Application modernization Platform as a Service puts focus on business agility

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

Among all the tasks that face the enterprise looking to modernize, improving business agility is first, according to Andy Gordon, Application modernization Platform as a Service (AMPS) director for Unisys. SOA is a part of that effort, he says, because business agility means you are ”developing capabilities that are built to change.”

Today, ”the parts are interoperable,” he said, noting that ”APIs have now become products for a lot of companies and public sector agencies.” These public APIs must be flexible, and be able to support an increasingly broader user base.

”APIs are now recognized as a first-class revenue generator that is solidifying the need to have a service-oriented enterprise – one with the expertise to do services and to be agile,” he said.

Gordon said Unisys is rolling out new services, known as the AMPS Center of Excellence, to help companies improve their application modernization initiatives. The services suite includes an AMPS SOA Governance and an AMPS SOA Operational Software Platform. Some of the new parts are supplied via deals with other software providers such as EMC Documentum, SOA Software and RedHat JBoss – with special Unisys-tailored customizations, based on the company’s extensive work in the field.

SOA infrastructure provides a useful ”backplane,” according to Gordon, to help orchestrate and manage the new style of API. ”A SOA management intermediary is valuable,” he said. ”It brings the management of APIs, security, logging, protocol mediation and a dashboard for watching services activity.”

Still, like others, Gordon emphasizes that ”SOA is something you do, not something you buy.” As a result, SOA Assessment services and SOA Strategy services are part of the AMPS Center of Excellence.

We asked Gordon to share a few useful tips for achieving a successful enterprise SOA. He noted three elements that need to be in place. These follow.

3 Tips for Laying the Strategic Groundwork of a Successful Enterprise-Wide SOA

1. A prioritization process for requirements that emphasizes enterprise priorities in lieu of departmental priorities

2. A highly transparent, participative governance process comprising all stakeholders including a virtual team of service providers led by the SOA Program Director to ensure uninterrupted support for the SOA initiative.

3. An unbounded commitment of an executive sponsor to steadfastly support this organizational transformation.

Setting Priorities
Requirements for services in an enterprise-wide SOA initiative are determined and funded according to the priorities of the enterprise as a whole, rather than those of departments. This forces alignment of business with IT ensuring the goals of SOA are aligned with organizational objectives. That requires participatory governance and communication processes and especially greater interaction with the business lines.

Sound governance begins with a strategic plan that includes the business goals. These goals, in turn, can be transformed into IT requirements with clear line of sight from business goal to IT requirements, followed by high-level design specifications through testing, deployment maintenance, and application end of life.

Executive Commitment
A key responsibility of the executive sponsor (or their delegate) is to be the final decision making authority when the participative governance process reaches a stalemate during a task. The stalemate may occur during requirements prioritization, or there could be a disagreement on the timing for delivering new capability to customers.

The Big Dig and difficult software

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

Software is magic – sometimes it’s magic out of control. Bad software projects, SOA or otherwise, need good analogies. So, we talk about The Long March, The Project from Hell and so on. A recent conversation adds a new analogy to the canon: The Big Dig.

When we spoke with MIT Systems Researcher Jeanne Ross, she pointed to Boston’s Big Dig as an archetypal muffed project. Continued »

When business processes meet software services

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

When driving school instructors go to action films like “Fast and Furious” you can bet their impression differs from that of would-be race drivers in the same audience. “They should fasten their seatbelts,’’ says one. “Vroom-vroom,” says the other. That split often plays out similarly today in business process management.

There, the business side may buy the tools and model the processes, but then leave it to developers in the application integration team to make it all work with enterprise software services.

The business side sees the cool power slides and money in the bank; the development team sees the dangers in impedance mismatch between services and processes. The business side has the vision; the development side cleans up the mess. That is a bridge that must be crossed.

Mobile middleware platform uses open source ESB and BAM

James Denman James Denman Profile: James Denman

Transport for London, the transportation authority for England’s capital city, recently revamped their rider information services with an open source middleware platform. Application development provider Godel Technologies was tasked with upgrading the city’s information services for commuters and tourists. Some of these systems were decades old and in obvious need of new life. Godel Technologies chose a combination of open source ESB and open source BAM to build a middleware platform that supported the reinvigoration of Transport for London’s transportation service applications.

The system supports both one-off inquiries (a user sends a text with their current location and destination and the system replies with the appropriate transit route) and subscriptions to find out about emerging changes in train schedules (for example, a commuter might sign up to find out ASAP when scheduled maintenance effects their route to work).

The backbone of the new system is built on an open source enterprise service bus (ESB) and the associated open source business activity monitoring (BAM) system from WSO2. According to Simon Bidel, head of professional services at Godel Technologies, using a service-oriented architecture with an ESB to separate all the diverse services has made the system easier and less costly to implement.

IBM buys in to mobile middleware, acquires Worklight

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

The drive to ‘develop once and deploy everywhere’ has become more acute as small and big enterprise IT shops have needed to support a wide array of mobile devices. This has led to the appearance of mobile middleware that acts as a moderating stage between the enterprise backend and the mobile frontend.

”One of the challenges for companies is to keep up with the pace of mobility. It is difficult – updating [mobile apps] in some cases on a monthly basis,” said Steve Drake, analyst, IDC. That is where the mobile middleware trend gets impetus.

