XML-empowered documents extend SOA’s connection to people and processes

Read a full transcript. Listen to the podcast. Sponsor: JustSystems North America.

Services Oriented Architecture (SOA) should dramatically improve the relationship between people, processes, and IT. Yet the potential for SOA remains clouded due to a gulf between worker knowledge and the new services automation benefits, which remain focused on structured data and existing applications.

New advances in documents-based technology, management, and dynamic content enrichment offer a promising lifeline to help solve SOA’s tenuous relationship to people and task-oriented knowledge. For example, the Darwin Information Typing Architecture (DITA) Maturity Model, co-authored between JustSystems and IBM, offers a standardized approach for technical document authoring and publishing.

We're seeing these two areas -- SOA and newly dynamic documents -- come together. Structured documents and the lifecycle around structured authoring tools provide an end-point for the assets and resources managed through an SOA. But we're also providing a two-way street, where the information and data that comes in through end-users can be reused back in the SOA to combine with other assets for business process benefits.

Our friends at ZapThink recently developed a report and webinar on many of these trends and benefits, as well as best practices.

To help us understand this interesting intersection and the somewhat complex relationship between structured documents and SOA, I recently interviewed Jake Sorofman, senior vice president of marketing and business development, for JustSystems North America. The sponsored podcast describes the tactical benefits of recognizing the dynamic nature of documents, while identifying the strategic value of exposing documents and making them accessible through applications and composite services via SOA.

Here are some excerpts:
A lot of companies will take on this notion of XML authoring from a tactical perspective. They are looking for new and improved ways to accelerate the creation, maintenance, quality, and consistency of the content that they produce. So they embrace XML authoring tools as the basis for creating valid XML, to manage the lifecycle of those documents and deliverables.

What they realize in the process of doing so is that there is a strategic byproduct to creating XML content. Now, it’s more accessible by various line-of-business applications and composite applications that can consume it much more readily.

If you take the documents that users thrive on and make those available to the SOA, and the composite business processes that that architecture is supporting, then you are able to bridge this gap between the people, the process, and the systems.

We’ve been talking about the notion of unstructured content as a target source to SOA-based applications, but you can also think about this from the perspective of the end application itself -- the document as the endpoint, providing a framework for bringing together structured data, transactional data, relational data, as well as unstructured content, into a single document that comes to life.

We provide the ability to embed this application logic within the document format. The document becomes very attuned to its environment, so it can render information dynamically, based on who you are, what your role is, and where the document is within a process. It can even interact with its environment.

This notion of the dynamic documents ensures that what you’re presenting is always an authoritative reflection of the latest version of the truth within the enterprise. You never run the risk of introducing inaccurate, out of date, or stale information to field base personnel.

You start seeing some blurring some between all these categories of technology around information, search and retrieval, semantics, and document management and data integration. It’s all resulting in a much a richer way of working with and utilizing information.

I don’t think that SOA architects have given a great deal of thought to date to unstructured content and how it plays into SOA architectures. So, there certainly needs to be consideration paid to how you get the information in, in a way that makes it rich to describe, reusable, more akin to relational data than documents themselves.

MokaFive moves desktop virtualization into the cloud

MokaFive, a three-year-old company from Redwood City, Calif., has driven a stake in the ground in the virtualization market with the introduction of its desktop-as-a-service (DaaS) innovation Virtual Desktop Solution.

Combining cloud computing with local execution on a variety of platforms, including a USB flash drive, the solution allows administrators to centrally manage desktops for thousands of employees worldwide.

By creating a "Live PC" desktop, which contains the operating system and application stack, and having it hosted by MokaFive, administrators can distribute, manage, and update the desktop from a single copy on the host computer. Large companies can host the LivePCs on their own servers, if they desire.

Users sync their local desktop with the copy in the cloud, allowing them to always be able to access the latest pristine version. When synced with the Live PC, the desktop is loaded onto the local device, whether a PC or even a flash drive. It then runs as a virtual machine on that device and users can work online or offline. Because execution is local, it reduces the demand on servers and networks.

Changes made by administrators are reflected in the local device whenever users connect to the Live PC. By using a flash drive, users can access their desktop on any x86 -based machine, having all their productivity tools at their fingertips, but leaving no footprint behind once the flash device is unplugged.

While not a household world yet, DaaS isn't brand new. I wrote about it last summer when Desktone announced its virtual desktop platform, with its emphasis on service providers. However, the MokaFive offering focuses on the longstanding problem of managing desktops in mid-sized to large organizations, especially those with remote employees.

