BYO CDN - Bring Your Own CDN

By default, BlendVision One will handle the delivery of content created within our platform, however, we also offer the flexibility of BYO CDN-Bring Your Own CDN which enables you to leverage your AWS CloudFront distributions for content delivery within BlendVision One. You will configure AWS CloudFront distributions with the origin and cache behavior policies that BlendVisione One provides and complete the settings accordingly. 

This guide will walk you through the setup and configurations of integrating your own CDN.
