Optimizing website with VNCDN: Accelerating the page load speed and enhancing user experience

According to a study by Forrester, utilizing CDN can help reduce bounce rates by up to 20%. Additionally, Gartner affirms that employing CDN can cut storage and bandwidth costs by up to 50%. This underscores the significance of implementing CDN into a business's system in today's era. Hence, let's explore the capabilities of CDN in optimizing the enterprise website together with VNETWORK.

What is CDN?

CDN (Content Delivery Network) is a content distribution network consisting of a distributed system of servers located at various locations worldwide. It is used to store and distribute static content, such as images, videos, documents, etc., to users.

When users access a website, the CDN determines their geographical location through their IP address and then selects the nearest server within the global network. This process optimizes the website speed by distributing content from the nearest server, reducing loading times, and enhancing the website's ability to handle traffic. Additionally, CDN stores copies of the content on different servers to alleviate the load on the origin server and ensure quick readiness when needed.

Benefits of Optimizing a Website with CDN:

Shortened Load Time and Improved User Experience:

Improving Load Speed: Long loading times or delays in accessing content can lead to user impatience and decreased interest, prompting them to prioritize other brands. Using a CDN with servers distributed globally accelerates the website by delivering content from servers closest to users. This enhances the user experience, reduces loading times, and helps maintain interest, preventing users from turning to other brands due to impatience.

Reducing Lag: Lag, or the delay between executing an action and seeing it on the interface, can create difficulties for users, such as scrolling or clicking links. CDN speeds up web loading by storing content copies on servers worldwide. When users access the website, content is retrieved from the nearest server, effectively reducing response times.

Ensuring Stable Image and Audio Quality: As graphic and audio effects become more sophisticated, low-quality transmission can hinder user experience. CDN plays a crucial role in improving image and audio quality across various devices. By converting formats and sizes while maintaining quality, CDN ensures content is displayed appropriately for each device and network condition. The extensive distribution system of CDN also supports the delivery of high-quality and diverse media files, enabling users to access content without quality degradation or interruptions during webpage loading.

Improving Website Ranking on Search Engines and Enhancing Conversion Rates

CDN plays a crucial role in optimizing SEO scores and enhancing website performance. When integrated with CDN, the website stores copies in the cache memory from the nearest server when users access it. This helps improve page loading speed, overall performance, and the reliability of the website. The website operates more efficiently, attracting and retaining users, while simultaneously boosting SEO scores.

Moreover, CDN also helps increase PageSpeed Insights scores by optimizing the transmission of resources such as images, CSS, and JavaScript from servers close to users. This reduces page loading time, enhances user experience, and, in turn, elevates the performance rating of the website.

How CDN Optimizes Websites?

Distributing Website Content to Users from the Nearestxa Servers

Helps reduce the distance between users and the website server, thereby decreasing data transfer time. For example, if a user in Vietnam accesses a website with its origin server in the United States, using CDN will distribute the website content from a CDN server in Vietnam. This minimizes the distance between users and the CDN server, reducing data transfer time.

Reducing File Size

By employing techniques such as compression, file minification, and low-sized image formats (WebP), CDN effectively reduces file sizes while maintaining quality. This aids in decreasing the amount of data that needs to be transmitted, ultimately speeding up page loading.

Utilizing Connection Reuse

CDN optimizes the reuse of connections between users and CDN servers by storing local versions of frequently requested files. This helps reduce the number of connections required to load the website, thereby accelerating page loading speed and limiting server overload.

Improving Security Measures

TLS/SSL Certificates: Help encrypt data transmission between users and the website, preventing attacks such as eavesdropping and impersonation. DDoS Attack Prevention: Utilizes techniques like distributed access traffic and access filtering to protect the website from DDoS attacks. Access Control: Manages access to website content using technologies such as authentication and authorization.
