Explanation
Load balancing distributes incoming traffic across multiple servers, meaning if one server fails, others continue serving requests - providing high availability. It also scales horizontally by simply adding more servers behind the load balancer as demand grows, making it highly elastic. Server virtualization improves resource utilization but doesn't directly provide high availability by itself. An Active-Passive cluster provides failover but the passive node sits idle, wasting capacity and not easily scaling. RAID 6 provides disk-level fault tolerance for storage, not application-level availability.
