How does a Multi CDN solution aim to address CDN outage risks?

Question

A Multi CDN solution fundamentally aims to mitigate the risks associated with Content Delivery Network (CDN) outages by employing a strategy of simultaneous utilization of multiple CDN providers. The core principle is to distribute content delivery across a diverse network of servers managed by different vendors. This approach is designed to enhance both the speed and reliability of content delivery. By leveraging services from various providers, such as Akamai, Fastly, and others, organizations can create a more resilient infrastructure.

Accepted Answer

The primary objective of this distributed model is to prevent a single point of failure. In the event that one CDN provider experiences an outage, whether due to technical glitches, misconfigurations, or external factors like cyberattacks, a Multi CDN setup can automatically reroute traffic to an alternative, operational CDN. This seamless transition ensures that end-users experience minimal to no interruption in service. For instance, during the widespread Fastly outage on June 8th, 2021, which affected major platforms like Spotify and Netflix, users leveraging a Multi CDN solution through platforms like Mlytics were unaffected. Mlytics' Smart Load Balancing feature, for example, detected the performance degradation and outage of Fastly and automatically shifted user requests to other available CDNs, such as Akamai in certain regions, thereby maintaining service continuity.
