Can you explain the concept of load balancing in backend application deployment?
Load balancing is a technique used in backend application deployment to distribute incoming network traffic across multiple servers. It helps to ensure that no single server is overwhelmed with requests, thus improving the overall efficiency and scalability of the application. Load balancers act as intermediaries between the client and the servers, intelligently routing requests to the least loaded server in a balanced manner. This allows for better resource utilization and prevents bottlenecks. By distributing the load across multiple servers, load balancing also provides fault tolerance and high availability, as it can redirect traffic to healthy servers in case of failures. Overall, load balancing is a critical component in ensuring the optimal performance and reliability of backend applications.
