According to Moore's Law , processing speed and storage capacity have been
doubling about every two years since the invention of the integrated circuit
Yet it seems that our propensity for building larger more complex software
systems that anticipate these improvements inevitably outpace the exponential
growth in capacity to support these systems. SOA is becoming more broadly
adopted, along with the practice of using XML as a means of communicating
data between services and the more rapid adoption of applications to Internet
scale. Staring you in the face of your application's success, the potential
to overwhelm your systems has become very real, and may happen at times when
you least expect it.
How do we get ahead of this trend? Given that memory and storage are always
increasing in the realm of enterprise computing, software needs to keep up
with the... (more)
Applications are increasingly being developed "built-to-integrate," providing
the ability to easily expose key functionality through commonly defined
interfaces. Gartner calls this concept SODA, or Service-Oriented Development
of Applications, fitting into its overall Service-Oriented Architecture
landscape. When applied to the ever-present integration challenge, SODA
represents a transition to service-oriented integration.
In this presentation, Chappell will examine the leading choices for
supporting service-oriented integration: enterprise service buses (ESBs),
integration ... (more)
(January 14, 2003) - On Thursday January 9, Sonic Software and a number of
other leading IT vendors, including Fujitsu Limited, Hitachi, Ltd., NEC Corp,
Oracle Corp., and Sun Microsystems, announced a proposal for a new Web
services specification for reliable messaging: Web Services Reliability
(WS-Reliability). The companies plan to submit WS-Reliability to a standards
body on a royalty-free basis in the near future.
Along with security, reliable asynchronous communications has been one of the
gaping holes in today's Web services architecture. Lack of reliability, due
to the inh... (more)
I recently attended the WS-ReliableMessaging Interop fest, hosted by IBM.
IBM has published the results. The publishing of the results is something
that the legal agreement allows the spec authors to do. A public version of
the legal agreement and the test scenario document can be found here.
The interop participants included -
BEA Systems, Inc
Blue Titan Software, Inc.
NEC Laboratories America, Inc.
Sonic Software Corporation
TIBCO Software, Inc.
The results, as written in the public report, exceeded expectations. We
actually finish... (more)
Since releasing my latest book, Enterprise Service Bus (O'Reilly Media,
2004), I have been doing a fair amount of visiting corporations, conducting
seminars, and generally discussing with enterprise architects the subject of
enterprise service-oriented architecture (SOA) and how an enterprise service
bus (ESB) backbone can be leveraged to provide a framework for an enterprise
SOA. Along the way, I have been asked many questions about the nature of an
ESB. I have also fended off some misconceptions that have been growing in the
general IT population regarding what an ESB is and wh... (more)
