I've mentioned before how much work we've been doing in JBoss around the Cloud, both from an implementation perspective in our projects as well as thinking about where we need to go. Well today Red Hat is making more announcements around Cloud. This is much more than just PaaS though: we're announcing a strategy and technologies around the entire Cloud stack, called Cloud Foundations. As with everything we do though, standards and openness are critical, so this isn't yet another vendor lock-in strategy; we're working with a range of other vendors in Apache through Deltacloud, the DMTF and OASIS with Cloud-Identity. And I think it's pretty cool to think that Dreamworks will be using these technologies in the future (and my 8 year old son does too!)


To paraphrase the Rolling Stones, if you're thinking about Cloud now or in the future then "On my cloud baby"!  And maybe Mick should be singing "Hey you, get on to my Cloud"

Testable Architectures

Posted by Mark Little Aug 19, 2010

For several years we've been working with other industry experts on the WS-CDL specification as well as utilizing an implementation of the principles it represents. One way of thinking about what this work brings is that it turns the art of developing reliable and correct distributed systems into a science. As discussed a couple of years ago back on InfoQ, it can be likened to the industrialisation of IT. One of the principle co-authors of the CDL specification has written quite a bit about the benefits (often significant) of testable architecture to a range of clients he's been working for over the years. (There's even a pretty nice short video presentation.)


Originally this work was being done under the Overlord project, but about a year ago we decided that it made more sense to separate this out into a separate project, Savara. The aims remain the same, but the scope is no longer just SOA governance. Testable architecture (and WS-CDL) has a lot to say about workflow systems (choreographies, after all), and BPMN 2. In fact, I remain surprised and disappointed in equal measure that the other major players in SOA and BPM continue to push tools and methodologies that remain closer to black art than 21st Century science. However, this hasn't prevented a lot of people and companies being interested in what we're doing collaboratively. And the next major milestone has just been reached with the announcement of the first release of Savara! If you aren't monitoring this effort then you should be.
