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?
