Agenda l.jpg
Agenda

  • What is a Virtual Organization?

  • Why VOs?

  • The challenges of dynamic VOs

  • Risk Management

  • TrustCoM Framework and Architecture

  • Discussion


Virtual organizations l.jpg
Virtual Organizations

A temporary or permanent coalition of autonomous organizations that pool resources, capabilities and information to achieve common business objectives.

  • Characteristics

    • ad-hoc partnerships

    • (ideally) highly dynamic

    • based on process integration

    • use IT as a means for coordination


What a vo is good for l.jpg
What a VO is good for

  • optimize use of opportunities which derive from market and/or resources

  • reduce transaction costs

  • collectively offer services to customers that could not be provided by the individual enterprises.


How dynamic can a vo be l.jpg
How Dynamic can a VO be?

  • Current VOs are rather static

  • Dynamic VOs are hard to manage and have high risk profiles

  • IT, by itself, is no silver bullet

    • It is not enough to synchronize business processes

  • Keys:

    • self-management, to cope with complexity

    • risk management, so that the benefits can overcome the risks


Risk management l.jpg
Risk Management

  • Risk attenuators

    • Trust

    • Trust substitutes

      • SLA contracts and monitoring

      • Authorization policies

      • Accountability

      • Reputation

Goal: strike a balance between trust and its substitutes

Trustcom framework l.jpg
TrustCoM Framework

  • A framework for trust within a service oriented architecture

  • Encapsulates trust, security and contract components

  • Separates self-management from the application-level

  • Permits independent risk analysis

Status l.jpg
Status

  • First implementation of main services in each subsystem (Infrastructure, Policy, SLA, Trust, VO and Business Process Management)

  • WS-* interop profiles for the TrustCoM Framework (XACML, SAML, WSLA, WS-CDL)

  • Test-bed scenarios (Collaborative Engineering)


Conclusions l.jpg
Conclusions

  • Risk and self-management are the key enabling factors for Dynamic VOs

  • Self-management is achieved using automatic monitoring and reconfiguration policies.

  • Riskis reduced using trust and trust substitutes (e.g. contracts, security policies and reputation measures).

  • TrustCoM is putting these ideas into practice.
