The below content is presented so you can quicly understand Office365 CDN and execute the related commands and start enjoying the benefits of the CDN feature in your SharePoint Online environment.
Problem
There are a couple of problems if third party libraries such as moment.js, datatable.js, lodash.js, ag-grid.js and many more are used. These libraries are maintained in each site collection because there are different sets of users and permissions granted only to respective departments. With permission restriction, it is not possible to share the files across site collections.
Approaches
- Separate site collection can be provisioned and common libraries can be accesed and maintained.
- Buy an Azure CDN storage and maintain common assets - extra cost to maintain.
- In-built SharePoint Online CDN which was proposed by Microsoft and current available in SharePoint Online environment.
Since SharePoint Online CDN (Office365 CDN) is currently avaible, I have complied the list of features and PowerShell commands to start enjoying :)
