Discussion features insights into using RESTful services plus a cool iPhone app

For a quick update on creating RESTful services, check out IONA Technologies' webinar moderated by yours truly. The recent webinar was part of IONA's "Open Source in the Enterprise" series, and is archived on their Website. (Note: free registration required.)

Included in the discussion is my introduction on how to increase value payback, followed by a presentation from Adrian Trenaman, distinguished IONA consultant, on creating RESTful services using FUSE.

Finally, Roland Tritsch, IONA director of services in EMEA, demos a really cool method for accessing RESTful FUSE services from the iPhone. [Disclosure: IONA is a sponsor of BriefingsDirect podcasts.]

IONA has been making the news recently, especially the announcement just a few weeks ago that it was being acquired by Progress Software. A few weeks earlier, IONA released a set of enhancements to Artix Data Services designed to reduce risk exposure and operational costs.

Just over a year ago, I produced a podcast with Dan Kulp, principal engineer at IONA, and Debbie Moynihan, director of open source programs at IONA, in which we discussed the incubation Apache CXF project.

In the past, data was structured, secure and tightly controlled. The bad news is that the data was limited by the firewall of personnel, technologies, and process rigidity. Today, however, the demand is for just-in-time and inclusive data, moving away from a monolithic data system mentality to multiple sources of data that provide real-time inferences on consumers, activities, events, and transactions.

The move is in the ownership of data value to the very people who really need it, who help define its analysis, and who can best use it for business and consumption advantage. Analysis and productivity values rule the future of data as services.

But how to jibe the best of the old with the needs of the new? How to use data services as onramps to SOA? How to bring data together for federated analysis? And how to use the power of open source licenses and community to encourage the further federation of data as standardized consumable services?

To answer these questions and to learn more about the quickly evolving data services landscape, I recently spoke with Paul Fremantle, the chief technology officer at WSO2; Brad Svee, the IT manager of development at travel management leader Concur Technologies; and James Governor, a principal analyst and founder at RedMonk.

Here are some excerpts from the resulting podcast:

The live, connected world needs to be managed properly and it's very, very difficult to build that as a single monolithic system. ... The [new] model is of keeping the data where it belongs and yet making it available to the rest of the world.

Our data is trapped in these silos, where each department owns the data and there is a manual paper process to request a report. Requesting a customer report takes a long time, and what we have been able to do is try to expose that data through Web services using mashup type UI technology and data services to keep the data in the place that it belongs, without having a flat file flying between FTP servers, as you talked about, and start to show people data that they haven't seen before in an instant, consumable way.

It seems clear that the status quo is not sustainable. There is inherent risk in the current system, and simply retrofitting existing data and turning it on as a service is not sufficient.

We have been trying to free up our data, as well as rethink the way all our current systems are integrated. We are growing fairly rapidly and as we expand globally it is becoming more and more difficult to expose that data to the teams across the globe. So we have to jump in and rethink the complete architecture of our internal systems.

The browser becomes the ubiquitous consumption point for this data, and we are able to mash up the data, providing a view into several different systems. Before, that was not possible, and the additional piece of moving the file between financial system, for example, we are able to not have to pull files, but actually use Web services to send only the data that has changed, as opposed to a complete dump of the data, which really decreases our network bandwidth usage.

[Yet] most of the data that we are dealing with is fairly sensitive, and therefore almost all of it has a need for at least per-user access basis, as well as, when we are transporting data, we will have to make sure that it's encrypted or at least digitally signed.

What we have built is what we call WSO2 Data Services, which is a component of our application server. The WSO2 Data Services component allows you to take any data source that is accessible through JDBC, MySQL databases, Oracle databases, or DB2, but, in addition, we also have support for Excel, CSV files, and various other formats and very simply expose it as XML.

Now this isn't just exposed to, for example, Web Services. In fact, it can also be exposed by REST interfaces. It can be exposed through XML over HTTP, can even be exposed as JSON. JavaScript Object Notation (JSON) makes it very easy to build Ajax interfaces. It can also support it over JMS, and messaging system.

So the fundamental idea here is that the database can be exposed through a simple mapping file into multiple formats and multiple different protocols, without having to write new code or without having to build new systems to do that.