The DaaS approach means that companies no longer need to set up their own desktop management infrastructure. MokaFive Virtual Desktop Solution is already in use by customers for disaster recovery, software testing in sandbox environments, secure remote access and lab management. Features of the MokaFive solution include:
  • Faster launches: Predictive Fetch technology makes virtual computers start up faster and update quicker, and users can start using a LivePC before it has finished downloading.

  • Automatic updates: Auto Subscription pushes administrator security updates and application patches to users in a process similar to subscribing to RSS feeds.

  • Self-healing: "Rejuvenation" technology allows users to recover from malware by simply shutting down and restarting a LivePC. On reboot, the operating system and all applications are automatically restored to their original, clean state.

  • Cross-platform and OS flexibility: LivePCs can be installed on a desktop, laptop or any portable storage device like an encrypted flash drive or even an iPod.

  • Enhanced security with BareMetal: This customized Linux distribution runs on bare computer hardware without an underlying operating system, making it optimal for security-critical applications.
Administrators can also send "poison pills" to individual remote devices, allowing them to remove the virtual machine in the case of machines that are lost or stolen, or to remove functionality from contract workers when the contract has finished.

MokaFive offers the product in two flavors: Express Solution is free and gives users an opportunity to create and use public desktops from the MokaFive community lab. The Professional Solution is designed for enterprise use to allow companies to create and distribute private desktops. It also provides technical support.

Pricing, still pending, will be on a per-user basis. A 30-day free trial is available from the MokaFive site.

'Platform as a Service' enables cloud-based software development and deployment lifecycle

Read a full transcript. Listen to the podcast. Sponsor: Bungee Labs.

On demand applications and cloud computing often mean different things to different people. For developers, software as a service (SaaS) is quickly evolving not only as a means to deliver applications -- but as the means to develop them, too.

Taking the notion of "development as a service" to its full potential is the logic behind Platform as a Service (PaaS). To help understand the power of PaaS, we speak in this sponsored podcast to one of the early PaaS pioneers and providers, Bungee Labs.

Learn how software development is entering a new era in this discussion with Phil Wainewright, independent analyst and fellow ZDNet SaaS blogger, as well as with Alex Barnett, the vice president of community and blogger at Bungee Labs. Moderation from yours truly.

Here are some excerpts:
Everything we know is moving to the Web. And what that means in tangible terms is that businesses and service providers and software companies are providing layers of functionality and data that are native to the Web or are Web-oriented.

It’s important when we look at the speed of development to appreciate that three or four folks in a garage in Northern California can come up with a mashed-up service and go out and create a social networking company, for example, quick and easy -- and at low expense. And then, here you are in an enterprise, taking six months to work through a requirements process. It seems as if something has got to change.

IT managers feel the pressure to be able to more rapidly to develop applications and access the data that are based on and being made available through Web APIs. And developers are able to then connect, develop, and build-out new applications based on distributed data, on distributed functionality and react to the business needs.

If you think about customer relationship management (CRM) systems or a certain kind of database -- they are in silos, they are disconnected, or they are very expensive and require lots of proprietary knowledge in order to be able to access the data, and therefore the value. What we are seeing with things like Web oriented architecture (WOA) is a materialization of how we get out of that frustration as an industry -- how we get out of that frustration from business. We want the data and the business intelligence from it, and to be able to get at that from a business perspective.

What we're seeing develop at the moment is kind of a two-tier information technology. On the one hand, you have all of the existing on-premise, legacy applications and all that data that Alex was describing. It's locked away, and IT managers are really puzzling over and grappling with the issue of how to unlock that data. How do they make it more accessible? How do they build more agility into applications infrastructure?

They are looking at things like service-oriented architecture (SOA) and other ways of connecting and integrating the data, while automating business processes within the organization. So that’s one tier.

The other tier that’s developing is this Web-oriented tier, all of these APIs and in-the-cloud resources and applications that are out there on the Web. To take advantage of those connections, you need to build a completely new infrastructure, which is different from the existing infrastructure within the firewall. It has to cope with connecting to external resources, and it has to have different kinds of security, different kinds of identity management.

Building a robust infrastructure to do this is very, very hard. That’s one of the reasons why a lot of enterprises are holding back, and are therefore missing agile opportunities. That’s one of the roles that the PaaS can provide.

[And] that’s what we are trying to define at Bungee Labs. PaaS is one of those terms that we’re going to be hearing more and more. And they are going to be different -- varying levels of definition and interpretation of what that means.

