It is the infrastructural paradigm shift that is sweeping across the Enterprise IT world, but how is it best defined? I refer of course to 'Cloud Computing' - the phenomenon that currently has as many definitions as there are squares on a chess-board. To try and narrow it down we bring here a round-up of some recent attempts to bring welcome precision where there risks being unnecessary vagueness. Enjoy!

This document analyzes how design decisions of a specification's conformance model may affect its implementability and the interoperability of its implementations. To do so, it introduces the concept of variability - how much implementations conforming to a given specification may vary among themselves - and presents a set of well-known dimensions of variability. Its goal is to raise awareness of the potential cost that some benign-looking decisions may have on interoperability and to provide guidance on how to avoid these pitfalls by better understanding the mechanisms induced by variability.

For many years, Java and web developers alike have had to explain to the unwitting that JavaScript had absolutely nothing to do with Java. It was one of the great marketing gaffes of the mid-90s. They were no more alike than chalk and cheese. But in the last six months, I've had to lay down my placard and walk away from the picket line with a smile on my face and a skip in my step. Finally Java has been put into JavaScript.

Members Approve Web Services for Remote Portlets (WSRP) 2.0 as OASIS Standard IBM, Sun Microsystems, Microsoft, Novell, Oracle, SAP, TIBCO, Vignette and Others Collaborate on Open Standard for Integrating Web Services into Portals

Boston, MA, USA; 30 May 2008 — OASIS, the international open standards consortium, today announced that its members have approved the Web Services for Remote Portlets (WSRP) version 2.0 as an OASIS Standard, a status that signifies the highest level of ratification. Developed through an open process by the OASIS WSRP Technical Committee, the new standard simplifies the effort required for aggregating applications, such as portals, to quickly integrate remote content and applications. "Vendors of aggregating applications no longer need to write special adapters to accommodate the variety of interfaces and protocols used by content providers," explained Rich Thompson of IBM, chair of the OASIS WSRP Technical Committee. "With WSRP, they can integrate remote content and applications with just a few mouse clicks and virtually no programming effort. WSRP version 2.0 adds those capabilities needed to fully integrate the remote components into the aggregated application."
