How does a CDN work with an origin server?
As many of the changes to the content on your origin server are propagated to your CDN’s cache servers, the two communicate on a regular basis. The most effective method for updating edge servers is to have your CDN automatically pull the new content from your origin.
Where are the CDN servers located on the network?
Each CDN server is located on what is called the “network edge”—closer to users than the host server, which is where the website originates. For this reason, CDN servers are often called “edge servers.”
How are CDNs used to deliver static content?
CDNs store cached content on edge servers that are close to end users to minimize latency. CDNs are typically used to deliver static content such as images, style sheets, documents, client-side scripts, and HTML pages.
Why is it important to use a CDN?
If someone from the United States (US) accesses your site, the CDN serves that user from an edge server in the US, closer to the user, instead of from your UK-based origin server for the web page. The result is faster content loading and web application performance, as well as improved user experience.
How does edge connect to the origin server?
CDN edge servers interact with an origin server when the latter delivers content to the former. The two could communicate with each other using a push or a pull method. In the push method, you will update the CDN with changes made to the origin servers.
What does multi origin mean for Azure CDN?
Multi-origin support eliminates downtime and establishes global redundancy. By choosing multiple origins within an Azure CDN endpoint, the redundancy provided spreads the risk by probing the health of each origin and failing over if necessary. Setup one or more origin groups and choose a default origin group.
When to avoid generic subdomains in origin server?
Avoiding generic subdomain names – If some of your domain-related services (e.g., FTP or mail) are not protected by a CDN, their subdomain can be resolved to uncover the IP address of your origin. This is why, after onboarding a CDN, you should avoid using generic subdomains for these services.
