Web Services Edge 2002 East Keynote

Eric Newcomer, CTO, IONA, Cites Data Independence as Prime Benefit of Web Services

WSJ recently caught up with Eric Newcomer, chief technology officer of IONA, and spent a few moments discussing trends in the industry. A member of the XML Protocols and Web Services Architecture working groups at the W3C, Eric is a respected industry expert, and will be one of the featured Keynote speakers at the Web Services Edge 2002 East conference, June 24-27, at the Jacob K. Javits Convention Center in NYC.

WSJ: Are Web services a reality in terms of delivering the ROI that technology investments have promised?

Newcomer: Web services represent a broad range of technologies and capabilities, some of which are already available and some of which are just starting to emerge. Therefore some of the ROI benefits are already available, while others will be delivered over time.

The investment in a basic Web services creation product such as IONA's XMLBus is very small - it's available for free evaluation, as are comparable toolkits from other vendors. But the return on XMLBus is very high, since it can successfully and easily bridge .NET, J2EE, and CORBA; interoperate with many other Web services products; import WSDL from other sources; generate WSDL from existing objects and classes; generate clients; and so forth.

Other products, such as application servers, integration brokers, and database management systems are becoming "Web service-enabled," which presents a more complicated ROI picture, since the value of the investment in these cases is more inherent in the existing product than in the Web services layer.

Web services products are delivering ROI today, but in as soon as two to three years, Web services will commoditize costly software products, and commoditize the skills of developers needed for enterprise integration projects.

WSJ: When do you think we will see serious Web services in place? In other words, will they be mainstream in a year, two, ten, etc.?

Newcomer: Web services are already serious technology for some applications, such as transmitting large amounts of data across the Internet, and are becoming mainstream very quickly for program-program interactions over HTTP. However, it will take two to three years, possibly even five years, before the technology matures to the extent that it can be considered a replacement for existing mission-critical technologies. It's a bit like the adoption curve of CORBA, which is now reaching mainstream after about a decade.

WSJ: Are there particular industries that are taking to Web services faster than others are?

Newcomer: The retail, telecommunications, and financial industries are taking to Web services quickly, specifically around the implementation of vertical standards for XML protocols and documents such as ebXML, RosettaNet, and UCCnet, which are supported in our Orbix E2A Collaborate. Orbix E2A Collaborate is a document-oriented integration broker that supports these vertical industry standards and features a business protocol framework that's easily extensible. Orbix E2A Collaborate also includes a suite of ERP, CRM, and technology adapters and a graphical business process engine for defining business collaboration flows. These flows can also be exposed using WSDL, so that Orbix E2A Collaborate can receive documents sent using Web services messaging. Orbix E2A Collaborate provides the enterprise quality of services toward which Web services are evolving.

WSJ: What is the single largest impediment to Web services besides lack of standardization?

Newcomer: Security. Whenever you open up access to programs over the Web, you open up the possibility of being exposed to malicious interactions, either from someone pretending to be a trusted source of information or from someone pretending to be authorized to access private data. IONA's Orbix E2A XMLBus and Collaborate offerings have a strong focus on industrial-strength security solutions for encryption and authentication for this reason.

WSJ: What do you see as the single largest benefit of Web services?

Newcomer: Web services provide data independence, and the capability to bridge disparate technologies. They have the potential to finally solve the enterprise integration problem using commodity software. Data from any source can be converted into XML; once in XML it can be transformed into multiple other XML forms, and converted from XML into any destination. Web services represent a set of conventions and standard mechanisms for achieving this.

See Eric Newcomer in person at Web Services Edge 2002 East, Jacob K. Javits Convention Center, NYC, NY, on Wednesday, June 26. He'll give a keynote speech on Web Services: Integration Technology for the 21st Century, and will participate in the keynote panel " Immediate ROI with Web Services."

Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
"NetApp's vision is how we help organizations manage data - delivering the right data in the right place, in the right time, to the people who need it, and doing it agnostic to what the platform is," explained Josh Atwell, Developer Advocate for NetApp, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, compared the Jevons Paradox to modern-day enterprise IT, examin...

Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches. In his session at DevOps Summit, Gordon Haff, Senior Cloud Strategy Marketing and Evangelism Manager at Red Hat, will discuss why containers should be paired with new architectural practices such as microservices ra...
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016.

In his session at 16th Cloud Expo, Reuven Harrison, CTO and Co-Founder of Tufin, ...
DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav...
Many organizations are now looking to DevOps maturity models to gauge their DevOps adoption and compare their maturity to their peers. However, as enterprise organizations rush to adopt DevOps, moving past experimentation to embrace it at scale, they are in danger of falling into the trap that they have fallen into time and time again. Unfortunately, we've seen this movie before, and we know how it ends: badly.
TCP (Transmission Control Protocol) is a common and reliable transmission protocol on the Internet. TCP was introduced in the 70s by Stanford University for US Defense to establish connectivity between distributed systems to maintain a backup of defense information. At the time, TCP was introduced to communicate amongst a selected set of devices for a smaller dataset over shorter distances. As the Internet evolved, however, the number of applications and users, and the types of data accessed and...
