Architecture of Distributed Systems Homework Assignment 1 R. H. Mak

Exercise Consider the models on the following slides and answer the following questions. Each model is provided with a hyperlink to acknowledge its source and for additional information. What building blocks do you see? What do they represent? Are they conceptual (C) or physical (P)? Same questions as 1, but now for connectors? Do not forget (C) or (P)! To which views (1..*) does the model belong? Motivate why, and identify corresponding stakeholders and their concerns. Which of the following EFRs are addressed (Y + motivation | N)? Performance/scalability, availability/reliability, security, maintainability, other? Is there a concept of distribution (Y + motivation | N)? Comment on the clarity/semantics of the diagram  |  |  , plus motivation Keep you answers crisp! Rudolf Mak 9-May-19
