Coupling is Like Pornography. "I shall not today
attempt further to define pornography...but I know it when I see
--Justice Potter Stewart, U.S. Supreme Court,
Jacobellis vs. Ohio, 1964
Loose coupling is like pornography. Everyone talks about it,
but when challenged, few can tell you what it is. For some, it
borders on a religion with the attendant fervor one would expect
from the newly converted. Others even go so far as to suggest
that the definition of loose coupling is itself loosely coupled,
providing them an excuse to avoid dealing with it. But with Loose
Coupling as the title of my forthcoming book, I'm not going
to get off quite so easily. Take a look at this table and let
me know what I've missed.

Perez published his own version, which included a number
of ideas I prefer to my own. And in email, Didier Girard suggested

McDowall, VP Engineering at Grand Central Communications,
has also taken a stab at defining loose coupling. I particularly
like his simple rule of thumb, "If the business consumer does

Hagel published his thoughts last month.
Helps with Applications on Demand. "IBM Global Services
will host the applications in its data centers and its software
partners will deliver them on-demand over the network to customers
using a variety of licensing models...The initial participants
in the program are software makers Adexa, Entrust, MRO Software
This is the Web Services Provider (WSP) model I discuss in my
forthcoming book. As Bob Hammond, CTO of Mirror-Image
Internet pointed out to me, it's actually great for software
publishers that are used to delivering software on CD-ROMs, but
have no experience with the 24x7 infrastructure required to deliver
software-as-service. [Source: The Web Host Industry Review]

Web Hosting Strategies
the Pain. In my latest column for The Web Host Industry
Review, I explain why it's often a better strategy to use
you web-hosting vendor's shared resrouces rather operate your
own servers, storage systems, routers, load balancers, backup/recovery
systems, and DNS and SMTP servers. This applies to large and small

Hosting to Die. Web Services to Drive Future. According
to the Meta Group, "By 2004, standalone business-focused web hosting
companies will cease to exist. As hosting prices rise 20 percent
to 25 percent in 2002 and 2003, a cross-functional team representing
IT groups, lines of business, and procurement organizations will
guide hosting purchase decisions. Web services will drive renewed
interest in outsourced extranets in 2003 and 2004, achieving operational
maturity by 2006.
"A fundamental understanding of Web services impacts on network infrastructure performance and capacity are being overlooked, setting the stage for yet another painful lesson to be relearned in much the same way enterprises and providers continue learning about application networkability."

Selling Open Source to Management . I'm a big fan of open
source and have successfully used open-source tools for some very
large systems. (I was VP Engineering at Organic Online where my
predecessors--Brian Behlendorf, now of CollabNet,
and Cliff Skolnick--spearheaded the early development of Apache.)
Here's a good article by Kevin Bedell on how to select open-source
technologies and how to convince the corner-office guys that they're
a good idea.

a Web Services Foundation: Web Services Strategies for IT Managers
December 10, 2:00 - 2:45am, Hotel Nikko, San Francisco (New Time!)
This session will drill down on the business and technical reasons
that are driving leading companies around the world to move away
from a vendor-specific legacy infrastructure and embrace a standards-based
Web Services architecture.
National studies of top IT managers indicate that when it comes
to assessing potential roadblocks to adopting Web Services, bandwidth
concerns are second only to security-related misgivings. This session
will provide the tools for accurately modeling the impact that moving
to a Web Services solution will have on your existing infrastructure.
Armed with this knowledge, you'll be ready to formulate a strategic
approach to developing and managing infrastructure resources that
can successfully support a scalable and dependable Web Services
