What are High Availability Cluster Solutions for Windows?

High availability cluster solutions are systems designed to ensure continuous operation of applications and services by minimizing downtime through redundancy and failover mechanisms. These solutions link multiple servers or nodes to work together, so if one node fails, others automatically take over without service interruption. They provide monitoring, load balancing, and automatic recovery features to maintain system reliability and performance. High availability clusters are critical for mission-critical applications requiring near-zero downtime, such as databases, web services, and financial systems. By reducing single points of failure, they help organizations meet stringent uptime and disaster recovery requirements.
