Windows Server Failover Clustering
Windows Server Failover Clustering (WSFC) is a high-availability feature in Windows Server that groups multiple servers into a cluster to provide redundancy and failover capabilities for applications and services. It ensures continuous operation by automatically moving workloads from a failed node to a healthy one, minimizing downtime. WSFC is commonly used for critical services like databases, file servers, and virtual machines.
Developers should learn WSFC when building or maintaining enterprise applications that require high availability, such as SQL Server databases, Hyper-V virtual machines, or file shares, to ensure business continuity and disaster recovery. It is essential in environments where downtime is unacceptable, such as financial systems, healthcare applications, or e-commerce platforms, as it provides automatic failover and load balancing.
