Load Balancing

Zero-downtime deployments and multi-cloud reliability

Cloudflare Load Balancing ensures you never lose revenue to downtime again. Our load balancing product directs traffic across your servers, data centers, and cloud environments based on server health and user-to-origin latency, with near-instantaneous global failover.

Truly Cloud Agnostic

Unlike cloud-native load balancers that favor their own ecosystem, Cloudflare Load Balancing is vendor-neutral. Developers can seamlessly balance traffic between AWS, GCP, Azure, and on-premise servers.

Faster Health Checks

We monitor origin health from multiple points across our global network. Our checks can spot connectivity issues from the rest of the world and fail over faster and more reliably.

Integrated Stack

Load Balancing works natively with the rest of Cloudflare's stack. Route traffic with Argo for performance, protect origins with the WAF, and gain insights from a single control plane.

Intelligent traffic routing across clouds

Load Balancing prevents application downtime and performance degradation by intelligently routing traffic away from unhealthy or overloaded origin servers, ensuring users are always sent to the fastest, most available location. Build highly available and performant multi-cloud or multi-region applications without having to manage complex networking hardware or write fragile, custom failover scripts.

Lawrence Berkeley National Laboratory

Lawrence Berkeley National Laboratory replaced on-prem hardware appliances with Cloudflare Load Balancing, removing a single point of failure and improving uptime across thousands of web servers.

Powerful primitives, seamlessly integrated

Built on systems powering 20% of the Internet, Load Balancing runs on the same infrastructure Cloudflare uses to build Cloudflare. Enterprise-grade reliability, security, and performance are standard.
