Eliminating hardware with Load Balancing and Cloudflare One

In 2023, Cloudflare introduced a new load balancing solution supporting Local Traffic Management (LTM). This year, we took it a step further by introducing support for layer 4 load balancing to private networks via Spectrum. Now, organizations can seamlessly balance public HTTP(S), TCP, and UDP traffic to their privately hosted applications. Today, we’re thrilled to unveil our latest enhancement: support for end-to-end private traffic flows as well as WARP authenticated device traffic, eliminating the need for dedicated hardware load balancers! These groundbreaking features are powered by the enhanced integration of Cloudflare load balancing with our Cloudflare One platform, and are available to our enterprise customers. With this upgrade, our customers can now utilize Cloudflare load balancers for both public and private traffic directed at private networks.
