Analyzing Requirements and Service Selection Questions
Given a business requirement (e.g., 'store real-time game data with sub-millisecond latency'), systematically identify appropriate cloud services and justify your choice based on performance, cost, and operational considerations. Articulate trade-offs explicitly.

Given strict cost constraints, outline a simple decision matrix you would use to select between several cloud services for a low-latency feature. Describe axes, weighting approach, example scoring criteria for performance, cost, operational complexity, and how to present results to stakeholders.

How would you build a benchmarking and load-testing suite to validate a candidate cloud service's sub-millisecond latency claims? Describe the test harness architecture, traffic shaping, network emulation, statistical analysis approach, and how to ensure repeatable results.

Build a three-year ROI and total cost of ownership model to justify selecting a managed cache that is 30% more expensive but reduces operations headcount by 70%. Identify assumptions, direct and indirect cost categories, intangible benefits, and how you would defend non-monetary arguments to a CFO and CTO.

For a global user base requiring sub-millisecond leaderboard reads, propose a replication and routing strategy that covers read/write locality, replication lag, conflict resolution, and cost. Discuss geo-primary, active-active, and read-replica options and justify your recommended approach.

You must choose between a managed Redis service and custom in-memory servers on VMs for sub-millisecond latency. Create a decision framework that quantifies performance, operational burden, TCO, high availability, feature differences (clustering, persistence), and migration paths, then apply it to a simple example.
