Architecture and change: The proper end is fitness for purpose

T
he enterprise transformation theme of The Open Group’s San Francisco conference reminded me of the common assertion that architecture is about change, and the implication that enterprise architecture is thus about enterprise transformation.

We have to be careful that we don’t make change an end in itself. We have to remember that change is a means to the end of getting something we want that is different from what we have. In the enterprise context, that something has been labeled in different ways. One is “alignment,” specifically “business/IT alignment.” Some have concluded that alignment isn’t quite the right idea, and it’s really “integration” we are pursuing. Others have suggested that “coherency” is a better characterization of what we want.

I think all of these are still just means to an end, and that end is fitness for purpose. The pragmatist in me says I don’t really care if all the parts of a system are “aligned” or “integrated” or “coherent,” as long as that system is fit for purpose, i.e., does what it’s supposed to do. [Disclosure: The Open Group is a sponsor of BriefingsDirect podcasts.]

I think all of these are still just means to an end, and that end is fitness for purpose.



I’m sure some will argue that alignment and integration and coherency ensure that a system is “optimal” or “efficient,” but doing the wrong thing optimally or efficiently isn’t what we want systems to do. It’s easy to imagine a system that is aligned, integrated and coherent but still not fit for purpose, and it’s just as easy to imagine a system that is not aligned, not integrated and not coherent but that is fit for purpose.

Of course, we can insist that alignment, integration and coherency be with respect to a system’s purpose, but if that’s the case, why don’t we say so directly? Why use words that strongly suggest internal properties of the system, rather than its relationship to an external purpose?

Value is in implementation


W
hatever we call it, continuous pursuit of something is ultimately the continuous failure to achieve it. It isn’t the chase that matters, it’s the catch. While I am sympathetic to the idea that there is intrinsic value in “doing architecture,” the real value is in the resulting architecture and its implementation. Until we actually implement the architecture, we can only answer the question, “Are we there yet?” with, “No, not yet.”

Let me be clear that I’m not arguing, or even assuming, that things don’t change and we don’t need to cope with change. Of course they do, and of course we do. But we should take a cue from rock climbers -- the ones who don’t fall generally follow the principle “only move one limb at a time, from a secure position.”

What stakeholders mean by fitness for purpose must be periodically revisited and revised. It’s fashionable to say “Enterprise architecture is a journey, not a destination,” and this is reflected in definitions of enterprise architecture that refer to it as a “continuous process.” However, the fact is that journey has to pass through specific waypoints. There may be no final destination, but there is always a next destination.

There may be no final destination, but there is always a next destination.



Finally, we should not forget that while the pursuit of fitness for purpose may require that some things change; it may also require that some things not change. We risk losing this insight if we conclude that the primary purpose of architecture is to enable change. The primary purpose of architecture is to ensure fitness for purpose.

For a fuller treatment of the connection between architecture and fitness for purpose, see my presentations to The Open Group Conferences in Boston, July 2010, “What ‘Architecture’ in ‘Enterprise Architecture’ Ought to Mean,” and Amsterdam, October 2010, “Deriving Execution from Strategy: Architecture and the Enterprise.”

HP's Gen8 servers attack data center woes head on with better management, automation, and energy conservation to cut total costs

HP today took direct aim at the ever-increasing costs of data centers and managing an explosion of data by announcing a new generation of automated and efficient hardware. The new generation of ProLiant servers includes better internal management, powerful automation features, and improved energy conservation.

The ProLiant Gen8 servers are part HP's Converged Infrastructure strategy, and represent the first step in the company's Project Voyager, a two-year, $300-million effort to redefine the economics of the data center. At the heart of the new generation of servers is ProActive Insight architecture, which includes integrated lifecycle automation, dynamic workload acceleration, automated energy optimization, and proactive service and support. [Disclosure: HP is a sponsor of BriefingsDirect podcasts.]

Data has become a differentiator in business, and with an ever-expanding growth in storage needs, enterprises are feeling the pinch in personnel costs, energy, and facilities. Supporting data as a lifecycle may be IT's fastest growing cost worldwide.

Analysts now predict a 45 percent annual increase in storage over the next three years, and the current annual costs associated with storage are estimated at $157 billion. In addition, server administration and operations cost three times the price of servers, while the cost of facilities to accommodate the data center is even higher.

