  1. Distributed Systems: The Overall Architecture Chapter 5 Information Systems Management In Practice 6E McNurlin & Sprague

  2. Introduction Architecture vs. Infrastructure

  3. Attributes of Distributed Systems • Processing is distributed • Processors are interconnected • Databases are distributed • System-wide rules provide the operating discipline for the components to work together

  4. When to Distribute • Operations are interdependent • Businesses are homogenous • Corporate culture dictates centralization of some functions

  5. Two Guiding Frameworks

  6. Seven Types of Distributed Systems • Host-Based Hierarchy

  7. Seven Types of Distributed Systems • Decentralized Stand-Alone Systems

  8. Seven Types of Distributed Systems • Peer-to-Peer LAN-Based Systems

  9. Seven Types of Distributed Systems • Hybrid Enterprise- wide Systems • CASE EXAMPLE: Northwest Airlines

  10. Seven Types of Distributed Systems • Client-Server Systems

  11. Seven Types of Distributed Systems • Internet-Based Systems

  12. Seven Types of Distributed Systems • Internet-Based Systems • Server-Based Computing • CASE EXAMPLE: 3i • Peer-to-Peer Computing

  13. Seven Types of Distributed Systems • Web Services

  14. Seven Types of Distributed Systems • Web Services • The Significance of Web Services • CASE EXAMPLE: GM

  15. Defining the Overall IT Architecture • The Job of the Chief Technology Officer • CASE EXAMPLE: FMC Corporation • CASE EXAMPLE: The SABRE System

  16. Importance of IT Infrastructure

  17. Importance of IT Infrastructure Three Views of Infrastructure: • As a utility • As dependent • As enabling • CASE EXAMPLE: City of Sunnyvale
