Tibco releases PageBus - Ajax publish/subscribe component
Not everybody is impressed though. Matt Asay said it is understandable for Tibco to do some open-source considering that Tibco's core products is threatened by open source vendors like Taled and MuleSource. Matt summed the issue by saying that
It's a good start for TIBCO, though shows that it's still guarding its crown jewels. Give it time.Anyway, in order to futher publicize the PageBus release, Tibco also announced a contest for building the "world's largest mashup" - provided off course that large mushup uses Tibco's components, and hey It actually offers some nice prizes...
Putting Tibco's publicity efforts aside, the notion of providing publish/subsribe communication infrastructure on the client side is actually important for mashups and service UI integration. When create a UI which integrates several services you are likely to get few unconnected "portlets" - each representing the service it interacts with. To make the UI more, well, integrated, the next step is to start doing some point-to-point integration between the otherwise disparate components. integration components like PageBus, allows you to connect UI component in a loosely coupled way and prevent the integration spaghetti. You can also find the similar functionality in other environment that allow Client/Service application (vs. the indirect integration of Client/Server/Service). For instance the Composite Application Block from Microsoft support a component called the Event-Broker which provides similar functionality for smart-client mashups. PageBus brings this functionality to the Rich Internet Applications (RIA) realm.
It would be interesting to see if Pagebus will be a popular choice in upcoming RIA based mashups or will some other product come dominate this niche.
