I’ve been asked a number of times recently by industry peers and technology journalists about “virtualization” as it relates to SOA. Well, there are in fact at least 3 distinct ways that you can use virtualization concepts in SOA, so I think that it would be good for me to give you a definition of those three, and then in the next few days I will blog on each one of them independently. Rich Seeley recently interviewed me for a SearchWebServices.com article on the first and most often mentioned type of virtualization I’ll introduce -- which is hardware virtualization. This is not a SOA specific thing.  This is when you’re running many copies of the operating system within one physical hardware device so that you can get independence of those several virtual machines from each other -- from a configuration, app server and operating system...

New SOA Testing Survey from Aberdeen Group

We've been looking for some research to benchmark the maturity of SOA Testing efforts in isolation of SOA Governance as a whole. So when I heard Perry Donham was doing this over at Aberdeen, we wanted to participate in underwriting the survey and asking our users to contribute. "SOA and Web Services Testing: How Different Can It Be?" A free copy of the report is available here: http://www.aberdeen.com/link/sponsor.asp?spid=30410567&cid=4117 Of particular interest was less emphasis on component-level testing, and from 63% (average) to 81% (best in class) finding complete lifecycle tes...

Will SOA Fold into Cloud Computing?

I'm on my way to STARwest in Disneyland, CA today, and since it's been a little while since my last software quality-focused conference, I'm particularly interested to see how these testing experts and vendors are addressing the needs of a more distributed computing environment. Our own expert Rajeev Gupta is coming in to present "Building the SOA Quality Center of Excellence". Joe McKendrick recently posted, CTO Predicts SOA Will Fade into SaaS.  He quoted Ron Huxter, CTO of the provincial government of Ontario, “Over the last ten years, we’ve got most of the common business pra...

Agile SOA Across the Lifecycle - Part Five: IT and SOA Governance

This is the fifth of a six part series of posts on the Agile SOA life cycle. Here we will at look at IT and SOA Governance. With the introduction of agile, spiral, and scrum development methodologies, the traditional waterfall development approach of testing a near-finished app at the end of many Agile development cycles won't be agile at all, as the elements of the application are constantly changing.  Traditional models of IT governance will also not work. To aggravate testing, the service-oriented architecture (SOA) design pattern is used to make IT  more responsive to changes... (more)

Service-Oriented Virtualization - Can Virtual Environments Take Performance & Load Testing?

The iTKO SOA Testing, Validation & Virtualization Blog The practice and technology of Virtualization really has legs - it keeps moving forward, from hardware virtualization, virtual test beds, to virtual endpoints, to actually simulating the behavior of the software itself, which we're calling Service-Oriented Virtualization (or "SOV" if you need a TLA for it). Now we are seeing the Performance Lab getting into the action on this practice. For interconnected apps like SOA and serious enterprise integrations, the guys with the load testing firepower have tools like LoadRunner and ... (more)
