地域
地域（Region） 是腾讯云托管机房分布地区，地域下有不同的可用区。
例如：一个托管机房的地域是北京，可用区是北京一区。处于同一地域的云服务产品可以通过内网互通，不同地域云产品之间内网不互通，选择最靠近您客户的地域，可降低访问时延、提高下载速度。
读写分离
读写分离让主数据库（master）处理事务性增、改、删操作（INSERT、UPDATE、DELETE），而从只读实例（Read only Instance）处理 SELECT 查询操作。
可用区
指腾讯云在同一地域内电力和网络互相独立的物理数据中心。目标是能够保证可用区之间故障相互隔离，不出现故障扩散，使得用户的业务持续在线服务。
QPS/并发
QPS/并发指每秒请求的并发数，1QPS 即每秒同时支持请求接口1次，50QPS 即每秒同时支持请求接口50次。
数据库引擎
数据库引擎是用于存储、处理和保护数据的核心服务。利用数据库引擎可控制访问权限并快速处理事务，从而满足企业内大多数需要处理大量数据的应用程序的要求。 每个数据库实例均支持数据库引擎。
云数据库 Redis
云数据库 Redis（TencentDB for Redis）是基于腾讯云在分布式缓存领域多年技术沉淀，提供的兼容 Redis 协议、高可用、高可靠、高弹性的数据库服务。云数据库 Redis 兼容 Redis 2.8、Redis 4.0、Redis 5.0 版本协议，提供标准和集群两大架构版本。最大支持4TB的存储容量，千万级的并发请求，满足业务在缓存、存储、计算等不同场景中的需求。S
