Difference between Failover and High-availability cluster

Failover vs. High-availability cluster

In computing and related technologies such as networking, failover is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application, server, system, hardware component, or network. High-availability clusters (also known as HA clusters or fail-over clusters) are groups of computers that support server applications that can be reliably utilized with a minimum amount of down-time.

Similarities between Failover and High-availability cluster

Failover and High-availability cluster have 7 things in common (in Unionpedia): Application software, Computer, Computer network, Heartbeat (computing), High availability, Redundancy (engineering), Server (computing).

Application software

An application software (app or application for short) is a computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user.

Heartbeat (computing)

In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system.

High availability

High availability is a characteristic of a system, which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.

Redundancy (engineering)

In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.

Server (computing)

In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".

Failover and High-availability cluster Comparison

Failover has 25 relations, while High-availability cluster has 40. As they have in common 7, the Jaccard index is 10.77% = 7 / (25 + 40).
