The Content Delivery Network, or CDN for short, is a set of Edge Servers, or POPS<\/a>s, designed to increase the loading speed and bandwidth of websites based on strategy. Special events have been held in different parts of the world.<\/span><\/span><\/p>\n

Using a CDN, in addition to the security benefits and savings in host resources, is also effective in SEO. Websites that use CDNs load faster than those that do not. And since even milliseconds are important to Google and ranking results, such sites grow rapidly in multi-step results. And their incoming traffic increases.<\/span><\/span><\/p>\n

What is a Content Delivery Network or CDN?<\/span><\/span><\/h2>\n

As mentioned, a content distribution network, also known as a content delivery network, is a set of edge servers set up according to specific parameters around the globe. The purpose of creating these databases is to deliver digital content to Internet users as soon as possible. So that as soon as the user requests, he is redirected to the nearest CDN server (spatially). And this is due to the slow and delayed loading of Prevents pages.<\/span><\/span><\/p>\n

In other words, the main purpose of the CDN service is to maintain and cache a copy of your site assets such as HTML, JavaScript, CSS, and images. With the first click of the user, these assets from the nearest database Content delivery network servers will be displayed to them. In other words, to use the content of advanced sites equipped with CDN, the user, wherever he is in the world, will not feel any slowdown in the loading of the pages of that site.<\/span><\/span><\/p>\n

CDN architecture<\/span><\/span><\/h3>\n

The Content Delivery Network (CDN) consists of two general elements at its core: the Point of Presence or POP and Edge Servers.<\/span><\/span><\/p>\n

Point of Presence (POP):<\/span><\/span><\/h3>\n

The point of presence, usually abbreviated as POP, is a specific geographical location where a set of edge servers is set up. Also, the sum of all the points in the whole world that form a network is called POPs or points of presence. It is interesting to note that the number and location of POPs that make up a content delivery network have a significant impact on the full and global coverage of that CDN.<\/span><\/span><\/p>\n

Edge Servers:<\/span><\/span><\/h3>\n

Edge servers are located in the middle of the network, meaning that they are installed in points of presence (POPs). These servers are proxy caches that function similarly to web browser caches. Instead of re-creating the assets and content of the website, they keep a copy of its cache to show to the user upon request. Each server embedded in the presence point operates for a specific CDN.<\/span><\/span><\/p>\n

The distribution of presence points is different for each CDN, so that some owners of this service want more space with low-capacity servers, while others prefer high-capacity servers with low numbers. Therefore, to analyze the performance of CDNs, we must know the location or point of presence (POPs) of the server itself and the geographical area of \u200b\u200bits users.<\/span><\/span><\/p>\n

How CDNs work<\/span><\/span><\/h3>\n

As you can see, the content production network is a vast collection of servers scattered around the globe, the goal of which is to direct the user to the nearest base or point of presence. In other words, when a user requests to view content from your site, they will be directed to the closest server base in the blink of an eye. There are many ways to direct a user to a specific point of presence (POP), one of which is the IP Anycast method.<\/span><\/span><\/p>\n

Suppose a website does not have a content distribution system. All the assets of the site, regardless of the user’s location, will be sent to him from a specific location. It does not matter if he is in Australia, South Africa, or anywhere else; all the content of the site is being sent to him from a specific point, which slows down the loading process.<\/span><\/span><\/p>\n

Content types of CDNs<\/span><\/span><\/h3>\n

After examining the general use of the global Internet by the world’s population, it was found that most of the information that users consume through bandwidth is photos, videos, and audio files, respectively, and the good news is that CDNs support a variety of content formats. And you can use them to display any content to the user:<\/span><\/span><\/p>\n
