By some measures, General Motor’s Volt hybrid electric car is moving to market very quickly. At IBM’s Rational Innovate 2011, Bill Bolander, technical fellow, General Motors, featured the Volt as an example of successful software reuse.
He cited some examples of reuse related savings for the Volt, estimating that 90% of the software developed for GM’s conventional engines was reused on the Volt. Moreover, 60% of the HVAC software was reused. Furthermore, Volt has a reconfigurable LCD display for its instrument cluster, he said, adding that it benefits from 90% reuse of software components from a conventional cluster.
Reused components have well understood metrics that allow for “more predictable processes and planning,” according to Bolander. It is ironic, he noted, that rote reuse can serve to free-up developer time that can then be concentrated on innovation.
“Our vehicles are differentiated more and more by software capabilities,” said Bolander. Interaction between software engineers and automobile systems engineers is now a daily fact of life, he said.

When cloud computing first appeared it looked something like grid computing – albeit with a goodly dose of new age virtualization. The fact was that cloud carried with it the seeds of a revolutionary data architecture that greatly reduced reliance on the relational data base. Relatively new companies such as Google and Amazon built large-scale Web applications – ones that diminished the RDB’s role – and they became the poster children for the cloud … Continued »
We wanted to update you on our June 2, 2011 ”SOA in Action: Navigating SOA, Integration and the Cloud” Virtual Trade Show. We have just added noted SOA practitioner Melvin Greer to the event’s panel. We are sure that you will benefit from Greer’s and other participants’ take on SOA and cloud computing — two key and somewhat intertwined architectures of the day.
Melvin Greer is senior fellow and SOA chief architect at Lockheed Martin. Importantly, he is a member of the Government Cloud Computing Community of Interest and the OMG’s recently formed working group on cloud computing standards. Through his practice, and as one of a very few in the forefront of cloud standards work to date, Greer has gained unique experience in actual cloud use cases.
Greer joins SearchSOA.com expert and Bick Group CTO and Founder David Linthicum on our end-of-the-day panel entitled, ”What can go wrong with data in the cloud.” No, we won’t just look at failures; in fact, there are aspects of merit in cloud computing. But, we will follow the story where it takes us. Have your questions ready, please!
There is much more to the event, of course. Forrester’s Randy Hefner will consider how to combine cloud computing and SOA for economic advantage. Gartner’s Daryl Plummer will look at the new forms that integration takes as you move from SOA to the cloud and beyond. Lustratus Group’s Steve Craggs will discuss SOA-based cloud security, governance and performance. And the aforementioned David Linthicum will dissect the data integration challenges that come with the cloud.
Surging interest in cloud computing has swept up many a CEO. Architects, CTOs and development managers must be ready to create a cloud and SOA playbook. Our event is designed to help you in that pursuit. The Virtual Trade Show can be viewed from just about any place with Internet access. For more information, follow this link: ”SOA in Action: Navigating SOA, Integration and the Cloud.” Remember, it is set for June 2, 2011. Sign up now. We hope you can be there.

