CDN Provisioning lets you automatically route your web traffic to the fastest CDN provider based on user location. Using Multi-CDN improves speed and uptime, reduces latency, and helps SEO for your domain. Our Multi-CDN 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 synthetic monitoring.
Note: For RUM monitoring, please visit our How to Setup Multi-CDN Using RUM tutorial.
Common Use Case for Multi-CDN Synthetic Monitoring in Constellix
Using synthetic monitoring with your Multi-CDN configuration lets you take advantage of simulated user data collected from data centers and global monitoring nodes. While not based on your exact users like RUM, synthetic monitoring provides valuable insight that you can use to make smarter routing decisions for your domain. This type of monitoring is best for organizations that would like short-term data for troubleshooting performance issues. Synthetic monitoring is also a great solution for smaller businesses, as it allows you to gather data from the Constellix community instead of just the data from users visiting your site.
