Talk 1: Enterprise 2.0: SOA, SaaS & Web 2.0

Enterprise IT departments are making or considering major investments in ‘service oriented architectures’ driven by increasing standardization in web-services technology. At the same time, ‘software as a service’ solutions are being explored by enterprise business units as providing an alternative to the traditional enterprise software model. Meanwhile, web 2.0 ‘mash-ups’, ‘rich browser interface’ technologies, and ‘wiki’-based collaboration tools are becoming widely used in the consumer space. We discuss the potential business impact of these global trends, as well as their relationship with global development models and open source software.

Speaker: Dr. Gautam Shroff

As Vice President, Technology Programs, Tata Consultancy Services, Dr. Shroff is responsible for defining technology joint business-R&D programs across TCS, recommending directions to existing R&D efforts, spawning new R&D efforts (internal or external) and proliferating the resulting technology and intellectual property across TCS’ core businesses. Additionally he also heads TCS’ Technology Innovation Lab (www.ilab-tcs.com), which focuses on applied research in open architectures, grid computing, service oriented computing, semantic computing and human computer interfaces.
Dr. Shroff has in the past been directly responsible for TCS business in enterprise technical consulting in the areas of enterprise architecture, IT strategy, application integration, platform selection and data modelling. He has worked on applied research in the areas of software architecture and distributed objects, and has published several papers on the subject.
Dr. Shroff joined TCS in 1998 and managed the design and development of the technical architecture for Quartz, TCS’ software product for international investment banking. In this role he also productized and deployed TCS’ model driven architecture (MDA) tools to enable component based development using large scale code-generation.
Prior to joining TCS, Dr. Shroff was a faculty member at the California Institute of Technology, USA, and thereafter an Assistant Professor at the Department of Computer Science and Engineering at the Indian Institute of Technology, Delhi. At IIT, he worked in the areas of computational mathematics, parallel computations and distributed systems. He has also held visiting positions at NASA Ames and Argonne National Labs, where he has worked on parallel scientific computing. In 1994 he was conferred the ‘Young Scientist Award’ from the Department of Atomic Energy. During this time, he was also a consultant to TCS, Indian Railways and other organizations.
Dr. Shroff graduated from the Indian Institute of Technology, Kanpur, India, in 1985 and received his Ph.D. in Computer Science from Rensselaer Polytechnic Institute, NY, USA, in 1990.

Talk 2: Next generation Web Services technologies: Windows Communication Foundation

Abstract

Windows Communication Foundation is Microsoft's unified programming model for building Web service. It extends the .NET Framework to enable developers to build secure, reliable, and transacted Web services that interoperate across platforms.
WCF takes Web services to the next level. Support for the WS-* protocols means that Web services can easily take advantage of interoperable security, reliability, and transaction support required by businesses today.
In this session we will demonstrate how WCF works. We will also provide some best practice regarding security, performance and interoperability learned in early adopter projects.

Talk 1: Do Web Services make our life really simpler?

With "Saferpay" Telekurs Card Solutions provides a payment solution for E-Commerce shops to accept credit card based payments on-line. As over 5'000 merchants use this service and more than 10 millions of transactions a year are being processed, the simplicity of integration for Saferpay becomes an important strategic aspect to Telekurs Card Solutions. In the middle of 2005, Saferpay went life with Web Service technology as its core service.
In the form of a field report this presentation will highlight the motivation that lead to the development of the Web Service. It will also share first hand experiences with regard to implementation- and life cycle management issues. The aim of the presentation is to share experience and to help the audience to assess common difficulties that can occur with the implementation of Web Serivces.

Speaker: Giorgio Scherl, Telekurs Card Solutions

As "Head of Product Management POS & E-Commerce" at Telekurs Card Solutions Giorgio Scherl is  responsible for the product development of credit card based payment products targeted at point of sales (POS) and E-Commerce merchants. From 1997 until 2002  Giorgio Scherl ran multiple entrepreneurial startup companies in New York. During this time he designed and helped to develop various  web based business solutions. Before his time in New York, he helped to establish Union Bank of Switzerland's (UBS) first Internet presence and security architecture.

Talk 2: Architectural Decisions as Service Realization Methodology in Model-Driven SOA Construction - From Analysis-Level Process Models to Service Abstractions of Quality and Style

On Service-Oriented Architecture (SOA) delivery projects, practitioners concern themselves with the characteristics of good services and how such services can be designed. For instance, they look for advice regarding interface granularity and criteria to assess whether existing software assets are fit for reuse in SOA environments. As for all nontrivial modeling problems, there are no straightforward answers to these questions; a full-fledged service modeling methodology is required, consisting of service identification, specification and realization techniques. Service identification and specification are well covered by methodologies such as Service-Oriented Modeling and Architecture (SOMA); for service realization, architectural decision models can be leveraged. Unlike other approaches to documenting software architectures, architectural decision models capture the expert knowledge leading to certain designs rather than actual designs. At present, the construction of architectural decision models is an education- and labor-intensive undertaking. Architectural decisions are therefore often taken without model support; the rationale behind the decision making is not captured.

In this talk, we position SOA-specific architectural decision models as a prescriptive service realization technique and present an SOA decision catalog harvested from a number of full-scope SOA delivery projects. For illustration purposes, we will use two large-scale SOA and Web services deployments, the BPEL enablement of the order management application of a telecommunications wholesaler, and the Web services externalization approach followed by a shared service provider in the finance industry. We will look at drivers for the projects as well as the solution architectures, and share some of the lessons learned.
