The purpose of the CDN is to cache and more quickly serve static content based on the geographical location between the origin server and the user making the request. This means when someone in Japan visits your website hosted in the United States, it will load just as fast as a website hosted in Japan. The difference between them can be seen when viewing the source for your page, which are mostly aesthetic. The differences are:. Whether you're using a Zone CDN or a Custom CDN to cache the static elements of your website, a CDN can improve your click through rates since slow loading websites are often abandoned before they load.
What is a CDN? The benefits of using a CDN are: Improved content availability and redundancy - High volume traffic or hardware failures can cause downtime for your website, a CDN distributes the load so your site can handle more traffic and endure hardware failure better than a single origin server. Improved load times - Users are served content from a Point of Presence PoP geographically closer to them than the origin server which means faster load times for your website.
Increased security - A CDN can increase security by mitigating Distributed Denial-of-Service DDoS attacks, preventing vulnerability hacks and stopping brute force attempts against your website login pages and more. Zone URL CDN are less expensive to run maintain so are typically offered as a free or limited use addition to another product.Amazon CloudFront is a fast content delivery network CDN service that securely delivers data, videos, applications, and APIs to customers globally with low latency, high transfer speeds, all within a developer-friendly environment.

Azure CDN Documentation
CDNs store cached content on edge servers in point-of-presence POP locations that are close to end users, to minimize latency. Azure Content Delivery Network CDN offers developers a global solution for rapidly delivering high-bandwidth content to users by caching their content at strategically placed physical nodes across the world. This name can be an endpoint hostname or a custom domain.
An edge server in the POP caches the file and returns the file to the original requestor Alice. This process results in a faster, more responsive user experience. Every CDN endpoint represents a specific configuration of content deliver behavior and access. To organize your CDN endpoints by internet domain, web application, or some other criteria, you can use multiple profiles.

The benefits of using Azure CDN to deliver web site assets include: Better performance and improved user experience for end users, especially when using applications in which multiple round-trips are required to load content.
Large scaling to better handle instantaneous high loads, such as the start of a product launch event. Distribution of user requests and serving of content directly from edge servers so that less traffic is sent to the origin server. The origin server returns the file to an edge server in the POP.
Limitations Each Azure subscription has default limits for the following resources: The number of CDN profiles that can be created. The number of endpoints that can be created in a CDN profile. The number of custom domains that can be mapped to an endpoint.Take5: Enabling CDN on Google Cloud Platform

The premium version of SmartFTP is another great option for professional users thanks to its extensive protocol support.As with most pieces of technology, CDNs are not magic and actually work in a pretty simple and straightforward manner.
When a web browser makes a request for a resource, the first step is to make a DNS request. Making a DNS request is a lot like looking up a phone number in a phone book: the browser gives the domain name and expects to receive an IP address back.
For your simple blog or small commercial web site, a domain name may have a single IP address; for large web applications, a single domain name may have multiple IP addresses. Physics determines how fast one computer can contact another over physical connections, and so attempting to access a server in China from a computer in the United States will take longer than trying to access a U.
To improve user experience and lower transmission costs, large companies set up servers with copies of data in strategic geographic locations around the world. The server handling DNS requests for the domain name looks at the incoming request to determine the best set of servers to handle it. Keep in mind that companies may optimize their CDNs in other ways as well, for instance, redirecting to a server that is cheaper to run or one that is sitting idle while another is almost at capacity.
Edge servers are proxy caches that work in a manner similar to the browser caches. When a request comes into an edge server, it first checks the cache to see if the content is present. The cache key is the entire URL including query string just like in a browser. If, on the other hand, the content is not in the cache or the cache entry has expired, then the edge server makes a request to the origin server to retrieve the information.
The origin server is the source of truth for content and is capable of serving all of the content that is available on the CDN. When the edge server receives the response from the origin server, it stores the content in cache based on the HTTP headers of the response.
For example, Yahoo! The combo handler takes a request whose query string contains filenames and concatenates the files into a single response. The domain yui. CDN and will redirect you to the closest edge server based on your location.
This particular request combines two files, yui-base-min. So if an edge server receives this request and has no content, a request is made to the origin server to retrieve the content. The edge server can then serve up the appropriate content. I frequently get confused looks when I describe systems similar to the combo handler.
There is a misconception that CDNs act like FTP repositories, where you simply upload static files so that others can retrieve them. An edge server is a proxy, the origin server is the one that tells the edge server exactly what content should be returned for a particular request.
The origin server may be running Java, Ruby, Node. The edge server does nothing but make requests and serve content. So the YUI combo handler exists only on the origin server and not on the edge servers. The CDN is a cache, meaning that is has value when it can serve data directly and not need to contact the origin server. If an edge server needs to make a request to the origin server for every request, then it has no value and in fact, costs more than just making the request to the origin server itself.
That means not only will the same user receive content from cache, but all users will receive the same data from cache. Once the cache is primed with content, all users benefit. This is for two reasons: first, so the browser will cache the resources for a long time, and second, so the CDN will cache the resources for a long time. There are several ways to work around this.

The main issue here is not, if any individual request is faster or not, but using a CDN some browser may be able to use cached versions of the libraries requested and do an HTTP request to get them at all.
