Load Balancers
Web3 / infrastructure applications
Load balancers are infrastructure components that distribute incoming network traffic and computational requests across multiple blockchain nodes to prevent any single node from becoming overwhelmed. They operate at the network layer, directing API requests, transaction submissions, and block queries to available nodes based on current capacity, latency, and health status. Load balancing improves system responsiveness, maximizes network resource utilization, and ensures graceful degradation when individual nodes experience issues. Modern blockchain infrastructure often employs intelligent load balancers that understand blockchain-specific protocols to route requests optimally. Example: Infura operates load balancers that distribute millions of daily requests from Ethereum users across hundreds of backend nodes, ensuring consistent service availability while handling traffic spikes during periods of high network activity or market volatility. Why it matters for blockchain infrastructure: Load balancers ensure that blockchain networks remain responsive under high demand, preventing service degradation that could impact user experience during critical market events. They enable infrastructure providers to scale horizontally by adding nodes rather than upgrading individual servers.
