FYI -
I
wasn't aware of consternation between SOA and Web 2.0. I just think of
open API mash-ups as SOA-lite.

SOA Versus Web 2.0?
As I indicated in my previous posting, a cultural
chasm separates these two
technology communities, despite the fact that they
both rely heavily on the
same foundational standard - XML. The evangelists
for SOA tend to dismiss
Web 2.0 technologies as light-weight
"toys" not suitable for the "real" work
of enterprises. The champions of Web 2.0
technologies, on the other hand,
make fun of the "bloated" standards and
architectural drawings generated by
enterprise architects, skeptically asking whether
SOAs will ever do real
work.
Both Web 2.0 and SOA technologies re-conceive
software as services. Perhaps
even more importantly, they view services as
platforms. Rather than viewing
services as standalone offers designed to be
consumed exactly as written,
both sets of technologies start with the vision
that the role of any service
is ultimately to become the building block for
even more services that will
be built on top of the original service.
Amazon provides an early, and very limited,
example of this opportunity. By
developing an affiliate program and offering a
book buying service that can
be embedded into other web sites, Amazon has been
able to significantly
expand its reach and create a much more robust
platform for driving
e-commerce activity.
The growing appeal of Web 2.0 technologies in part
stems from this hijacking
of SOAs. Line executives within the
enterprise are experiencing mounting
frustration over the escalating hype around SOAs,
the growing spending over
SOA design initiatives and the relatively limited
business impact achieved
by SOA deployments. In contrast, Web 2.0
initiatives are leading to a
proliferation of mashups (one form of composition),
as described by Dion
Hinchcliffe in "The Web 2.0 Mashup Ecosystem
Ramps Up" and "Some Predictions
for the Coming 'Mashosphere' "
Does this mean SOAs are DOA? Not at all.
SOAs still provide a valuable
foundation to support the sustained relationships required
for distributed
creation. But these SOAs need to be deployed
in a much more incremental and
pragmatic way. Perhaps a little competition
from Web 2.0 technologies will
help to break the logjam and force both IT
departments and IT consultants to
adapt their culture and operations to growing
business pressure for
accelerated impact and learning.
As JSB and I discuss in much more detail in The
Only Sustainable Edge, the
convergence of SOAs, virtualization architectures
and Web 2.0 social
software will drive the next wave of value
creation within and across
enterprises. The convergence will not unfold
smoothly, as much of the
current debate confirms, but it will take place -
there is too much at stake
and each of these technology arenas offers something
distinctive in
supporting next generation business platforms.
