Everything about NoSQL Systems – Types, Benefits, and Real-World Uses
https://piaosanlang.gitbooks.io/mongodb/content/section1.1.html
NoSQL(NoSQL = Not Only SQL ),即"不仅仅是SQL",指的是非关系型的数据库。是对不同于传统的关系型数据库管理系统的统称。
https://www.youtube.com/watch?v=0buKQHokLK8
NoSQL databases can operate in multiple modes: as key-value store, document store or wide column store.
HTTP+
https://developer.mozilla.org/zh-CN/docs/Web/HTTP
超文本传输协议(HTTP)是一个用于传输超媒体文档(例如 HTML)的应用层协议。它是为 Web 浏览器与 Web 服务器之间的通信而设计的,但也可以用于其他目的。
缓存+
https://hackernoon.com/the-system-design-cheat-sheet-cache
The cache is a layer that stores a subset of data, typically the most frequently accessed or essential information, in a location quicker to access than its primary storage location.
https://www.youtube.com/watch?v=bP4BeUjNkXc
Caching strategies, Distributed Caching, Eviction Policies, Write-Through Cache and Least Recently Used (LRU) cache are all important terms when it comes to designing an efficient system with a caching layer.

RPC+
https://javaguide.cn/distributed-system/rpc/rpc-intro.html
为什么要 RPC ? 因为,两个不同的服务器上的服务提供的方法不在一个内存空间,所以,需要通过网络编程才能传递方法调用所需要的参数。并且,方法调用的结果也需要通过网络编程来接收。

This video is part of an 8-lecture series on distributed systems, given as part of the undergraduate computer science course at the University of Cambridge.
CAP+
https://www.hellointerview.com/learn/system-design/core-concepts/cap-theorem
Master the fundamental tradeoffs between consistency and availability in distributed systems.
https://www.ibm.com/think/topics/cap-theorem
The CAP theorem says that a distributed system can deliver only two of three desired characteristics:
consistency, availability and partition tolerance (the ‘C,’ ‘A’ and ‘P’ in CAP).
https://www.youtube.com/watch?v=BHqjEjzAicA
Paxos+
https://lamport.azurewebsites.net/pubs/paxos-simple.pdf
The Paxos algorithm for implementing a fault-tolerant distributed system has been regarded as difficult to understand, perhaps because the original presentation was Greek to many readers.
https://paxos.systems/
Paxos algorithms are a family of consensus algorithms (or protocols) that are used in distributed systems to achieve consensus in the presence of crash failures.
https://www.scylladb.com/glossary/paxos-consensus-algorithm/
Paxos is a family of protocols for solving the problem of consensus in distributed networks.

高可用+
https://redis.io/blog/high-availability-architecture/
A high available architecture is when there are a number of different components, modules, or services that work together to maintain optimal performance, irrespective of peak-time loads.
https://www.ibm.com/think/topics/high-availability
High availability (HA) is a term that refers to a system’s ability to be accessible and reliable close to 100% of the time.
