Load balancing is the process of distributing incoming network traffic or computational workload across multiple servers or resources to ensure no single server becomes overwhelmed. It's necessary for several reasons:
Improved availability: If one server fails, others can continue serving requests
Better performance: Distributes load to prevent server overload and reduce response times
Scalability: Allows adding more servers to handle increased traffic
Resource utilization: Ensures efficient use of all available servers Think of it like having multiple checkout counters in a store instead of just one - customers get served faster and if one counter breaks down, others are still available.
