Why is redundancy important in a high-availability cluster?
What is high availability (HA)?
Understanding and determining data center redundancy, availability and reliability is a critical part of the holistic design process, and one that can significantly impact cost. However, there is often confusion surrounding these three factors.
Redundancy—having a secondary or backup component available to take over when a primary one fails—is an important part of a high availability system. Redundancy enables databases to remain available to users and applications even when a component isn’t functioning.
High availability means that the systems will always be available regardless of what happens. With redundancy, you may have to flip a switch to move from one server to the other, or you may have to power up a new system to be able to have that system available. High availability is generally considered to be always on, always available.
Aug 10, 2021 · In a nutshell, high availability implies there is no single point of failure. Everything from load balancer, firewall and router, to reverse proxy and monitory systems, is completely redundant at both network as well as application level, guaranteeing the highest level of service availability.
When comparing high availability vs redundancy, HA includes implementation of automatic failover in case of failure, whereas redundancy refers to removing points of hardware or software failures.

Learn the difference between high availability and redundancy in IT systems and how they contribute to business continuity. High availability means continuous operation without intervention, while redundancy means having backup components that can take over in case of failure.
High availability (HA) is the ability of a system to operate continuously for a designated period of time even if components within the system fail. A highly available system meets an agreed-upon operational performance level by eliminating single points of failure.
