# Elastic Load Balancer
#aws-service
- A load balancer allows you to evenly distribute traffic to multiple servers in one or more datacenter.
- If a datacenter or server becomes unavailable (unhealthy) the load balancer will route the traffic to only available datacenters with servers.
Running your workload across multiple Availability Zones ensures that if 1 or 2 AZs become unavailable your service / applications remains available.
