Projetos SOA

Falta de escalabilidade


Interview
John Crupi on Enterprise SOA

So service oriented architecture, hype or reality?

A little of both there's a lot of hype behind it. (...) it's
architectural driven and if
you don't have the architecture
in place there's no product that
out of the box will give you
SOA today.

Quest for True SOA
Posted by Alex Maclinovsky on Sep 10, 2008

According to these deﬁnitions, SOA
Governance is what turns Enterprise Services
from digital artifacts into true business
assets by allowing responsible reuse
across the domains of control of SOA
participants

SOA Governance: An Enterprise View
Posted by Michael Poulin on Aug 20, 2008 03:54 AM

(...)organisations were assured that SOA was new
IT technology for integration and reuse of
existing assets.


Article

Very few succeeded and went forward


Article

Other organisations failed in gaining
promised ROI and time to market


Interview
Jim Webber on quot;Guerilla SOAquot;

A lot of SOA projects I have seen, have been
somewhat akin to mobilizing an army.

We want to address speciﬁc discrete business
problems, organized by
priorities according
to the business stakeholder
and get those processes
implemented rapidly in an
incremental way with
feedback.
lots of

Major changes in
technology have
not been driven by
the technologies
themselves but by
the change in
thinking that
they enabled.


“Enterprises around the world are increasingly pursuing the
core business beneﬁts of Service-Oriented Architecture
(SOA)—business agility, reduction in integration expense,
greater asset reuse, and improved business visibility. And
yet, many large organizations are running into roadblocks
with their heavyweight, enterprise-wide SOA initiatives. As
an alternative, many organizations are ﬁnding a “right
weight,” step-by-step approach to SOA is more
effective and lowers risk as well.”

SIMPLIFYING SOA
LOW RISK, HIGH VALUE, “RIGHT WEIGHT” SOA
December 2007
Analyst: Jason Bloomberg

Economically,
quot;right-sourcingquot;
is far more eficient
than quot;outsourcingquot;
and SaaS.


Interview
Stefan Tilkov on SOA

Why SOA? Why now? What's
actually new?
(...) What I think is exciting is
the fact that it creates, or at
least that it is perceived to
create the opportunity to
align business and
technology.
