Azure Front door caching VS Azure CDN for blob storage

This is regarding usage of Azure Front Door caching and Azure CDN. I have a Azure static website that will displaying the data (mainly office files and videos) from Azure blob storage. The files in blob storage will rarely change. I am looking for the best way and cheapest way to cache these files, so that files can be fetched quickly.

Recommendation or supporting links will be helpful.

Thanks in advance.

Caching static website content is a technique to improve user experience as well as reducing the load on webservers by offloading the delivery of static content to a dedicated cache service.

Azure CDN:

• Azure CDN is globally distributed network of servers that can deliver content to the customers in a very large scale.
• It is a video streaming platform where videos are delivered based on the customer’s nearest edge location.
• Azure CDNs stores cached content on the edge servers which results in minimizing network latency.

Azure Front door:

• It provides Scalable, secure and fast delivery of your global applications .
• It enables you to define, manage, and monitor the global routing for your web traffic.
• It provides best performance and instant global failover for high availability.

Based on your scenario, that best caching you can use is Azure CDN due to the following:

• Azure CDN is best for delivering static content like Videos, Images and PDFs whereas Azure Front Door is for delivering sites, services and APIs.
• Azure CDN is cost-effective whereas Azure Front Door charges per ruleset.
• Azure CDN does all the functionality similar to Azure Front Door.
• Azure CDN performs a good job at content delivery at a cheaper price!.

Update: As suggested by @silent, you can also make use of Azure Front Door Standard which is a combination of classic CDN and Front Door.
