While the hype rages around cloud computing, most cloud implementations go
the way of the private cloud and avoid the public clouds for now. Private
clouds are exactly what they sound like. Your own instance of SaaS, PaaS,
or IaaS that exists in your own data center, all tucked away, protected and
cozy. You own the hardware, you can hug your server.
However, what defines a private cloud these days could also mean systems that
are remotely hosted but dedicated to a single enterprise, and, in some cases,
provided out of a public cloud data center as a virtual private cloud. Thus
any cloud infrastructure that's dedicated to a single organization is getting
the "private cloud" label. This includes the emerging relabeling of
existing enterprise software and hardware solutions, looking to deliver
cloud-in-a-box private clouds.
If this sounds confusing, it is. The te... (more)
Many in the world of application integration have begun to adopt the notion
of ontology (or the instances of ontology: ontologies). Ontology is a term
borrowed from philosophy that refers to the science of describing the kinds
of entities in the world and how they are related.
Ontologies are important to application integration solutions because they
provide a shared and common understanding of data (and, in some cases,
services and processes) that exists within an application integration problem
domain, and how to facilitate communication between people and information
As we bring our SOAs online using Web Services, we all know that SOAP is the
standards message transfer protocol. But the interface description language
for Web Services (WSDL) isn't specifically for SOAP. It's more generic. A
SOAP-centric contract description language for Web Services is needed. Enter
the SOAP Service Description Language or SSDL. This framework was just
released in mid-February, and is now available for review. Let's take a look.
SSDL lets developers publish and share descriptions of the messages and
message exchange patterns supported by Web Services. It also a... (more)
I caught a review in Fast Company of an interview that Craig Newmark of
Craigslist had with ABC's Nightline News. I didn't see the interview myself,
but Fast Company did a good job highlighting the more important points,
including the fact that Craigslist, which offer free classified ads, is
killing the local newspapers.
"...There was the complaint that the site is hurting the newspaper business,
stealing away those who would buy classified ads. According to Nightline,
this shift has created an annual loss of $50 million in San Francisco alone."

Here we go again. While the paint is still wet on this new Web 2.0 stuff,
many SOA vendors and large analysts firms are calling their market SOA 2.0.
It's one of the silliest things I've heard in a long while, and both the
analysts and vendors who use this term should be ashamed of themselves.
I get Web 2.0 because the Web is well over 10-years-old and we've been
successful in using this pervasive technology and now we're moving to newer
and more exciting stuff such as AJAX and RSS thus the new version number.
However, we've yet to get large-scale traction with SOA so SOA 2.0 is ... (more)
