What is fault tolerance architecture?

Fault tolerance refers to the ability of a system (computer, network, cloud cluster, etc.) to continue operating without interruption when one or more of its components fail.

What is fault tolerance vs High Availability?

The difference between fault tolerance and high availability, is this: A fault tolerant environment has no service interruption but a significantly higher cost, while a highly available environment has a minimal service interruption.

How do you architect a design that is fault-tolerant?

You can achieve fault-tolerance by introducing redundancy into your system and by decoupling the parts of your architecture such that one side does not rely on the uptime of the other.

How do you calculate fault tolerance?

Here, fault-tolerance is calculated as f = m/n, where m is number of tolerable subsystem failures and n is number of available subsystems. The performance/cost rating is given by p = (S + R + C)/3, where S is performance speed, R is recovery time rating, and C is the cost mea- sure.

What is fault tolerance?

Fault tolerance is a process that enables an operating system to respond to a failure in hardware or software. This fault-tolerance definition refers to the system’s ability to continue operating despite failures or malfunctions.

What is difference between fault tolerance and fault resilience?

Fault Tolerance: any user of the service does not observe any fault (observing delays is normal). Fault Resilience: a fault may be observed, but only in uncommitted data (like the database may respond with an error to the attempt to commit a transaction, etc.).

What is meant by fault tolerance?

What is the difference between fault tolerance and resilience?

What is fault tolerance in computer science?

Why do we need fault tolerance?

The goal of fault tolerant computer systems is to ensure business continuity and high availability by preventing disruptions arising from a single point of failure. Fault tolerance solutions therefore tend to focus most on mission-critical applications or systems.