But what we’ve done is put a stake in the ground in this respect, and then saying that in order to really be a PaaS -- and not just any one of those single pieces that you’ve mentioned plus more individual pieces -- that you need to be able to provide the end-to-end services to really call it a "platform."

From the developer’s standpoint, which is the development cycle, this means the tools that they need to develop applications, to be able to then test those applications, to be able to connect to Web services and to combine them, and to have all those kinds of capabilities -- and to then deploy and to make those applications instantly available to the business users. Literally, we mean a URL that is the end-point for the end-user. From that, they can start consuming the application.

The on-demand CRM providers like NetSuite, Salesforce.com, Oracle, and now we’re hearing Microsoft Dynamics, are providing Web services layers over the functionality that they provide to the end users.

We’ve always been able to do a certain level of functional customization around those applications, but when you have the Web services that provide access to the data -- on the programmatic level -- you gain a whole new opportunity to merge, in terms of levels of customization against an existing CRM application, or ERP systems.

This pushes out the expansibility and the increased functionality of the investments that they’re making. It allows for those services to be able to expand that further in a cloud-orientated, Web-orientated way.

You really destroy the misconception that if you go to SaaS you can’t do customization and you can’t do integration. It means that we’re actually doing better customization and better integration than you are capable of doing with many on-premises systems, because it’s actually a more flexible customization. It’s more cost-effective integration because it’s a shared service.

What previously seemed like disadvantages of the SaaS model can be turned on their head and turned into advantages.

IT search and SCM search may together bridge the design time-run time divide

Productivity improvements in software development and deployment strategies will ultimately have to reckon with the lingering lack of feedback between design time and run time.

Software is still a hand-off affair, with developed applications getting tossed into production with little collaboration between the builders and the operators -- before or after the hand-off.

Things could and should be different. Thanks to search-based technologies and services now entering the market, we may be on the verge of a new productivity boomlet that leverages more needles from more haystacks.

With proper access to information about how code actually behaves in real-world use, developers could better produce reliable applications and infrastructure. Architects and systems operators could better anticipate how to meet the demands and service level agreements (SLAs) of quickly provisioned applications if they had greater visibility into the hit on resources -- and potential disruptions -- from newly minted applications and services. Virtualization will only exacerbate the deployment complexities.

Wouldn't it be beneficial then if the information about what goes on "on the other side" were made available proactively to each side of the equation? Search functions applied directly to both sides of the development and deployment fence would allows those open a bright new window into what remains murky and mysterious from the outside.

Developers with proper access to indexes and meta data could use search to quickly find highly specific information about run time environments and stacks as they write and test their code, and as they seek out the best components, objects and methods suitable for specific runtime scenarios.

Conversely, operators faced with slow-running applications -- or worse -- could search into the source code for clues about root causes of glitches, and much easier and faster identify and remediate the problems. They could also clearly point out the impactful issues back to the development and test teams, to prevent the glitch from recurring in the future.

We're already seeing a great deal of value from operations-side search, and the extension of that value due to platform approaches, APIs and open collaboration. Splunk is providing a path on IT search as a platform. [Disclosure: Splunk is a sponsor of BriefingsDirect podcasts, including this one on Splunk Base.]

Other vendors are emerging to fruitfully employee search to the source code management (SCM) space, such as Krugle. Krugle offers a search benefit for open source assets, as well as enterprise development assets.

Now when we can jibe software characteristics and collaborate across the design time-run time divide based on the type of insight that the likes of Splunk and Krugle provide, well then we'll be in a better software age. It may be sooner than we think.

I'm dying to blog on the NYT story, but it's nothing to lose sleep over

The blogosphere is having a field day with The New York Times page one Sunday story on killer blogs. (They came from Africa via South America, and are moving north from Texas right now!)

Funny that the passing of NRA chatterbox Charlton Heston (Let my Ammo Go!) was the NYT story for metro edition, replacing the blogs kill story from the national edition on page one.

So let's honor Charlton by taking a lesson from the NRA: Guns don't kill people, blogs do.

Or perhaps it's, Blogging doesn't kill people, computers do. (I'll give up my laptop when you pry it from my cold, dead hands!)

No, no, wait ... it must be: Heart attacks don't kill people, Mike Arrington does ... or wants to, at least Demo, mainstream media, CNET, and all the other bloggers who take speculative investments and still don't put in the torturous hours he does.

Let's hereby make today, National Tuck a Blogger In For a Nap Day. Sweet dreams, Mike.
