Foundations of System Design

Beginner18 hours9 sections40 lessonsRated 5.0 out of 5 from 29 ratings

Develop a system design from requirements and runtime fundamentals through networks, coordination, storage, security, and scaling. Worked examples and practice questions connect each design choice to its assumptions, costs, and failure behavior.

What you will be able to do

  • Turn a product need into functional and non-functional requirements with measurable targets.
  • Reason about networks, APIs, ordering, and consistency when components communicate.
  • Choose storage, replication, and partitioning from access patterns and failure behavior.
  • Weigh caching, queuing, replication, and sharding against workload and operational cost.

Who this course is for

Engineers new to system design who want the vocabulary and trade-offs behind distributed services before working full interview cases.

Helpful to know first

  • No system design background is required; having written a small program is enough.
