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... (more)
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)

Dan Woods provides an interesting analysis in Forbes, Parsing The Cloud, on
where Cloud Computing may be going next. He makes a good case that the cloud
will become more complex and diverse. He offers four drivers of this
diversity.
First, compliance is going to happen. Governments have already stepped in.
The Swiss banking laws dictate that computers storing customer information
must be housed inside its borders. Other countries may follow so they can
tax, inspect, or otherwise exert control.
Network topology will also affect the speed of data access. Different
industries have... (more)
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)
