Enterprise Java Australia are holding a conference on the 17th of November in Melbourne, with keynote speeches on the Broadband initiative, Green IT, SOA, andGoogle Wave.  I will be facilitating one of the afternoon tech sessions on Cloud Computing.  If you're at the event, come and say hi to me. There's a 2 for 1 registration offer open until mid day on Friday.

Virtualisation is a pretty commonly known practice these days. IT operations staff use it as a method of consolidation and getting rid of old legacy hardware. Now we are being presented with virtualisation on demand facilities, usually referred to as Cloud Computing. This allows any user to create a virtual machine as a clone of a disk image at any time, use it for a while, and then throw it away.

This is a re-post of an earlier article I wrote. Any links to the old version will now be busted... Sorry. In our project, we follow a strict governance process for governing our services. We identify the services and their operations from our Business Process Model, then proceed to producing a WSDL and associated XSDs to represent that service. Only once this is done will we proceed to implementation. This is called top down design and is generally a good thing.

This is a re-post of an earlier article I wrote. Any links will now be busted... Sorry. UDDI registries provide a number of features. Primarily they are billed as governance mechanisms for enterprises running SOA environments. They also provide endpoint indirection capabilities, which are useful from a governance perspective, but can also be used for testing. This is an extension of the dependency injection pattern, which is commonly used in object oriented programming, into the distributed world.