The role of development in cloud computing has been bumpy through the few years that cloud architecture has been discussed. Most attention has been on the runtime and the data center, rather than the development side of the equation. That may be changing as some new Platform as a Service (PaaS) offerings come online.
By some estimates, continuous integration may be the fulcrum for PaaS. If development teams are going to work on the cloud and ultimately develop for the cloud, they are likely to do their work based around an open source continuous integration engine residing on the cloud, or so the thinking goes. Take as an example CloudBees.
CloudBees offers the Jenkins open source continuous integration server as a cloud service. The company claims exceptional continuous integration expertise, based particularly on the reputation of Elite Developer and Architect Kohsuke Kawaguchi, its ”Elite Developer and Architect.” Kawaguchi was primer driver behind Hudson. His firm, InfraDNA, formed after the somewhat acrimonious fork of Hudson and Jenkins in the wake of Oracle’s purchase of Sun Microsystems, was acquired by CloudBees in November of 2010.
CloudBees founder and CTO Sacha Labourey says CloudBees goal is to handle the operations tasks needed to get an application from development to deployment, noting how many of those non-development tasks are arduous for developers.
“Today, developers end up maintaining Jenkins, and maintaining the machines it runs on,” said Labourey. ”It can get cumbersome.”
”For PaaS to take off, it has to be more than a runtime, it has to be a development stage too. It needs to cover the entire application lifecycle,” he said.
The open source continuous integration engine as core to a cloud platform service bears watching. As CloudBees’ s Labourey says, a certain class of cloud may come from the bottom up to the top on the back of open source software.
[Postscript: In early 2011, with Oracle’s possible trademark control of “Hudson” among the issues of contention, the formal open source Jenkins project was created. The fractious split between the Hudson and Jenkins software camps reached a new stage earlier this month when Oracle proposed that the Eclipse Foundation create a Hudson project in Eclipse that included Hudson core code contributed by Oracle.]
Do you trust outside software developers more than in-house software developers? Such may often be the case according to a recent survey conducted by Forrester Consulting on behalf of software tester Coverity. The news is a bit unsettling. Continued »
On SearchSOA.com, recent topics ranged from the venerable mainframe to the upstart cloud architecture. Experts in the field shared their views. Let’s take a quick look at some of those opinions.
Forrester analyst Phil Murphy pointed out that one size does not fit all when it comes to mainframe legacy modernization. Some mainframe code is not so old that it does not have some flavor of object-oriented software. Some code is in good shape, and thus, given your overall strategy and compute horse power, it may be an economical candidate for re-hosting. The question to consider is whether you have a well-structured application, noted Murphy. Read ”Modernize? Consider the MIPS” on our site.
Why does the corporation look so favorably on cloud computing? It seems to smell like cost reduction. But ROI studies do not always confirm the cloud savings. Are IT departments doing thorough ROI studies on cloud? Fewer than you might expect, according to Chris Harding of The Open Group. ROI should be measured, and the variability of your processing load is a matter to consider as you do those measurements, said Harding. Read about ”Cloud computing myths and the developer’s role” on SearchSOA.com.
“If you have a fairly steady processing load, cloud doesn’t make much sense, but if you have a variable load it can be appealing,” he says. However, Harding theorizes that respondents from larger organizations may see enough variability within business units and departments, for example, that the overall load balances out – making an ideal environment for private cloud. “That will probably be cheaper than going to an external cloud supplier,” he adds.
We spoke as well with analyst Judith Hurwitz. The topic again was cloud computing. She urged users to consider that some of this is new, and some is not. As teams move their middleware work to the cloud, they find the fundamental rules apply – that building out application servers remains part of the job. It is, in fact, sometimes a most tedious part. “Even though it is on a cloud, the issues of enterprise development are still there,” said Hurwitz, pointing to configuration and metadata handling as examples of such issues.

Traditionally, enterprise system bus (ESB) developers could laboriously hand code or they could adopt tools from vendors that could speed up the process but at a cost – the tools could themselves be complicated and they tended to obscure access to underlying code, limiting the nuances a developer could apply.
MuleSoft, a Bay Area software company has announced a new design product called Mule Studio, an Eclipse-based graphical design tool, which is said to support ESB design ”round-trip editing.” That means developers can design and edit the ESB application interchangeably in either the graphical tool or in XML.
Mateo Almenta-Reca, Director of Product Management at MuleSoft claims vendors such as TIBCO and IBM have provided tools that made it easier to get started but made long-term maintenance more difficult. He suggests the MuleSoft tools allow developers to do a deep dive if they want, and make changes in the code.
Red Hat’s JBoss World 2011 in Boston last week presented a unique view on some of the issues that press upon CTOs, software architects and development managers today. Of course, you would expect a unique view, given the company’s distinctive open source software lineage. Continued »
Video: When Site Editor Jack Vaughan got back from Red Hat’s JBoss World, he filed a brief on a caching grid, something Red Hat looks to bring to the fore. In fact, the company is chasing others – big and small – in the data cache quest. Will JBoss succeed in positioning this technology as a standard?
