According to the Burton
Group, the issues around
SOA are not so much about
technology and complexity
as they are about the
people and the processes
within an enterprise.
Indeed, in a recent
article by Jon Brodkin,
some of these issues are
highlighted. The core
iss...
It's important to
remember that there is a
huge resource being
created on the Web these
days in terms of both
services and content.
This includes access to
SaaS applications (that
are better than their
enterprise-bound
counterparts), service
marketplaces, and even...
It doesn't take a rocket
scientist to understand
that mashups are moving
from things that are
conceptual and fun, to
things that are
productive and
businesslike. The fact
is, developers are
leveraging mashups to
solve all sorts of
business problems these
days, a...
It's what you don't see
about the emerging Web
that has everyone excited
these days. Namely, it's
the powerful application
programming interfaces,
or APIs. APIs are nothing
new and have been
traditionally cryptic and
difficult to use.
However, the advent of
Web se...
If you read this column
and listen to my
podcasts, you know that I
call SOA what SOA is - an
architectural pattern. In
many instances, SOA is a
vital component of
healthy enterprise
architecture. Indeed,
I've provided some
keynote talks around this
very topic at a...
As I've been stating for
the past five years: if
you want to provide real
value to your enterprise,
SOA should extend out of
the firewall and into the
Internet. However, this
was not universally
accepted by the
rank-and-file SOA guys.
Generally speaking, most
view...
I get these about once a
week: an e-mail from a
Yahoo or Google e-mail
account that talks about
issues within a large
enterprise that are
related to building their
first instance of SOA.
The fact is that most of
these e-mails are not
around proper approaches
or th...
Many SOA projects are
created out of hype, not
need. Clearly many
enterprises are 'managing
by magazine' and are more
concerned about doing
something cool rather
than doing something
helpful. You know the
difference, and I'm sure
there are both types of
projects i...
Architectures are like
archaeology; in essence,
layers upon layers of
systems, applications,
databases, and
connections, typically
built or procured to
solve a tactical problem.
Many corporations talk a
good game and brag about
the strategic long-term
direction of...
While few will disagree
that the inefficiencies
of existing enterprise
architectures have
reached a critical level,
many count on 'flying
under the radar' of those
who look at a company's
efficiencies. Let's face
it; enterprise
architecture is very
technical and d...
Last month I wrote about
vendor-driven
architectures (VDA), and
I had a few vendors ask
me to look on the other
side of the fence. In
essence, to consider how
vendors can better
address the needs of the
customer, considering the
new drivers with SOA.
Truth be told...
When looking at
technology buying
patterns in the world of
SOA, there's one common
thread. The Global 2000,
and many government
agencies, are purchasing
from their existing
vendors, no matter what
the needs or
requirements. I call
these solutions
purchasing 'com...
With the advent of Web
services and SOA, we've
been seeking to create
architectures and systems
that are more loosely
coupled. Loosely coupled
systems provide many
advantages including
support for late or
dynamically binding to
other components while
running, and ...
To mark a new standard in
the SOA space, I create a
Google Alert and sift
through the pile of links
returned to get the scope
of its maturation. I'm
currently tracking over
60 standards, starting
with SOAP and XML (XML
happened way before
Google was cool).
So, does testing change
with SOA? You bet it
does. Unless you're
willing to act now, you
may find yourself behind
the curve as SOA becomes
systemic to all that is
enterprise architecture,
and we add more
complexity to get to an
agile and reusable state.
Making solutions scale is
nothing new. However, the
SOA technology and
approaches employed
recently are largely
untested with higher
application and
information and service
management traffic loads.
SOA implementers are
happy just to get their
solutions up and run...
If you've kept up with
SaaS and SOA you know
that Salesforce.com does
an on-demand SOA
solution. Apex is its
on-demand development and
deployment platform,
including a complete
development environment,
programming language,
database, and now the
ability to create,...
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
sh...
While the notion of SOA
continues to emerge,
those who are
implementing SOAs today
are faced with a variety
of challenges, including
the complexities of SOA,
and the work involved
with understanding their
existing problem domain
and requirements. Those
who want to...
This is the larger issue,
as I see it, and is very
visible to me working
both in the world of SOA
and the world of
enterprise architecture.
So, why are they
different worlds?
Moreover, what is
enterprise architecture,
and how does it fit with
reference models and ...
The SOA reference
architecture (RA)
provides a bridge between
the concepts and
vocabulary defined by the
SOA Reference model and
the implementation of a
SOA. The SOA reference
architecture models the
abstract architectural
elements for a SOA
independent of the
t...
I spent a few hours of my
weekend attempting to
research and define these
concepts a bit better, in
essence, taking
everyone's opinions and
normalizing them so they
make better sense. What I
found were many of the
same notions, defined
differently, but all
attempt...
First, the history. Data
integration is the name
the vendors have adopted
to replace the ETL
(Extract Translate Load),
data cleansing, and data
warehousing tools of days
gone by. These tools
actually pre-date the
notion of EAI, and were
really the first sets of
te...
I'm consulting now...at
the project and strategy
levels...and finding that
a lot of real work needs
to be done to get SOAs up
and running. For most
organizations, the first
step of their SOA project
is to figure out how much
this SOA will cost. So
you can budget
a...
A few of my clients are
now looking to staff
their first inroads into
SOA, their first project
where something actually
happens beyond the
investigation. So...how
many people are needed on
the project? Who are
they? What are their
roles? Here are some
rough guidel...
Working directly on SOA
projects as an
independent I'm exposed
to many more
organizations than when I
was building technology.
As such, I see some
common patterns or issues
emerging. The largest and
most disturbing is the
fact that there seems to
be a huge chasm y...
Last month an alliance of
leading vendors announced
progress on
specifications to define
a language-neutral
programming model for
application development
in SOA environments. They
call this specification
Open SOA Collaboration.
In essence, they are
proposing a new...
Right now the
implementation of SOAs
seems involve much more
hype than actual work.
However, there are some
patterns beginning to
emerge, or, procedures
the implementers are
doing right to insure
success. These patterns
are not always obvious,
so perhaps this is a...
Let's face it, WS-BPEL
1.1 was not a great
standard, and left so
much out that many end
users and vendors found
it useless. In response,
the vendors put a ton of
proprietary extensions in
their BPEL 1.1-based
products, thus diluting
its value to the point of
'Why ...
What is unique about an
SOA is that it's as much
of a strategy as a set of
technologies, and it's
really more of a journey
than a destination.
Moreover, it's a notion
that is dependent upon
specific technologies or
standards, such as Web
services and interface
tec...
So what's hot these days
in the world of SOA?
Governance, registries,
orchestration...? Nope.
As folks looking to
implement SOA seek that
first killer project the
emphasis is on what to
do, not what you use, and
that's exactly the right
way to think. As SOA
become...
It has come to my
attention that there are
really two kinds of SOA
technology vendors out
there, old school and new
school - each offering
very different approaches
to solving the SOA
problem. I'm not going to
mention any particular
vendors, but you guys can
guess who they are.
There is a lot of talk
about how SOA will
significantly lower the
need for developers, thus
the savings of SOA. This
will be accomplished
through the promise of
reuse that's driving many
toward the SOA light.
However, I'm not sure
we'll see a reduction in
developm...
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 off...
The notion of building
bridges to service
providers and managing
the interaction will
become more commonplace
in 2006 as we learn to
accept that many services
we leverage within an
enterprise are services
we may not host. The
technology exists today.
We need to de...
