How do Mid Servers in a Failover Cluster operate?

Mid Servers in a failover cluster operate independently without load balancing. This means that while each Mid Server in the cluster can handle tasks, they do not share the workload among themselves in a load-balanced manner. In a failover scenario, one Mid Server takes over the responsibilities of another if it goes down, ensuring continuous service. However, they function independently in normal operation, meaning they process their assigned tasks without distributing them across the servers.

This model is especially important in environments where consistent and reliable data collection is critical. Implementing a cluster in this way allows for a straightforward recovery process where an active Mid Server can take over for a failed one seamlessly, without the added complexity of balancing tasks in real-time. This independent operation simplifies management and helps maintain operational stability within the Discovery process.