The trend proved vibrant enough this week for IBM to scoop up Israel-based mobile middleware house Worklight for an undisclosed sum. Continued »

The year of WebOS and open source?

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

HP recently followed up its December plan to release its WebOS mobile platform and development tools with a proposed timeline.  The company also recently released Enyo 2.0, the webOS developer’s tool that enables users to distribute their Enyo-based webOS applications across other platforms. When it’s all said and done, WebOS will be given to the open source community under an Apache license 2.0.

Developers were hoping to have the open source version of WebOS at all at once; however HP announced that the platform and its supporting tools will be released in installments running through September. The first version, Open WebOS 1.0, will be converted to a standard Linux kernel which will make it easier to port to different hardware.

It has been a winding road for WebOS since it was first introduced by Palm in January 2009 as the successor to Palm OS. After Palm was acquired by HP in April 2010, webOS was released to new HP devices. It was practically left for dead, after product line changes and complicated corporate shuffling at the top of HP.

Its troubled path since Palm’s acquisition by HP has caused experts to doubt webOS’s outlook. Al Hilwa, program director for IDC, said it will face an uphill battle.

“The battle for mobile platforms appears to have narrowed considerably,” Hilwa said, “And it is difficult and unrealistic at this point to expect WebOS to see a recovery back into that market.” In a smartphone poll performed by Nielsen in Q2 2011, webOS only had a 2 percent market share in the U.S. compared to 39 percent for Android and 28 percent that for Apple iOS.

However, Hilwa believes that the flexibility of webOS may help the platform become relevant in the future.

“It is quite possible that hardware vendors in the embedded space can take WebOS up for appropriate projects,” Hilwa said, in an email message. “Also, there are parts of WebOS, such as the development framework, that may be used independently.”

This month, HP expects to release and intended project governance model, QT WebKit extensions, JavaScript core, and UI Enyo widgets. In March, HP is set to release graphics extensions, LevelDB, USB extensions. An update for Enyo (2.1), the release of Ares 2.0, and Node services are expected for April. July sets up the ground for September with the release of a system manager dubbed, Luna, a system manager bus, core applications, and another update of Enyo (2.2). The Open webOS beta will be released in August, the company said. – Ryan Punzalan

Security architecture meets enterprise architecture

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

The Open Group got together with the SABSA Institute to give a new security architecture flavor to TOGAF, The Open Group Architecture Framework. It takes the form of some new guidance for working the security angle into enterprise architecture planning. A key to the SABSA approach is willingness to accept some risk while working to ensure security. That’s informed by the notion that security strategies for businesses must admit that a business is here to do business.


“The most secure store never opens,” quips SABSA Academy leader John Sherwood.


The TOGAF-SABSA collection of best practices will find a ready audience as IT moves to endorse more and more Web APIs. And it is not always about security. When Sony’s game playing audience saw their sites down due to security issues they complained – not to get the sites secure, but to get the sites running. Can you say paradigm shift?

Gamesters are different than enterprise apps users. The enterprise app users sue. The balancing act is delicate. Read about the TOGAF/SABSA Guidance.

Why is event processing different?

Jack Vaughan Jack Vaughan Profile: Jack Vaughan

A lot more software architects are working these days to get their arms around the concepts of events and event processing. Many people have reams of transaction data they are beginning to think about correlating and tracking. Sometimes the differences between event processing and other types of processing seem simple – but that simplicity can be deceptive. Continued »

Cloud integrations, the cloud service brokerage, PaaS and more

Brein Matturro Profile: Brein Matturro

By Jack Vaughan


Cloud computing continued to evolve in the past year– and more such evolution is about all we can confidently expect in 2012. As with other, earlier ”game changing” technologies, much of the new frontier is familiar. Cloud momentum is slowing a bit as the real work gets underway – that is, to create useful application integrations on the cloud that are equal or superior to those already available in the data center.


One especial back-to-the future cloud experience comes via the apparent resurgence of Electronic Data Interchange (EDI) or the Value Added Network (VAN), now, in the cloud era, being reconfigured and renamed as the ”cloud service brokerage.” The thinking behind the cloud service brokerage is this: It is all getting kind of complicated – maybe you should consider outsourcing your integration work, especially with the new cloud platforms. Some firms will quickly decide that integration is an expertise they can outsource, others won’t. Read ”Cloud services brokerages can lead way to cloud computing.”


The cloud variety that is known as “Platform as a Service” (PaaS) experienced a shift in emphasis over the course of 2011. The open source developer community has increasingly been turning to Web-based software development tools, and that seemed like a natural fit for cloud computing. So PaaS is starting to mean both a cloud computing runtime and a cloud computing development platform.  RedHat was prominent in 2011 with this type of PaaS, but an assortment of vendors, including some big players, are in the hunt as well, not the least of which is Microsoft.  Planning and strategy for cloud computing is one of the big challenges of 2012 – check out the ”SOA and Cloud Computing Strategy Guide” for more on the topic.


Beyond cloud, a whole host of hot technologies served to enliven 2011. HTML5, TOGAF, EAI, REST and Watson (all considered elsewhere in this year-ending ”This Week” newsletter edition) will flourish or fade in the year ahead. Stay tuned to for more and have a good 2012!
