High Availability Systems

High availability systems are designed to ensure that services remain operational without interruption, even in the face of failures. They achieve this through redundant components, such as extra servers or network connections, so that if one part fails, others can take over seamlessly. This is crucial for applications where downtime can lead to significant losses, such as banking or online services. By implementing strategies like load balancing and real-time backups, high availability systems aim to provide continuous access and reliability, ensuring users can always access the services they need.
