How do CDN Work?

Cyber Security Degrees

What is a CDN?

A content delivery network (CDN) is a group of servers distributed geographically that works together to deliver Internet content quickly. It allows you to quickly transfer assets required for loading Internet content, including HTML pages, javascript files, stylesheets, and videos. With the popularity of CDN services, the majority of web traffic is currently served by CDNs. This includes traffic from major sites such as Netflix, Amazon, and Facebook.

What is a CDN?

The request is answered by servers closest to the visitor. The CDN copies website pages to a network server that is distributed in different geographical locations. This caches the content of the page. A CDN redirects a request to a website that is part of the network to a CDN server that is closest to the user. The CDN then delivers the cached content. CDNs can also communicate with the origin server to deliver the cached content. The whole process of bouncing via CDNs can be done almost invisibly by the user. A user will only know if a CDN was accessed if the delivered URL differs from the one requested.

The Top 4 Benefits of using CDN (Content Delivery Network).

The benefits of using a CDN vary based on the size of the Internet property. Therefore, the most important benefits for most users can easily be broken down into four components.

  • Reduce bandwidth costs
    Website hosting costs are considered to be the primary expense. Bandwidth consumption is a cost that websites must pay for. CDNs can reduce the amount of data that an origin server has to provide by using caching and other optimizations. This helps lower hosting costs for website owners.
  • Redundancy and increased content availability
    Websites can be disrupted by large amounts of traffic and hardware failures. A CDN’s distributed nature allows it to handle more traffic than other origin servers and resist hardware failures better than any of its peers.
  • Improved website loading times
    With the help of a nearby partner, website visitors will experience quicker page loading times.CDN server. A CDN can reduce bounce rates and increase time spent on the site by reducing the likelihood of visitors leaving slow-loading sites. This is because a website that loads faster will attract more people to stay on the site for longer periods of time.
  • Improved website security
    and you can also increase web security through the use of security certificates.DDoS mitigation, and other optimizations.

CDN Service

Let’s take a brief look at CDNs and what they offer. This CDN is part of Comodo’s web security called cWatch: a Managed Security Service for websites and web applications that incorporate a Web Application Firewall (WAF) provisioned over a Secure Content Delivery Network (CDN). The solution is managed by a Cyber Security Operation Center (CSOC), staffed 24x7x365. It’s powered by a Security Information and Event Management system (SIEM) that can leverage data from over 85 million endpoints to identify and mitigate potential threats. The cWatch web security tool provides preventive services, malware scanning, and removal services to help organizations take a proactive approach in protecting their brand and business from attacks and infections. cWatch also offers vulnerability scanning to provide online merchants, businesses, and other service providers handling credit cards online with an automated and simple way to stay compliant with the Payment Card Industry Data Security Standard (PCI DSS).

The Comodo CDN offers the following benefits: [Updated 2021]

  • SecurityComodo’s CDN is the only one that is built on security. It features a secure machine-learning core that aggregates and examines real-time threat information and distributes it to each of its security services.
  • You can get faster speeds website data is copied to 29 locations around the globe to ensure that it travels less distance to customers no matter where they live and provides a quicker experience. A person located in Europe can load data from a CDN Node in Europe even though the website is hosted in the USA.
  • You can save money save bandwidth and reduce usage, you can use compression and browser caching technology.
  • Content protection: Flexible key and proxy authentication will allow you to protect premium/paid content and prevent hot-linking.
  • SEO benefits: Websites that use search engines are rewardedCDNHigher rankings in search results.
  • High availabilityTraffic can be automatically scaled down and up because the CDN is capable of serving content with nearly unlimited capacity. The server will also be able to maintain optimal speed even under challenging conditions, so unpredicted traffic surges will not be a problem.
