Best of this Week Summary 02 February - 08 February 2009

• In SOA lessons learned for Web 2.0 "two experienced SOA architects look at the new world of Web 2.0 technologies with a critical eye and present five best practices that can help you be more successful in adopting Ajax, REST, and other Web 2.0 technologies as part of your SOA."
  


• A quick comparison between Echo2 and GWT. Both enable you to create a rich internet application with only Java using a component-based approach. Wicket is also component based, but requires still to work with HTML; not necessarily a negative thing! For example, how will you split the work between the user interface designer and developers with Echo2 and GWT?
  


• A nice extensive summary of Model Driven Development misperceptions and challenges. Five challenges and five misconceptions in total.
  


• A whitepaper named "Centralized Service-Oriented Architectures without ESB" which shows how to create service-oriented architecture in a Google-like way, that is services around huge data repository, but without ESB. It is based on experience of the writers in data warehouses, Wiki and telecommunication systems. Thus, proposed is not really an ESB, but an architecture that's more like a centralised repository with distributed caching. Of course this comes with its own set of pros and cons, as mentioned in the whitepaper.
