Cloud load balancing distributes incoming traffic across multiple resources such as servers, containers, services, or regions. It helps prevent one resource from becoming overloaded.

Why load balancing matters

Load balancing improves availability, performance, scaling, and fault handling. If one backend becomes unhealthy, traffic can be sent to healthy resources instead.

Load balancing and high availability

Load balancers are often part of high availability design, especially when paired with multiple availability zones.

In simple terms, load balancing keeps traffic from piling up in one place.
