System Design Notes
High-level architecture, scalability, caching, and microservices.
System Design Basics
System design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements.
Key Concepts
- Scalability: The capability of a system to handle a growing amount of work. (Horizontal vs Vertical scaling).
- Latency vs Throughput: Latency is the time to perform some action. Throughput is the number of such actions executed per unit of time.
- CAP Theorem: Consistency, Availability, Partition Tolerance.
- Load Balancing: Distributing traffic across multiple servers.
- Caching: Storing frequently accessed data in memory (Redis, Memcached).
