Seven smart statements about SOA
[Michael Meehan, Site Editor]
A lot of people say a lot of smart stuff about service-oriented
architecture every week. It's amazing how much sober advice there is
out there. This week I thought I'd pool together some of the wiser
things I've read of late.
According to a recent column by analyst Judith Hurwitz: "While there
may be components that are different and innovative ? most services
are common across business units. Unique implementations of the same
services are simply that ? repetition based on aging business models
that simply have outlasted their usefulness."

In speaking about best practices for building an SOA business case,
Brad Shimmin of Current Analysis LLC said: "I would never even
mention SOA. I would build my business case without SOA. I'd build it
simply as a business case for the IT infrastructure that will either
make us money or save us money."

British Telecom chief architect George Glass offered up this
comforting bit of advice in a recent interview: "You can predict what
the level of performance will be. You can design the service with
that in mind."

In talking about SOA without Web services, Progress Software Corp.
CTO Hub Vandervoort said: "With most financial services firms,
especially in the front office trading environment and especially as
it relates to exchanges, you simply can't meet their performance
objectives with the WS-standards today. HTTP SOAP just isn't reliable
enough nor does it have the performance for the kind of traffic we're
talking about here."

Blogger and enterprise architect Mike Kavis laid how he sold his
employers on SOA, writing: "Once the business knew that SOA was the
enabler for their BPM initiative, which happened to have an eight
figure ROI over five years, they didn't need to hear anymore. They
only wanted to know how much!"
http://go.techtarget.com/r/2341856/6276287
During a Q&A, Sandy Carter, vice president for SOA and WebSphere
strategy at IBM, offered up this little bit of practical advice: "My
father always told me: 'Learn from someone else's mistakes, so you
don't have to go through those mistakes. It will make your life much
easier.'"
http://go.techtarget.com/r/2341857/6276287
In a discussion with Dana Gardner about SOA management, ZapThink's
Jason Bloomberg said: "As management technology improves, it is less
and less about just monitoring stuff, and more and more about being
able to deal with issues as a matter of policy, where your policy is
in place for dealing with problems that you can't predict - and those
are the most challenging ones.

How to Structure a Software Requirements Document
People learn better from examples than from descriptions or
templates. It's hard to find good public examples, since most
organizations view their requirements documents as proprietary. This

Grid Computing for Improved Application Development
Organizations often struggle to gain quick access to data, as
information is frequently distributed across multiple servers. This
reduces an organization?s overall application development efficiency,
as it is unable to analyze data quickly. This Techtalk details the
ability of grid technology to improve data availability, enabling
real-time analysis and more effective application development.

The convergence of service orientation and business strategy
Where the core competency model focuses on doing things more
efficiently than market rivals, a differentiation-based strategy
focuses on doing things differently (or doing different things) than
market rivals. In this article, we will expand our discussion beyond
the core competency model to explore differentiation-based strategy,
and consider the linkage between an organization's strategic posture,
and its approach to service-orientation.