What we're really replacing is ... where you might take your database and build an object relational map and then you use multiple different programming toolkits -- one Web services toolkit, one REST toolkit, one JMS toolkit -- to then expose those objects. We take all that pain away, and say, "All you have to do is a single definition of what your data looks like in a very simple way, and then we can expose that to the rest of the world through multiple formats."

I think that open source is absolutely vital to making this work, because fundamentally what we're talking about is breaking down the barriers between different systems. As you say, every time you're pushing the proprietary software solution that isn't based on open standards, doesn't have open APIs, and doesn't have the ability to improve it and contribute back, you're putting in another barrier.

Everyone has woken up to this idea of collaboration through Web 2.0 websites, whether through Flickr or FaceParty or whatever. What the rest of the world is waking up to is what open-source developers have been discovering over the last five to 10 years. Open source is Web 2.0 for developers.

Open source drives this market of components, and it's exactly the same thing that happened in the PC market. As soon as there was an open buy off that wasn't owned by a single company, the world opened up to people being able to make those components, work in peace and harmony, and compete on a level playing field. That's exactly where the open-source market is today.

That's exactly the sweet part in my opinion. I can shake and bake, I can code up a bunch of stuff, I can prototype stuff rapidly, and then my boss can sleep well at night, when he knows that he can also buy some support, in case whatever I cook up doesn't quite come out of the oven. I see there's a kind of new model in open source that I think is going to be successful because of that.

Sybase rides growing database business into mobility innovation, says Chen at user conference

Sybase Chairman, CEO and President John Chen opened the TechWave Sybase user conference today with a slew of product announcements and a proud pointer to a growing database market -- growing at double-digit revenue growth (even if you're not IBM, Microsoft and Oracle).

Chen boasted 38 percent database revenue growth in Sybase's latest quarter, outstripping his formidable competitors. He told the crowd of IT users gathered in Las Vegas that the underlying database business is strong.

Sybase at the 10th annual event has announced tools, analytics and mobile products that target Sybase's global customer base of developers, database administrators, operators as well as its burgeoning enterprise mobility infrastructure solutions providers.

"We're making a run at the major data warehouse providers ... and we think we can compete very well," said Chen. "Things are working very well for the company."

For mobility, in a year where the Apple iPhone gained the lion's share of attention (despite Symbian's dominance), Sybase is driving toward the "unwired enterprise" to bring the analytics world together with the mobile tier and handheld delivery world. "The more devices and the more operating systems ... the better Sybase will be," said Chen.

Based on any metric data continues to explode across the IT landscape, said Chen. And the emphasis on real time and deep and wide analytics is only accelerating. Chen calls it "decision ready information."

Chen asked -- practically implored -- the users to get more into their mobility strategy, to unwire their enterprises.

Sybase Senior Vice President Raj Nathan said that mobile computing is overtaking older forms of communications and computing, as a theme for his portion of today's keynote presentation. But the current IT infrastructure can not well support this trend to mobility and information delivery out to the mobile edge.

"If you look at who is accessing the data, it's no longer just the employees ... and the demands of the non-employee for accessing from outside the firewall ... is much different. Today's architectures will not meet this demand," said Nathan.

Applications also need to be designed to be transaction-centric, said Nathan. What developers have to deal with has changed. "It's not just transactional applications, it's analytics, mobile, and messaging applications," he said. "These applications come from outside the firewall and through a mobile device in a unstructured, ad hoc form."

This all requires a shift in IT architectures, said Nathan. We need message-oriented interfaces. Data, applications, and tools -- all need to adjust. You need to handle complex analytics as a part of the process, not an after-thought, he said.

"The demands of information are changing, and you need a different set of architecture paradigms to make this happen," said Nathan. "Information delivery is even more important. It's time to evolve this and not go through a full set of replacements."

Amazon invests in cloud deployment venture as Elastra raises another $12 million

Elastra Corp., a cloud computing startup with a focus on ease of deployment, today announced a second round of funding, including participation from Amazon, which continues its investment ramp-up in cloud-based ventures.

The Series B funding for the San Francisco, Calif.-based Elastra, totals $12 million. Other participants were Bay Partners and Hummer Winblad Venture Partners, which took part in the first round of funding last year.

