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.

Design an architecture that supports sub-millisecond gameplay reads and also real-time analytics for leaderboards and telemetry. Describe streaming ingestion, materialized views for the hot path, storage tiering for analytics, and how to keep analytics and hot-path data synchronized without impacting latency.

Identify and estimate the main cost drivers for running an in-memory cluster providing sub-ms reads across three regions. Propose concrete optimization strategies such as right-sizing, reserved capacity, multi-tier caching, and cross-region replication trade-offs to reduce cost while meeting SLOs.

Prepare an outline for a stakeholder slide that compares DynamoDB+DAX, ElastiCache Redis, and self-hosted Redis for sub-millisecond leaderboards. What quantitative metrics and qualitative factors should be shown, and how would you form a clear recommendation?
