Azure Front Door and Edge Locations explained

Azure Front Door is a global, scalable, and secure content delivery network (CDN) service offered by Microsoft Azure. It provides a range of features, including global HTTP(S) load balancing, custom domain support, and content caching, to help you deliver high-quality, responsive web experiences to your users.

One of the key features of Azure Front Door is the use of edge locations, which are points of presence (PoPs) located around the world that are used to deliver content to users. When a user requests content from a website or application that is powered by Azure Front Door, the service routes the request to the nearest edge location. The edge location then retrieves the content from the origin server and delivers it to the user.

This helps to reduce latency and improve the performance of your web experiences, as the content is delivered to the user from a location that is physically closer to them. Azure Front Door has over 60 edge locations worldwide, ensuring that users can access your content quickly and reliably, regardless of their location.

In addition to delivering content from edge locations, Azure Front Door also provides a range of security features to help protect your web applications and APIs from threats such as DDoS attacks and web application vulnerabilities. These features include built-in WAF capabilities, as well as the ability to enable custom rules to meet your specific security needs.

Overall, Azure Front Door is a powerful and flexible CDN service that enables you to deliver high-quality, responsive web experiences to your users, while also providing a range of security features to help protect your applications and APIs.

Azure CDN’s vs Front Door

Azure Content Delivery Network (CDN) and Azure Front Door are both content delivery network (CDN) services offered by Microsoft Azure. They both provide a range of features to help you deliver high-quality, responsive web experiences to your users, but they differ in their specific capabilities and use cases.

Azure CDN is a global CDN service that enables you to deliver content, such as HTML, CSS, JavaScript, and media files, to users quickly and reliably. It uses a network of edge servers located around the world to cache content close to users, reducing latency and improving the performance of your web experiences. Azure CDN also provides a range of features to help you optimize your content, including automatic compression and content expiration controls.

Azure Front Door is a more comprehensive CDN service that provides global HTTP(S) load balancing, custom domain support, and content caching, in addition to the features offered by Azure CDN. It is designed for use cases where you need to deliver content from multiple origins, such as web applications or APIs, and want to manage the routing and traffic management at the network layer. Azure Front Door also provides built-in WAF capabilities and the ability to enable custom rules to meet your specific security needs.

In summary, Azure CDN is a simple, cost-effective solution for delivering static content to users, while Azure Front Door is a more comprehensive solution that is well-suited to use cases where you need to deliver dynamic content from multiple origins and want to manage the routing and traffic management at the network layer.
