Sintel Apps Content Delivery Network CDN

What is a Content Delivery Network (CDN)

A Content Delivery Network (CDN) is a global network of servers that stores copies of website content (like images, videos, and code) in locations worldwide, delivering it from a server nearest to the user. This improves website loading speed, reduces latency, and handles traffic spikes. It makes the users experience faster and more reliable.

Sintel CDNs

In Sintel we use 2 CDNs as follows:

• https://app.sintelapps.com (to support legacy Sintel Forms)
• https://cdn.sintelapps.com (to support Sintel Apps and Sintel BI)

Why we use them

1. SPFx is designed to load bundles from a CDN (SharePoint’s own App Catalog CDN or any HTTPS CDN).
2. Facilitates much easier and faster rollouts of critical updates, fixes and features.
3. Improves performance, reliability, scalability, and long-term maintainability of SharePoint Online solutions.
4. Offloads traffic from SharePoint Online.
5. As we release new features regularly, a CDN ensures customers are always using the latest version of our products without having to continously check for updates and manually apply them.
6. Using a CDN for SPFx assets is considered best practice.

What our CDN contains

Our CDN contains the latest versions of the following items used in our products:

1. Javascript files
2. Fonts
3. Icons

Our products are typically SPFx packages and each package contains a complete application including the required Javascript files, fonts and icons. When using our products they can verify if the version of the files a customer is using is the latest version and if not the latest version will be pulled from the CDN. This ensures that customers are always using the latest version of our products and have access to all product features.

About our CDN

1. Our CDN does not provide public write access and only our deployment process can save to our CDN.
2. Our CDN only supports HTTPS Endpoints.
3. Our CDN uses Microsoft Defender for Cloud with alerting.
4. Our CDN is compliant with Microsoft’s publisher/security requirements and our apps that leverge it are approved and published on the Microsoft Marketplace (formerly AppSource).
