Practical Experiences with SOA

One of the key buzz words this year is SOA. Paul has spent nearly ten years helping customers transform their business and modernize their enterprise. Much of the last five to six years has been spent working on large scale integration projects where SOA is a key methodology. This session will discuss what is SOA, approaches to SOA, and the evolution from Swivel Chair Integration to a full SOA based integrated solution. Since Paul has worked primarily in the public sector in the last four years, he will use real experiences to discuss the problems he has encountered there. These problems range from political (the hardest ones) to technical (the ones we really know how to solve). Finally Paul will spend some time discussing the relevance of technologies such as Enterprise Service Bus, Semantic Web, and Complex Event Processing that are the natural evolution beyond simple Services Oriented Architecture.

Grid Computing, SOA, and Autonomic Computing

This talk will focus on three technologies and how they are utilized to create reliable, globally distributed, virtualized applications. Grid Computing provides an architecture and solution set based on open computing standards that provide for flexible secure coordinated resource sharing among dynamic collections of individuals, institutions & resources (a.k.a. virtual organizations). It provides a secure infrastructure, built on standards like Web Services that provide the core infrastructure needed to provide secure Services Oriented Architecture based applications. Finally, by adding an Autonomic backplane, the marriage of the three technologies provides a solid, secure but flexible infrastructure. This talk will also discuss some of the key issues in creating applications that exploit this infrastructure, and end with a discussion of existing real world applications based on these technologies.

Paul Giangarra is currently an Executive Consultant and e-Government Solutions Architect in the Strategic Technical Relations team, working in the office of the CTO of IBM Software Group Federal. In this role Paul works with all branches of Federal government, such as the Department of Homeland Security, the Department of Defense, and other Agencies such as the State Department and FEMA helping them identify and solve critical and complex IT problems.

Previous to that he was a Senior Consultant and Solution Architect in IBM's e-Business Solutions Services team. In that job, he was responsible for leading large scale Java/Network Computing/e-Business strategy, architecture, and development projects for customers around the world. Since 1996, when he started in this role, Paul has worked with large customers around the world, including Desjardins, Lufthansa, Deutsche Bank, ING, ING Barings, Fireman's Fund Insurance, Banco do Brasil, the U.K. Cabinet Office, the U.K. Department of Social Security, UBS Warburg, and Bank of America. Paul's work included an 18 month secondment to the U.K. Government, where he was the Chief Technology Advisor for the Office of the e-Envoy in the U.K. Cabinet Office. In that position Paul was responsible for the overall technical architecture of the end-to-end e-Government infrastructure for the U.K. government. Following that assignment he developed a detailed e-Government Infrastructure Architecture definition that is being used globally.

In 1988 Paul was appointed the Chief Designer for OS/2. In that position he was responsible for the overall system architecture and design of OS/2, including the first 32-bit version of OS/2. This included the work done in IBM (multiple sites) and Microsoft. Paul holds multiple patents for the parts he helped design. In 1991 Paul was chosen to lead the technical assessment team at Apple that resulted in the formation of Taligent. From 1992-1996 Paul led the architecture of multiple releases of OS/2, including Warp V4. In 1996 Paul helped define PSP's role in IBM's Network Computing future. This work led to Paul's current role.

In 1983 Paul began work on a set of major projects in Europe. These projects kept him Europe for five years (he lived in Germany for three of those years). During most of that period, he was the IBM US Software Architect and specialist for the Bildshirmtext (videotex) system that was developed for the PTTs of both Germany and Sweden. He also helped architect and develop the ISDN access to that system that is now an integral part of Germany's T-Online (the largest ISP in Germany).

Paul started with IBM in 1977 working on Series/1 minicomputer Operating System software development. He was chosen in 1981 to lead the architecture, design, and development effort of a distributed, loosely coupled, fault tolerant, single system image product. That effort completed late in 1982.
