Scalability

Explain different caching strategies (e.g., cache-aside, read-through, write-through, write-behind) and their trade-offs. Discuss distributed caching with tools like Redis.

Discuss horizontal vs. vertical scaling. Explain patterns like load balancing, database read replicas, and database sharding.

Practice designing systems (e.g., URL shortener, Twitter feed). For each, start by defining key non-functional requirements like scalability, availability, latency, consistency, and cost, then discuss the trade-offs of your design choices.
