Study Notes
System Design Fundamentals
- Reverse proxy forwards client requests to web servers and returns their responses to the client.
- Cache is a high-speed storage layer between the application and data source, reducing the need to access the original source for data.
- Caching occurs at multiple locations in a distributed system, such as client, DNS, CDN, load balancer, API gateway, server, and database.
- Data partitioning involves horizontal (sharding) and vertical partitioning of database tables to distribute load and enhance query performance.
- Database replication maintains multiple copies of the same database across servers to improve availability, redundancy, and fault tolerance.
- Replicated database configuration involves a primary (master) database and replicas (slaves) for synchronized data and advantages in performance, availability, protection, and load balancing.
- Distributed messaging systems enable reliable, scalable, and fault-tolerant message exchange between geographically-dispersed applications or components.
- Microservices organize applications as small, loosely-coupled, and autonomously deployable services, communicating via well-defined APIs.
- Microservices adhere to the Single Responsibility Principle, offer independence, decentralization, lightweight communication, and fault tolerance.
- NoSQL databases store unstructured or semi-structured data and are popular for their flexibility, scalability, and ability to handle large volumes of data.
- NoSQL databases can be categorized into document-based, key-value stores, wide-column stores, and graph databases.
- NoSQL databases are well-suited for modern applications, big data processing, and real-time analytics due to their ability to handle diverse and large datasets.
