Information System Architecture (Subject) / 03 - Distribute Systems (Lesson)

Front side advantages and disadvantages of distributed systems
back

advantages

  • Shared use of resources (printer, files, memory, ...)
  • Openness: Possibility to add proprietary resources (from different manufacturers)
  • Parallelism: Different processes can be executed on different processors at the same time
  • Scalability: Increasing the performance of the system by adding components
  • Fault tolerance: Tolerance of hardware and software failure through the use of alternative hardware and software components
  • Transparency: User does not need to know the distribution
  • Low costs (PC, LAN)

disadvantage

  • Complexity: High development effort and development risks, high maintenance effort, understanding difficult for users
  • Security: Accessibility difficult to control. "Listening in" to the data exchange is possible. Management of security therefore difficult.
  • Manageability: Different hardware and software manufacturers in different versions, high maintenance costs
  • Unpredictability: Predicting the behavior of a distributed system is difficult. Load distribution of the system cannot be foreseen or is difficult to determine
