Introduction
Microsoft Azure CDN is a content delivery network (CDN) service that helps businesses deliver content to users with high performance and reliability. Azure CDN has a global network of servers that are located in over 100 locations around the world. This allows Azure CDN to deliver content to users with low latency and high throughput. Azure CDN also offers a variety of features that can help businesses improve the performance of their websites and applications.
Frequently Asked Questions (FAQs)
- What is a CDN?
A CDN is a network of servers that are distributed across the globe. When a user requests content from a website, the CDN will deliver the content from the server that is closest to the user. This can significantly reduce the latency and improve the performance of the website.
- How does Azure CDN work?
Azure CDN works by caching content on its servers. When a user requests content from a website, Azure CDN will first check to see if the content is cached on one of its servers. If the content is cached, Azure CDN will deliver the content from the cached server. If the content is not cached, Azure CDN will fetch the content from the origin server and then cache the content on one of its servers.
- What are the benefits of using Azure CDN?
There are many benefits to using Azure CDN, including:
- Improved website performance
- Reduced latency
- Increased throughput
- Improved reliability
- Reduced costs
