What is High Availability?
FAQs
What is high availability?
High availability means that points of failure are eliminated so that should one of those components go down, the application or system can continue running as intended.
What is a high-availability cluster?
High-availability clusters are groups of servers that work together as one system. While these servers share storage, they're on different networks.
How does high availability work?
High availability requires points of failure to be eliminated, the establishment of reliable redundancy through duplication of components, the implementation of mechanisms for easy detection and resolution of system failures, and the efficient routing of traffic across systems or servers using load balancers.
Why is high availability important?
High availability is important to maintain data availability, prevent data loss, and ensure that applications run smoothly for users as expected — especially when it comes to mission-critical systems.
