Is Azure CDN push or pull?

In the context of a content delivery network, Azure CDN is a pull based CDN. This means that Azure CDN automatically fetches or pulls your content from the origin server when it’s requested by users, rather than requiring you to manually push content to the CDN.

How does a CDN work in Azure?

A Content Delivery Network (CDN) in Azure is a globally distributed network of servers that efficiently delivers web content to users. CDNs store cached versions of these contents on edge servers situated closer to the end-users, which results in reduced latency and improved loading times.

In the context of Azure, the CDN works as follows:

1. Content Creation: The content creator uploads the original content (such as images, videos, or other static files) to a storage service like Azure Blob Storage or an Azure Web App.

2. CDN Configuration: The creator configures a new Azure CDN profile and creates a CDN endpoint linked to the origin server (where the content is stored). This configuration process involves selecting a provider (such as Microsoft, Akamai, or Verizon), setting up custom domains and SSL certificates, and configuring caching rules.

3. Caching Content: The first time a user requests specific content, the Azure CDN retrieves it from the origin server and then caches it on the nearest edge server. This cache may be refreshed or purged based on the TTL (Time to Live) settings or any custom caching rules set by the creator.

4. Content Delivery: When a user requests the same content again, the request is routed to the geographically closest edge server. If the content is available in its cache, the server delivers it with reduced latency. If it’s not available, the edge server fetches it from the origin server, caches it, and then delivers it to the user.

By leveraging Azure CDN, content creators can benefit from improved performance, global reach, and scalability. This ensures a better experience for end-users and lowers the load on the origin server.

Which is better front door Azure or CDN?

When comparing Front Door Azure and Content Delivery Network (CDN), it’s essential to understand their specific use cases and features to determine which one is better for your needs.

Front Door Azure is a global, scalable entry point that uses the Microsoft global network to improve web application performance, security, and reliability. It offers capabilities such as load balancing, URL-based routing, SSL offloading, and Web Application Firewall (WAF). Front Door is best suited for optimizing dynamic content delivery, multi-region load balancing, and securing applications against various threats.

On the other hand, Content Delivery Network (CDN) is a system of distributed servers that deliver static content such as images, stylesheets, and scripts to users based on their geographic location. This helps reduce latency, resulting in improved user experiences. CDNs are best suited for caching and delivering static content with low latency to users globally.

In the context of a content delivery network, if your primary goal is to optimize the delivery of static content, a Content Delivery Network (CDN) would be a better choice. However, if you require advanced features such as global load balancing, URL-based routing, and web application security, Front Door Azure may be a more suitable option for your needs.
