Now redundancy and fault tolerance means that we’re going to need to have redundant hardware components. VMware Fault Tolerance differs from the concept of high availability due to its capability in maintaining virtually no disruption to applications in the wake of a failure. A highly available system can prevent downtime, but if a node is lost, there is a delay in restarting its applications on another node in the same cluster.

HA redundancy provides 1:1 event broker sparing to increase overall service  Aug 31, 2018 In this post we'll look at the strategies for fault tolerance, consistency and high availability (HA) and the trade-offs each strategy makes.

Now, let’s look at Fault Tolerance, which expands on High Availability to offer a greater level of protection should components begin to fail in your infrastructure, however, there are usually additional cost implications due to the greater level of resiliency offered. Think of fault tolerance as high availability's older brother. Fault tolerance means that a system will almost always maintain uptime — and users will not notice anything different during a primary system outage.
