    - - Architecture style represents
      - One overall structure determined, rest are easy
      - Save costs and time
    - - It contains a set of rules, constraints, and pattern of the how to structure a system into a set of elements and connectors.
      - It governs runtime interaction of flow control and data transfer
      - An architecture style (architecture pattern) abstracts the common properties of a family of similar designs
