Learning objectives

  • Explain Back-Pressure, Queuing Theory Basics, and Little's Law as an operational tradeoff problem spanning latency, throughput, resilience, and cost instead of one-dimensional scaling advice.
  • Use Back-Pressure, Queuing Theory Basics, and Little's Law to reason about bottlenecks, graceful degradation, and production-readiness choices before a system is under stress.
  • Use system-design-primer to connect the learner page to load patterns, capacity planning, reliability mechanisms, and performance budgets.

Prerequisites

  • Comfort reasoning about synchronous and asynchronous architectures, bottlenecks, and failure modes.

Source-of-truth note

This teaching unit is learner-facing guidance. Its canonical source backbone is the referenced book system-design-primer, and outside material should only clarify or strengthen that backbone.
