Software AG has built a global customer base over 35 years by being an early mover in a couple of major technology trends. The company introduced one of the first databases, Adabas, in the 1970s; a platform-independent computer language, Natural, in the 1980s; and an XML server, Tamino, in the 1990s. In an interview with IDG News Service, Peter Kurpick, member of the Software AG executive board responsible for research and development, talked about the company\u2019s evolutionary move from XML servers and integration to new products and services needed to build a service-oriented architecture (SOA) infrastructure.IDG: How did Software AG enter the middleware market?Kurpick: In the early \u201990s, our founder, Peter Schnell, realized a need to connect various systems so that information flows would not be confined to one system. He started a project, the message broker, which is known today as our enterprise service bus. This technology allows you to connect systems of different kinds to exchange information. IDG: And then the Internet came along. What happened then?Kurpick: In the mid-1990s when Internet gained momentum, Software AG detected a need for companies to standardize application tools. The standard was XML and became a core business. We tagged ourselves The XML Company. But that tag is going to disappear soon, as XML is now pretty much a given in the industry; it\u2019s nothing special anymore. IDG: So if you\u2019re not going to be The XML Company any longer, what do you want to be?Kurpick: What we\u2019re doing now with SOA is a natural extension of what we\u2019ve done for the last several years. SOA is a concept of loosely coupling systems and generating new applications based on highly standardized technologies, such as Web services and business process management. We\u2019ve decided to bring a technology stack to the table that covers all the basic components of SOA. This includes opening up and connecting any kind of system. We have a toolset to connect to those systems. And once you\u2019ve connected to three or four systems, you\u2019ll want to orchestrate a new process that takes data from system "A" to system "B" and beyond. This is where our enterprise service bus comes into play.IDG: How does Ajax fit into this?Kurpick: We use this technology to develop enterprise screens, or "mash-ups," that companies can deploy on top of their systems to have an integrated view of data being generated by a variety of applications. This is what our crossvision suite is all about.IDG: How do you make customers understand what SOA is all about? Kurpick: We tell customers they need one central place, an SOA registry\/repository. Here they register all their metadata, or SOA "artifacts," which describe interfaces, business processes, Web services and more. The repository is a library of sorts where users store all the ways they connect systems, providing a map of their IT landscape. It allows them to govern and manage their SOA infrastructure. IDG: So this is your interpretation of SOA\u2014to work through this repository? Kurpick: We say that an SOA registry\/repository is a must. It allows businesses to govern the lifecycle of SOA components, such as services, processes and policies.IDG: Is this repository approach unique to you?Kurpick: There are only two companies in world doing this right now: Software AG and Hewlett-Packard, via an acquisition. HP acquired Mercury Interactive, which owned Systinet\u2014the only competitor with a similar approach.IDG: Are there other interpretations of SOA with the library?Kurpick: You really can\u2019t run a large-scale SOA landscape without a central library. As with any library, you need to know where the books are. With SOA, you need to know where all the services are you want to link and how to link them.IDG: And you help with your own proprietary technology?Kurpick: Our technology is entirely based on open standards. We see ourselves as a neutral player in the integration space. We\u2019re not biased toward SAP AG or Oracle or any other vendor of business applications, for that matter. Our mission is to integrate heterogeneous IT landscapes. Businesses prefer to enable new processes on what they already have. They don\u2019t want to embark on huge conversion programs.IDG: When companies follow an SOA path, do they need to invest heavily in consultants?Kurpick: They need some level of consultancy. SOA is a learning process. We can guide businesses and help them avoid interruptions. Our technology is based on standard ways of doing things\u2014for instance, Eclipse as a development environment or Java as a standard way of developing code. Large companies can do much in-house. So it\u2019s really a question of how large you are and how much you want to do in-house. IDG: So no more XLM\u2014SOA is the future. But SOA can go away too, right?Kurpick: SOA is an architectural concept, and I expect it will be around for at least the next 10 years or longer. The concept is really only at the beginning.-John Blau, IDG News Service (Dusseldorf Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
