容错需要高可用性吗?
我仍然将高可用性原理与容错的原则混淆。我研究了每个定义的定义,最终得到了以下答案:
- 容错是指没有故障点的系统。
- 高可用性是指额外的停机时间最小的系统(高达99.999%的正常运行时间)
,我从SNIA词典中发现,通过失败的公差通常可以实现高可用性。那么,这是否意味着容错系统肯定可以提供高可用性?
I still confuse the principle of high availability with that of fault tolerance. I have researched about the definition of each and ended up with the following answers:
- Fault tolerance refers to systems that have no point of failure.
- High availability refers to systems with minimized downtime (up to 99.999% uptime)
Additionaly, I found from the SNIA dictionary that high availability is most often achieved through failure tolerance. So, does this mean that a fault tolerance system can definitely provide high availability?
