OFFICE 365 CDN:-

Now you can use the Office 365 content delivery network with SharePoint Online. Microsoft introduced this concept in Office 365 of public and private CDNs.
Office 365 allows you to serve content publically so that you could host your static content like images into a CDN. This content may consist of things such as images, CSS and JavaScript.
The CDN works as a geographically distributed caching proxy, by caching assets closer to the browsers requesting them.
You can easily set one up and start storing your static files in these CDNs.
1. Public CDNs can host basically any type of asset you want to store
2. Private CDNs can host
• IMG/LINK/CSS urls in classic publishing pages
• Content Search Webpart Display Templates + Images from Query results
• Picture Library Slideshow Webpart URLs
• Image Fields from REST API calls
• SharePoint Image Renditions
