What Is A Failover Cluster? Types And Examples
ServerWatch, Tuesday, October 31,2023
A failover cluster is essentially a redundant, performance-optimized backup system for digital architectures. When a group of two or more independent servers is designed to work together with the purpose of providing a robust backup structure; better balancing workloads; ensuring integrity and reliability of applications, systems, or services; and providing scalability and availability, it is considered a failover cluster.
Failover clusters are used heavily by industries that need to run mission-critical applications, systems, and services. Here's a look at how the tech works, the different types of failover clusters, their challenges, and practical applications.
Failover cluster types
There are two main types of failover clusters, high availability (HA) and continuous availability (CA), but there are other options as well, especially for hybrid failovers combining virtual and physical infrastructure.