The cloud topic continues to heat up, with today's announcement that AT&T is jumping in. More from ZDNet's Larry Dignan. It's a no-brainer for telecos to be in on this, and it sets the stage for more tension between software vendors and service providers.

As for Elastra's Cloud Server, it provides point-and-click configuration, push-button deployment and automated management and dynamic monitoring of application infrastructure software and systems. The company's elastic computing markup language (ECML) and elastic deployment markup language (EDML) allow for extensibility and portability of applications across public and private clouds.

With this approach businesses and IT organizations don't have to script, monitor and scale their application infrastructure by hand, nor are they locked into “cloud silos” from a single provider.

For Amazon, which has been providing cloud infrastructure services for the over two years, this is the second foray into funding cloud ventures in the last three weeks. In July, Amazon chipped when Engine Yard raised $15 million.

I saw the potential for Elastra's approach, when the company arrived on the scene last March.

As virtualized software has become the primary layer over now-buried hardware that architects and engineers must deal with, we should expect more tools and “bridging” technologies like Elastra to emerge to help grease the skids for what can (and should?) be deployed in clouds. The software then becomes agile services that can be provisioned and consumed via innovative and highly efficient business models and use-based metering schemes.

. . . the database-driven product can help bring applications rapidly to a pay-as-you-use model. Enterprises may be able to provide more applications as services, charging internal consumers as a managed service provider.

I said at the time that the segue to the cloud could come sooner than many people might think. It looks like that prediction was on the mark.

SOA places broad demands on IT leadership beyond traditional enterprise architect role, says Open Group panel

Read a full transcript of the discussion.

Defining the emerging new role of enterprise architects (EAs) in the context of services-oriented architecture (SOA) is more than an esoteric exercise. It also helps define the major shifts now under way from SOA activities in enterprises and large organizations. These murky shifts come down to defining how IT is to be managed anew in the modern organization.

To help better understand the shifting requirements for personnel and leadership due to SOA, The Open Group presented a panel on July 22 at the 19th Annual Open Group Enterprise Architect's Practitioners Conference in Chicago. I had the pleasure to moderate the discussion, on the role and impact of skills and experience for EAs in both the public sector and the private sector.

Our panel of experts and guests included Tony Baer, senior analyst at Ovum; Eric Knorr, editor-in-chief of InfoWorld; Joe McKendrick, SOA blogger and IT industry analyst; Andras Szakal, the chief architect at IBM's Federal Software Group, and David Cotterill, head of innovation at the U.K. Government Department for Work and Pensions.

Here are some excerpts:

Within the government [sector], enterprise architecture is, I would say, trending more toward the political aspect, to the executive-level practitioner, than it is, say, an integrator who has hired a set of well-trained SOA practitioners.

The enterprise architect is really more focused on trying to bring the organization together around a business strategy or mission. And, certainly, they understand the tooling and how to translate the mission, vision, and strategy into an SOA architecture -- at least in the government.

I think the technical background can be taken as a given for an enterprise architect. We expect that they have a certain level of depth and breadth about them, in terms of the broadest kind of technology platforms. But what we are really looking for are people who can then move into the business space, who have a lot more of the softer skills, things like influencing … How do you build and maintain a relationship with a senior business executive?

Those are kind of the skills sets that we're looking for, and they are hard to find. Typically, you find them in consultants who charge you a lot of money. But they're also skills that can be learned -- provided you have a certain level of experience.

We try to find people who have a good solid technical background and who show the aptitude for being able to develop those softer skills. Then, we place them in an environment and give them the challenge to actually develop those skills and maintain those relationships with the business. When it works, it's a really great thing, because they can become the trusted partner of our business people and unmask all the difficulties of the IT that lies behind.

We are software architects, but we are really trying to solve the business problem. ... I would look for people [to hire] who have deep technical skills, and have had experience in implementing systems successfully. I have seen plenty of database administrators come to me and try to call themselves an architect, and you can't be one-dimensional on the information side, although I am an information bigot too.

So you're looking for a broad experience and somebody who has methodology background in design, but also in enterprise architecture. In that way, they can go from understanding the role of the enterprise architect, and how you take the business problem and slice that out into business processes, and then map the technology layer on to it.
