What is CDN (content delivery network)?<\/h2>\n\n\n\n

A CDN or content delivery network, a content distribution network, is a set of servers that work together to allow visitors quick access to web content.<\/p>\n\n\n\n

CDN has servers in multiple locations around the world. When visitors want to access content on the page they use, the network delivers content to them from the server closest to them. This helps the content delivery network to reduce page loading time.<\/p>\n\n\n\n

How does CDN work?<\/h2>\n\n\n\n

Suppose you want to access a page. Normally, your browser should connect directly to our server. However, it may take some time, depending on how far away you are from it.<\/p>\n\n\n\n

If our server is located in Dubrovnik, a person from Vara\u017edin would connect faster than someone from America or India.<\/p>\n\n\n\n

This is where the Content Delivery Network (CDN) enters the scene. If we use it, it will store (cache) copies of our site on its servers in various locations around the world. When you then try to access our site, it will deliver the cache pages from the server closest to you.<\/p>\n\n\n\n

For example, if the content delivery network has servers in Frankfurt and the United States, it would deliver content to US visitors from its server in the United States and to visitors from Spain and India from its servers in Frankfurt.<\/p>\n\n\n

Importance of the network for content delivery<\/h2>\n\n\n\n

Content delivery networks (CDNs) reduce latency and speed up page loading times, ensuring that visitors can access websites faster than usual.<\/p>\n\n\n\n

Latency is the time it takes for data to be transferred between two networks. When you try to access our site, latency is the total time it takes for your browser to communicate with our server and for our server to return the requested information to your browser.<\/p>\n\n\n\n

The further our server is away from you, the higher the latency and the longer you will wait to receive our content.<\/p>\n\n\n\n

Page loading time is a combination of latency and all the other time it takes for content to appear in your browser. High latency leads to a long page loading time. This negatively affects the user experience as visitors wait longer to access your content.<\/p>\n\n\n\n

However, the content delivery network significantly reduces this by delivering the website from the server closest to the visitor. This server, called an edge server, reduces latency, page loading time and page drop-out rate, and improves user experience, engagement, and conversion rates.<\/p>\n\n\n\n

Content delivery networks also help improve security and reduce unavailability times. Because your content is spread over multiple servers, visitors can still access your page even when your original server is unavailable.<\/p>\n\n\n\n

Content delivery networks typically also offer advanced security features, such as SSL\/TLS encryption and distributed denial-of-service (DDoS) protection. They help protect your site and visitors and reduce the impact of malicious attacks directed at the site.<\/p>\n\n\n\n

Content delivery network restrictions<\/h2>\n\n\n\n

Although content delivery networks offer a number of advantages to the pages that use them, they can also significantly affect page usability, user experience and revenue.<\/p>\n\n\n\n

1 Inconsistent content<\/h3>\n\n\n\n

Content delivery networks store content in cache on edge servers. While this allows content to be delivered quickly to visitors, it can lead to problems if the cache on edge servers is not deleted or updated regularly.<\/p>\n\n\n\n

This may cause visitors to see different content depending on which edge server delivered the content to them. Sometimes edge servers may not be up to date at all, so they return content that differs from the original server.<\/p>\n\n\n\n

2 Dynamic Content Latency<\/h3>\n\n\n\n

While content delivery networks are highly efficient in delivering static content quickly, they can introduce latency when it comes to dynamic content, as dynamic requirements often have to be directed back to the source server.<\/p>\n\n\n\n

This may slow down the response time, especially if the server is away from the visitor. It can also result in a less responsive experience for users who work with real-time data or perform transactions.<\/p>\n\n\n\n

3 Problems with troubleshooting<\/h3>\n\n\n\n

Content delivery networks can complicate the troubleshooting process when problems arise. This is because it can be difficult to identify the source of the problem, in particular because content delivery networks deliver content from multiple edge servers rather than from a single source server.<\/p>\n\n\n\n

This complexity may lead to a longer problem-solving time, as technical teams may need to explore multiple servers instead of one. The technical team can also spend considerable time and resources in communicating with the content delivery network provider.<\/p>\n\n\n\n

4 Misconfigured settings<\/h3>\n\n\n\n

Content delivery networks can be complex to configure and manage. This can lead to errors, including misconfigured settings that can affect the security and performance of the site.<\/p>\n\n\n\n

For example, incorrect cache rules can cause the network to deliver obsolete content. Incorrect SSL settings can expose the site to security risks. All this can have a significant impact on the usability of the site and user experience.<\/p>\n\n\n\n

5 Less control over availability<\/h3>\n\n\n\n

Pages that use networks to deliver content are subject to security and performance problems that affect the network itself. This means that the site can be unavailable even when there are no problems on its side.<\/p>\n\n\n\n

For example, a page may be unavailable when a content delivery network is attacked or experiences a downtime or technical issue. This can be challenging for bloggers because solving such problems is beyond their control and depends on the content delivery network.<\/p>","protected":false},"excerpt":{"rendered":"
