CDN Provisioning lets you automatically route your web traffic to the fastest CDN provider in a user’s region. Using Multi-CDN improves speed and uptime, reduces latency, and helps SEO for your domain. This tool can be configured to make decisions based on synthetic monitoring or real-user monitoring (RUM). This tutorial walks you through the process of setting up Multi-CDN using RUM.
Common Use Cases for Multi-CDN with Real-user Monitoring (RUM)
RUM is best suited for organizations that want long-term data trends based on real usage patterns. Using our RUM script provides you with real-user monitoring from our extensive community and your actual users. This data allows for even smarter routing decisions as it is based on your users’ behavior and not simulated data.
