high availability. High availability refers to a system’s ability to avoid loss of service by minimizing downtime. It’s expressed in terms of a system’s uptime, as a percentage of total running time.

First published on MSDN on Oct 05, 2010 When evaluating how to increase availability and reduce downtime for your deployments, solutions can commonly be categorized as either a 'High Availability' solution or a 'Fault Tolerant' solution.

Explore how routing in networks can be made more fault tolerant thanks to redundant The availability of multiple paths increases the redundancy of a network.

Achieving a network uptime of 99.999% (commonly referred to as “five nines”, which equates to 5.26 minutes of downtime) should be your organization’s goal. Unlike with fault tolerant systems, there will always be some amount of downtime with high availability, even if it is only a few seconds. 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.

This is where fault tolerance comes in. Fault tolerance is a feature of high availability; in other words, you first configure high availability and then layer on the fault tolerance capability.

Fault Tolerance and High Availability - Resource Library. Big Data High Availability vs Fault . The difference between fault tolerance and high availability,is this: A fault tolerant environment has no service interruptionbut a significantly higher cost, while a highly available environmenthas a minimal service interruption. Fault tolerance relies on specialized hardware to detect a hardwarefault and instantaneously switch to a redundant hardware component—whetherthe failed component is a processor, memory board, power supply, I/Osubsystem, or storage subsystem. It’s down to you as to the level of High Availability or Fault Tolerance you want to implement, and this really depends on the business impact it would have when components begin to fail, and do bear in mind, it’s not if a failure occurs, it’s when a failure occurs. A Fault Tolerant system is extremely similar to HA, but goes one step further by guaranteeing zero downtime. HA still comes with a small portion of downtime, hence the ideal of a perfect HA strategy reaching “five nines” rather than 100% uptime.
