Software Architecture – review article and youtube video and answer five short essay questions (1) READ ATTACHED Software Architecture: Central Concerns, Key Decisions PDF (2) WATCH YOUTUBE VIDEO LINK BELOW: FOLLOWING QUESTION IN SHORT ESSAY STYLE. This assignment will require you to watch Adrian Cockroft’s presentation Globally Distributed Cloud Applications at Net ix and to read Malan and Bredemeyer’s paper Software Architecture: Central Concerns, Key Decisions (also available on D2L). You may nd these slides made by Adrian Cockroft useful as well. QUESTION_1. (20 points) Malan and Bredemeyer (M&B) outline several important architectural decisions that need to be made for a system. They refer to the rst one as System Priority Setting which means that for complex systems an architect needs to decide where to excel. Based on Adrian Cockcroft’s presentation, what are the areas that Net ix has decided to excel in? Explain your answer. QUESTION_2. (20 points) Based on M&B’s notion of System Properties and Cross-Cutting Concerns, can you identify any cross-cutting concerns? Describe ONE of them. What evidence (reason to believe) do you have that this is cross-cutting? QUESTION_3. (20 points) In the past, Net ix required nearly all teams to exclusively use Java for service and compo- nent development (although there have been recent moves towards a polyglot ecosystem). Evaluate the requirement that all teams use Java from the perspective of M&B’s minimalist architecture principle. What are the advantages and disadvantages of a monolingual ecosystem? Why do you think Net ix is moving towards polyglot development? Do you agree with their decision? QUESTION_4. (20 points) Net ix was an early adopter of, and continues to embrace, the public cloud (Amazon AWS), whereas some companies like Apple & Dropbox are moving away from the public cloud. List at least three advantages of using the public cloud, and three reasons of moving away from the public cloud. Doyou agree with Net ix’s decision to remain with the public cloud (provide detailed reasoning)? QUESTION_5. (20 points) What was your most important take-away (i.e. lesson learned) from Cockcroft’s presenta- tion?
