Architecture in Turbulent Times

Letter from the Editor

Dear Architect,

Let's start with the basics: the goal of our Architect role is to align IT with the course of business. So far, so good, eh? So, being that almost every business has been challenged as a consequence of the current economic slowdown, we-as architects-are challenged to make our architectures follow the pace of business that these days is particularly changeable and unstable.

We thought that we had a clear understanding of the rules corresponding to the latest scenario. Having made a plan to face it, and being in the middle of the execution, we're told that the organization must now implement further changes to keep business going. The results of the last quarter were known, and growth expectations were revised to lower-perhaps negative-numbers.

This issue of The Architecture Journal won't tell you when this meltdown will end or whether we'll have kept our jobs. It will, however, share architecture strategies, IT behaviors, and-for sure-success stories. I counted on the invaluable collaboration of Mike Walker as guest editor for this issue. Mike wrote the opening article, which details how architects can add value back to the business during climates as particular as the current one. He and the other authors are architects like you and me: they didn't live during the Great Depression and, even if they had, technology in general and IT architecture as a discipline were slightly different from what they are today. They were suddenly challenged, and they responded to those challenges. Now, they tell us how they are succeeding. I hope you'll find both inspiration and courage in these pages.

By the way, as announced in the last issue, we keep adding features to the Journal to take advantage of its now mainstream digital format. We've introduced a "Follow Up" section at the end of any article that has references for going further with implementation.

This issue, we're introducing the "guest columnist" concept. You'll find that an article comes with one, two, or even three guest columnists. We intend to widen coverage on a given topic by offering different perspectives and voices. We're not yet done with these new features. Also, for those of you who are interested in receiving a printed version, we're still working on a print on-demand model.

By chance, are you interested in writing an article for the Journal? We just finished a call for papers on "SOA at the end of the decade," and we thank all of you who participated in that call. You can learn about a future call for papers by subscribing to The Architecture Journal newsletter, which you can do by visiting The Architecture Journal Web site.

As always, you can let us know your opinions directly by e-mailing us.

SOA Call for Papers

May 2009

SOA Keys for Success

Call for Papers

The 21st issue of the Architecture Journal will be devoted to SOA Keys for Success.

While Cloud, Utility, and Green Computing trends emerge as probable candidates for the top of the enterprise IT agenda for the next decade, SOA undoubtedly has been the priority during this decade, and particularly during these five last years.

The initial appeal of SOA came when the industry acknowledged how standards such as XML Web Services easily achieved decoupled levels of integration that were unseen on previous, complex attempts such as CORBA or COM.

Then came the SOA rush, and a growing number of companies embarked on SOA projects while Web Services standards continued to evolve in order to close the gap in security, reliable messaging, and transactional integrity.

Some years later, we can confirm that SOA has accomplished its promise of interoperability. But where SOA practitioners probably will disagree is on the total cost of ownership of this kind of project. We might find as many successful stories (on time, on budget, and straightforward) as not-so-successful stories (more expensive than projected, unforeseeable complexity, and so on).

What are the factors that make the difference? We are calling for articles on:

. SOA practices. Which ones determine the success-or failure-of a project?
. SOA governance. Running, monitoring, versioning: How better to serve services?
. To ESB or not to ESB. Angel or demon? When to consider it a fundamental piece? What about it should you get rid of?
. From object to services. Considerations to guarantee separation of concerns after shifting paradigms.
. Enhanced SOA. How alternative, complementary approaches such as Event-Driven Architecture (EDA), REST protocols, service virtualization, and others are helping SOA traverse the last mile of integration.
. SOA and The Cloud. What SaaS, S+S, and related emerging delivery models have to offer to an in-house SOA investment.

If you have ideas on these topics that you would like to share with the architecture community, this is your chance! To submit an idea for an article, please send the following before June 11, 2009:

. An abstract of between two and four paragraphs that explains what the reader will get from your article with regard to the "SOA Keys for Success" theme of the issue. If you like, you may submit on an alternative topic; we have published out-of-theme articles in the past. However, your chances of being selected might be lower.
. A bio of between one and two paragraphs.
. A list of your previously published articles, if any.

Submissions should be made via e-mail to archjrnl@microsoft.com (we receive many submissions for each issue, so we encourage you to put time and thought into your submission).

After the call for articles has ended, everyone who has submitted an idea will be notified via e-mail as to whether their submission was successful or not. If it is accepted, your article must follow this schedule:

. June 17. Acceptance notified.
. July 8. First draft (possibly unfinished) is due.
. July 22. Final draft is due.*
. September 5. Your article and the Journal are ready and published.

* We recommend that articles be between 2,500 and 3,500 words in length. We will ask you to sign a release form that gives Microsoft permission to reprint the article, although ownership of the article will remain with you.

