Best Content Delivery Network (CDN) Software
What is a CDN?
Content Delivery Network (CDN) providers offer access to a network of servers as well as services that help improve website performance by facilitating the efficient delivery of content to websites. CDN services rely on geographically dispersed points of presence, known as PoPs, that help route the delivery of digital content from the origin server to one that is as close to the browsing user as possible. Organizations use CDN services, such as web caching, request routing, and server-load balancing, to reduce load times and improve website performance. CDN services are often used by organizations that depend heavily on reliable content delivery. Some examples of these include online video streaming providers and e-commerce companies, as both of these are significantly affected by poor web performance. CDN services are often used in conjunction with website hosting services to optimize content delivery speeds, though some CDN services may also offer hosting separately from their CDN services. Some content management systems offer pre-built integrations with CDN services to help users improve their website performance.
To qualify as a CDN provider, a service provider must:
- Allow access to a geographically dispersed network of PoPs in multiple data centers
- Help websites access this network to deliver content to website visitors
- Offer services designed to improve website performance
- Provide scalable Internet bandwidth allowances according to customer needs
- Maintain data center(s) of servers to reduce the possibility of overloading individual instances
