# Load balancers > Load balancers spread incoming traffic across several servers, so a service stays up and responsive. Source: https://infranest.io/docs/load-balancers Last updated: 2026-09-18 --- Load balancers help keep your services fast and available by spreading incoming traffic across several servers, so no single server gets overwhelmed. ## Overview - A load balancer sits in front of your servers and routes incoming traffic to them. - If one server is busy or unavailable, traffic can go to another, helping keep your service up and responsive. - You control which ports the load balancer listens on, which servers it sends traffic to, and how it decides where to send each request. ## Manage load balancers 1. Go to **Load Balancers**. 2. Manage a load balancer's services (which ports it listens on and forwards to), its targets (the servers behind it), and its balancing method. ![Load balancers](/media/7939d6a9-a2b9-4cce-92de-1788b95969e8)
