Content delivery networks (CDN) provide users with an infrastructure of servers across various data center locations. These networks can effectively and efficiently deliver online resources such as downloadable content, media streaming, or web-based applications, while also ensuring accessibility through high server uptime and overall speed improvements. Businesses commonly utilize CDNs to manage their content distribution and scaling for projects such as lead generation campaigns. Another important use is to enhance network security and website performance globally by sending online traffic through localized servers, which also helps to mitigate threats like DDoS attacks.

Content delivery network (CDN) software is a content distribution tool that utilizes a globally distributed system consisting of proxy servers and their data centers to bring web content to end users.
Content delivery network software providers give their clients complete access to a vast network of servers and a wide variety of services all designed to ensure performance reliability of websites. By facilitating the efficient distribution of digital content to client websites, such content delivery services are becoming a popular solution for a lot of businesses looking to improve the overall performance of their websites.
A typical CDN service relies mainly on geographically positioned points of presence, otherwise referred to as PoPs, that facilitate the route to which the distribution network of digital content most often adheres to, from the server of origin all the way to the proxy server closest to the end user, i.e. the individual who did the browsing and requested the content.
Businesses and organizations rely on content delivery network (CDN) services—like request routing, web caching and server-load balancing—to minimize load times, ensure high performance for their business website and to enhance the overall user experience. CDN software and services are often leveraged by companies that depend heavily on serving content to their customers with a reliable distribution or delivery method.
A couple of examples of these types of companies include providers of streaming media and e-commerce firms. Poor web performance and content distribution can negatively impact these types of businesses in the most significant manner. Content delivery network (CDN) software is often implemented in tandem with other solutions, such as content management systems and website-hosting services. The latter can help improve performance reliability by optimizing content distribution speeds, although some CDN service may also offer web hosting as a separate module.
Additionally, there are content management solutions in the market that offer integration support for content delivery network software to help customer businesses obtain high performance for their websites, including whatever web application they’re using.
CDN service providers deliver multimedia content to end users with consistency, high availability rate and high performance through a globally distributed network of proxy servers located in a number of data centers around the world.
Content delivery network (CDN) solutions distribute several web objects, such as graphics, scripts and texts. The content distribution service also supports delivery of downloadable objects like software, documents, media files and applications, including live and on-demand streaming media, e-commerce, web portals and social networks.
Content delivery network (CDN) software can be categorized based on their core functions and capabilities. In this categorization, there are two basic types you can consider if you’re in the market for content delivery services: traditional or commercial CDN service and enterprise content delivery network or eCDN software.
A traditional CDN service is essentially what has already been previously described in this guide. A content delivery or distribution network is a comprehensive infrastructure consisting of a globally distributed system of servers across multiple data centers. CDN software can serve as a protective shield for the origin server, the server where the content originated. It can protect the origin server from potential threats like DDoS (distributed denial of service) attacks and/or overloads.
Content delivery network software works by caching static or semi-static content as close as possible to the end user. The CDN service is also capable of keeping established SSL or TCP sessions open between the origin server and the end user. A few examples of commercial content delivery services include CDN77.com, KeyCDN, Microsoft Azure CDN, Gumlet, Imperva Cloud Application Security, CacheFly and Google Cloud CDN.
Enterprise CDN software provides access to a robust network of proxy servers with the ability to enhance performance reliability for various types of websites, content delivery services and web application availability on an enterprise scale. Just like a traditional CDN service, eCDN providers make use of geographically dispersed points of presence or PoPs to help route the distribution of content from the origin server to a proxy server that is closest to the end user.
Dynamic web content refers to the kind of content that is often generated on-the-fly by web servers utilizing any of the different web programming languages available, such as Java, Ruby, and PHP. Finally, streaming content is typically comprised of audio and video files that are played either live or on-demand through a web browser control. Enterprise CDN providers are capable of serving content of any type without diminishing performance reliability and user experience.
Enterprise content distribution networks usually rely on a software-defined approach that enables efficient delivery of much larger files, such as high-definition, high-bandwidth media, i.e. HD streaming videos as well as software and web application delivery. While a commercial CDN service does provide some level of scalability, eCDN services are highly scalable and efficient at facilitating the high-bandwidth requirements of larger organizations and enterprises.
Finding the right content delivery network (CDN) provider that meets your content distribution requirements is crucial. When evaluating the different CDN service providers, you have to carefully assess your organization’s bandwidth needs, budget, streaming media capabilities, the technical support offered by the service provider and your audience, specifically the location where most of your website visitors are based. The following are a few key factors to consider when choosing CDN software:
A thorough and successful testing of a potential CDN service provider is typically conducted in a couple of stages: the trial period and the data collection and analysis. The trial period is where you and your team will test the distribution network and its full capabilities, specifically their performance in the regions that are vital to your operation. You should find a way to gather information about performance reliability that is independent of the provider you are trying out. This way, you can compare your findings with theirs when the time comes.
The data collection and analysis phase is where you and your team will compare performance data and other critical information about the CDN service provider. Make sure to include a few key points in your comparisons, such as the availability of customer support, as well as basic and individual functionalities.
Having a better understanding of how content delivery services perform is among the most significant information you can have when in the process of evaluating CDN prospects. One of the key information you should try to obtain is the speed at which your prospective CDN service providers are able to deliver when it comes to different types of content, i.e. static web content, dynamic content and streaming media content.
Additionally, you should also make sure to calculate the nominal, maximal and average latency and throughput values both in light and heavy website traffic.
For any content delivery network (CDN) software to be fully functional, it has to be designed and developed based on a few key principles: availability of service, performance reliability, efficiency, security, flexibility and demand/popularity responsiveness.
The CDN service provider you pick should also offer both individual and basic functionalities. Individual functionalities can address the unique requirements of different customer businesses. But there has to be the basic functions that serve each and every customer. Such basic functions should include real-time CDN usage statistics, FTP file transfer capability and on-demand reset of delivery node cache, a.k.a. purge cache function.
There are several benefits to using the right CDN service provider. However, the significance of those benefits may vary depending on the size of the operation and the content distribution requirements of the organization. The following are some of the key benefits for the majority of users, regardless of their size or needs:
By distributing content to various points of presence that are closer to the location of website visitors, faster page loading times can be improved and user experiences improves along with them. With improved user experience comes better user satisfaction and retention. Web pages that have slow loading times can severely diminish user experience and the time visitors spend on your website, as they will be forced click away from your pages and go to your competitors instead.
One of the primary expenses for websites and web hosting is bandwidth consumption. The more bandwidth your website consumes, the more it will cost your business. By data caching and through other optimization initiatives, content delivery network software will be able to minimize the amount of data an origin server has to provide. This in turn will help reduce the web hosting costs for website owners.
