Software Systems Fault Tolerance. Software fault tolerance is the ability for software to detect and recover from a fault that is happening or has already happened in either the software or hardware in the system in which the software is running to provide service by the specification. Both schemes are based on software redundancy assuming that the events of coincidental software failures are rare.
Fault-tolerant software assures system reliability by using protective redundancy at the software level. A definition of fault tolerance with several examples. Although building a truly practical fault-tolerant system touches upon in-depth distributed computing theory and complex computer science principles there are many software toolsmany of them like the following open sourceto alleviate undesirable results by building a fault-tolerant system.
The term essentially refers to a systems ability to allow for failures or malfunctions and this ability may be provided by software hardware or a combination of both.
Tools for building a fault-tolerant system. What is Software Fault Tolerance. With any component failure is not fault tolerant. Software fault tolerance is the ability for software to detect and recover from a fault that is happening or has already happened in either the software or hardware in the system in which the software is running in order to provide service in accordance with the specification.
