Large Scale System Architecture for Developer Platforms Questions

Practice designing scalable systems that serve thousands or millions of API calls or developer interactions. Understand how to partition the design: API gateway layer, business logic layer, data layer. Discuss scaling strategies: adding replicas, distributing load, isolating traffic types. Know when to add components like caches (Redis), message queues (Kafka), CDNs, and how they affect latency and cost. For developer platforms specifically, consider onboarding experience, quota management, rate limiting, multi-tenancy isolation.