Computer Sciences and Consciousness: Journal on Sustainable Computing Just Released

diegumzone — Fri, 19 Dec 2008 05:01:00 GMT

The theme of this issue, “Green Computing,” is especially important and timely: As computing becomes increasingly pervasive, the energy consumption attributable to computing is climbing, despite the clarion call to action to reduce consumption and reverse greenhouse effects. At the same time, the rising cost of energy — due to regulatory measures enforcing a “true cost” of energy coupled with scarcity as finite natural resources are rapidly being diminished — is refocusing IT leaders on efficiency and total cost of ownership, particularly in the context of the world-wide financial crisis.

We are pleased to have Lewis Curtis, Principal Architect on the Microsoft Platform Architecture Team, as our subject matter expert on this topic and co-editor for this issue. In the first article (page 2), Lewis provides a holistic approach to greener architectures, and he also helped us subdivide the topic in five perspectives:

• Physical. The Genome research project, described in “Wireless Sensor Network for Data Center Monitoring” (page 28), uses heat distribution data from a wireless sensor network to optimize data center design and server provisioning in order to avoid overcooling the entire data center.
• Operating Platform. Hardware resources are often allocated based on a worst-case scenario that may happen with a low frequency. As a result, complete farms may be as much as 90 percent underutilized. Read Mark Pohto’s article on SQL Server consolidation (page 35) to learn more about virtualization and other consolidation tactics.
• Sustainable Intelligence. An Energy Usage Profile (EUP) is an essential tool for measuring energy consumption in various domains such as hardware, operating systems, users, and applications, as the Software Architect of the Future explains in the article by Steve Stevanovich and coauthors (page 24).
• Application Development. Solution architects also have an opportunity here, as coauthors Dan Rogers and Ulrich Homann point out in “Application Patterns for Green IT” (page 16). Green computing discussions today tend to focus on the platform, hardware, and data centers. However, application inefficiencies, such as suboptimal algorithms and inefficient usage of shared resources causing contentions, are originators of higher CPU usage and, therefore, energy consumption.
• The Cloud. In their article on virtualization maturity model (page 9), Kevin Francis and Peter Richardson also cover utility computing-based delivery models. Insofar as this these models consolidate organizations, consumption has the potential to be remarkably reduced as the Internet scale data centers in which services are hosted can make efficient use of shared resources (servers, storage, cooling mechanisms, and so forth).

Now and in the future, green computing will be a key challenge for businesses and presents a leadership opportunity for all architects. It is an exciting time to
be an architect. Celebrating the relaunch of the Architect MVP (Most Valuable Professional) program, we interviewed Udi Dahan (Architect MVP for four years
now) in our Architecture Journal Profile (page 22).

We hope you enjoy these thoughtful articles on green computing. We invite you to visit the Microsoft Environmental Sustainability portal at http://www.microsoft.com/environment/, and as always, we welcome your feedback at editors@architecturejournal.net.

Just Released: Architecture Journal 16 on Identity and Access

diegumzone — Fri, 22 Aug 2008 19:08:00 GMT

Two years ago, when an article of mine about evolving architectures was published in an independent IT magazine, a colleague said to me, “You should write for The Architecture Journal.” I couldn’t have predicted that I would now find myself writing for this magazine as its editor. I want to thank Simon Guest for this opportunity and these big shoes to fill; during his tenure, readership has more than doubled, increasing from 30,000 to 62,000+.

In this issue, we invite you to think about the identity architecture in your organization. Identity management today is evolving from the single, isolated scenario to a federated one, in ways that might surprise you.

We begin this sixteenth journey with Fernando Gebara Filho’s introduction to identity concepts and strategies, how they have evolved and the road ahead. Next, Jesus Rodriguez and Joe Klug examine an assortment of strategies for making identity a first-class citizen in the portfolio of federated applications. Gerrit van der Geest and Carmen de Ruijter Korver consider the challenge of establishing an application-level trust environment, as user identities, in a service-oriented world, must flow from a service consumer to a provider.

For this issue’s profile, we caught up with Kim Cameron, author of “The Laws of Identity,” whose ideas on federated identities are shaping the next generation of Microsoft identity technologies. (A funny thing happened the day I visited Kim for this interview: I forgot my ID badge, so I needed Kim to “certify” my identity to the lobby.)

Resuming our journey, Mario Szpuszta describes how the Austrian healthcare system turned an administrative provisioning crisis into a clear opportunity for creating an open identity federation. Then Vittorio Bertocci explains how architectural patterns allow us to build claim-aware solutions, so that when the cloud arrives to companies, identity management won’t necessarily look cloudy.

Finally, Mike Morley and Barry Lawrence reveal how they synchronized identities on multiple systems and legacy applications from a single administrative console through a consolidating framework.

Dear reader, I’d like to be the first to welcome you to the issue, and hope that you’ll identify with the articles within. Enjoy!

David Chou offers a comprehensive view of strong user authentication by examining its concepts, implementation approaches, and challenges and additional concerns
