Toufic Boubez Dr. Toufic Boubez is a well-respected SOA and Web services pioneer. He is a Certified SOA Trainer for SOA Systems Inc., the founder of SOA Craftworks, and was the founder and CTO of Layer 7 Technologies, one of the most successful vendors in SOA Governance and Security. Prior to Layer 7, he was the Chief Architect for Web Services at IBM's Software Group, and the Chief Architect for the IBM Web Services tools. At IBM, he founded the first SOA team and drove IBM's early XML and Web Services strategies. As part of his early SOA activities, he co-authored the original UDDI specification, and co-authored a service description language that was a precursor to WSDL. His current activities span SOA Security, SOA Governance and the impact of Cloud Computing.
Toufic is a sought-after presenter and has chaired many XML and Web services conferences, including XML-One and WebServices-One. He has also been actively involved with various standards organizations such as OASIS, W3C and WS-I. He was the co-editor of the W3C WS-Policy specification, and the co-author of the OASIS WS-Trust, WS-SecureConversation, and WS-Federation specifications. He has also participated on the OASIS WS-Security, SAML and UDDI Technical Committees.

Dr. Boubez holds a Master of Electrical Engineering degree from McGill University and a Ph.D. in Biomedical Engineering from Rutgers University.


Paul C. Brown Dr. Paul C. Brown is a software and systems architect with a deep background in the design of distributed information systems. His early work focused on fault-tolerant real-time monitoring and safety systems. Subsequent work on distributed decision support systems evolved into a more general interest in the design of event-driven distributed systems using model-based design methodologies. His model-based tool architectures are the foundation of a diverse family of applications that design distributed control systems, process control interfaces, internal combustion engines, and NASA satellite missions. Extensive design work on enterprise-scale information systems led Dr. Brown to recognize that service-oriented architectures inherently structure both business processes and information systems. This led to the concept of Total Architecture: that business processes and information systems must be architected together. The Total Architecture approach has proved itself building numerous information systems for global enterprises and the Fortune-500.
Dr. Brown has authored a pair of books on Total Architecture from Addison Wesley: 'Succeeding with SOA: Realizing Business Value through Total Architecture'; and 'Implementing SOA: Total Architecture in Practice'. Dr. Brown received his BS in Electrical Engineering from Union College, and his MS and Ph.D. in Computer Science from Rensselaer Polytechnic Institute. He is presently a Principal Software Architect at TIBCO Software Inc.
