling Content and Shrinkwrap or Secondhand |
|Endo-interoperability (within single enterprise or closed collaborative system) ||Exo-interoperability ||I am currently preparing a longer paper on interoperability and risk. See my recent posts on Efficiency and Robustness. (1, 2) |
|Cost savings ||Improved user experience ||This is one of the areas where SOA starts to get interesting for the business and not just for the technologists. |
|An emerging network-centric platform to support distributed, collaborative and cumulative creation by its users||John Hagel |
There are some other elements of SOA 2.0 that I intend to discuss in subsequent posts.