“The skyrocketing cost of operations in the data center is unsustainable, and enterprises are looking to HP to help solve this problem,” said Mark Potter, senior vice president and general manager, Industry standard Servers and Software, HP. “We are delivering innovative intelligence technologies that enable servers to virtually take care of themselves, allowing data center staff to devote more time to business innovation.”

Integrated lifecycle management


I
ncorporating three major innovations, Integrated Lifecycle Automation simplifies common tasks to keep systems running at peak performance, with an estimated 93 percent less downtime during updates than with previous generations, said HP. These innovations include:
  • Intelligent Provisioning, which enables organizations to get systems online three times faster with a fully integrated server and operating system configuration tool.

    Intelligent Provisioning enables organizations to get systems online three times faster with a fully integrated server and operating system configuration tool.


  • Active Health system, which allows administrators to collect troubleshooting information five times faster by continuously monitoring more than 1,600 system parameters and securely logging all configuration changes.
  • Smart Update, a system maintenance tool that systematically updates servers and blade infrastructures at the scale of the data center.
Dynamic workload acceleration

The demand for data-intensive and transactional workloads such as data warehousing, real-time analytics, and virtualized environments is expanding dramatically. These workloads bring unpredictability to the data center requiring a fundamental change in the way compute and storage services integrate.

HP's Gen8 servers aim to reduce and in some cases eliminate bottlenecks by converging compute and storage services through three innovations:
  • Solid-state optimization, delivering what HP says is a 500 percent improved storage performance using SSDs that reduces costs and downtime over previous generations, and promises two times more storage per server.

    Intelligent performance analytics continuously optimize system performance and efficiency in real time.

  • Real-time data protection, adding multiple embedded data protection technologies such as Advanced Data Mirroring, which HP says is 1,000 times safer than traditional two-drive mirroring in previous generations, while improving read performance.
  • Intelligent performance analytics that continuously optimize system performance and efficiency in real time, with the ability to analyze a variety of workload-specific data points.
Automated energy optimization

E
nsuring that data center capacity will meet growing workload requirements is critical. However, constraints on physical space, rising power demands, and limits on available cooling are adversely affecting data center capacity. In many organizations IT managers are struggling to get what they need from existing resources without inadvertently causing downtime.

The Gen8 servers enable data center and IT managers to identify the physical location of each server in the rack, row and data center. This insight, combined with a sea of intelligent sensors embedded into each server, allows users to reduce power requirements, reclaim as much as 10 percent more usable power per circuit and eliminate manual configuration and tracking errors that can increase downtime.

The Gen8 servers enable data center and IT managers to identify the physical location of each server in the rack, row and data center.



Three new features automate energy optimization in the data center so users can:
  • Optimize workload placement with Location Discovery Services and eliminate labor-intensive and error-prone tracking of IT assets
  • Reduce energy use and increase power capacity with Thermal Discovery Services, which improve airflow efficiency by as much as 25 percent with an intelligent server rack meaning that enterprises can realize an estimated energy saving of $2,750 per 10kW rack
  • Increase system uptime with Power Discovery Services, which automatically track power usage per rack and server, eliminating errors and manual record keeping to reduce unplanned data center outages
Partner program

HP says the new servers will also be a boon to participants in the Partner Program, because partners can expand their service portfolio, increase partner touchpoints, enhance remote technical capabilities, and create consultative opportunities over the life of the customer’s solution.

Further, by eliminating manual processes and the potential of human error, HP and channel partners can reduce outages, while focusing IT resources on strategic tasks. Specifically, partners can:
  • Deploy servers seven times faster over competing servers with automation and elimination of software downloads and CD installations.

    The skyrocketing cost of operations in the data center is unsustainable, and enterprises are looking to HP to help solve this problem.


  • Reduce downtime by automating processes for updates, application provisioning, patch management, and other maintenance tasks.
  • Improve issue resolution with a 95 percent "first-time fix" rate and 40 percent reduction in problem resolution through Insight Online, Active Health, and Insight Remote Support, which automatically pinpoint, diagnose and often proactively fix issues.
ProLiant Gen8 servers are available to early-adopter clients today. General availability begins in March and continues throughout 2012. This includes ProLiant ML tower servers for remote and branch offices and versatile ProLiant DL rack-mount servers that deliver a balance of efficiency and performance. Also included are ProLiant BL blade servers for cloud-ready Converged Infrastructure and ProLiant SL scalable system servers built for web, cloud and massively scaled environments.
