Lecture 1: Concepts & Architectures (Attributes (Transparency…

- - - - CPU
      - Memory
      - Volatile data
- - - - Detecting (identifying components & (perhaps) reason
      - Marking failures (making visible to orthers)
      - Tolerating failures
      - Setting up redundancy
    - - Well-chosen & qualified architecture
      - Nodes in DS perform well (few SW bugs)
      - Redundancy & fail-over mechanisms
  - - - -# of users & processes, restricted by memory & computing power
      - Physical distance between nodes
      - The domain level
    - - Use asynchronous communication, separate handler
      - Keep info local, not distribute -> minimal latency
      - cache as much as possible
      - Organize data hierarchical (DNS)
      - Reduce name lookups for resources, use algorithmic scheme
      - Move computation to clients
