    Presentation Overview

    Building Reliability and Performance into Web Services

    Enterprises are building complex interoperable information systems using Web Service technology today. By choosing the right system architecture, tools and techniques these systems scale and perform well as system usage increases. Frank Cohen, CEO, of PushToTest will show how leading companies such as Elsevier Science and 2Wire used advanced testing techniques, tools and methodologies to deliver high reliability and good performance in their Web Service-based systems.

    Frank’s presentation will answer questions such as:

    • How will the system perform in production?
    • How many servers and how much bandwidth do I need to serve increasing populations of users?
    • How will I project future system needs?
    • What technology choices will cause scalability and performance problems?

    Attendees may be suprised to learn:

    • RPC-style SOAP calls can be 327% slower than document-style SOAP calls.
    • IBM WebSphere Web Services have scalability problems with large message sizes.
    • BEA WebLogic has interoperability problems with .NET.

    Biz Talk: Opportunities for Web Services in Developing Enterprise Portals

    With the hype surrounding web services, and the explosion of both acronyms and application complexity, this talk sheds some light towards understanding the practical implementation of the web services, specifically in the context of enterprise portals. As more and more organizations realize the importance of providing a unified dashboard of information, services and context, both within and outside the firewall, web services can play a fundamental role in creating a foundation that is both practical as well as functionally and technically scalable. This talk examines the implementation of web services in managing complex entitlement models, managing different information classification schemes from disparate sources, and realizing the benefits from key components of the web services model. The discussion is aimed at both business managers looking to understand the applicability, benefits and challenges of embracing web services as well as technical architects looking to create an architecture that leverages advancements in web services for practical problems.
