Today it’s not about how good your content but it’s a step further. The overall experience of viewing your content decides your audience’s feedback. A lot of things have been developed over years in order to facilitate this experience. CDN could be considered ace from that pack.
Content Delivery Network, popularly known as CDN refers to a highly distributed platform of servers that helps in minimizing delay in loading web page content. They are a geographically distributed group of servers that work together with the aim of providing fast delivery of content. It reduces the physical distance between the server and the user.
CDN was created nearly 20 years ago in order to channelize the massive amount of data directly to users and has developed drastically over the years. There are dedicated researchers and developers working to enhance the overall user experience and improve the services provided. While a first-generation content delivery network was built in the 90s, it was focused majorly on dynamic and static content delivery. Second generation CDN was a bit more advanced and was developed while keeping streaming video, audio, and video on demand in mind. This generation also saw the use of P2P and cloud computing techniques, as well as the clearing of a path for delivering website content to mobile users.
We are currently witnessing third-generation CDN which is already being incorporated at an extremely rapid speed. These are extremely modeled for the community. Today content delivery networks are a step ahead from just delivering content, they provide a wide variety of options to streamers to make their content user-friendly. Self-configuring, as well as self-managing and autonomic content delivery, are developing to be the new technological mechanisms.
How does Content Delivery Network work?
More than half of today’s internet traffic is served through CDN. The major aim of CDN is to reduce latency- time taken between submitting a request for a web page and then loading it completely on your device. It does that by reducing the physical distance that request has to travel. For example, assume someone living in India, requesting content that originates at America based server. Due to massive physical distance, users would witness long loading periods. This is where CDN comes in they store cached versions of your website content in multiple geographical locations. Which are known as “points of presence” (PoPs). These PoPs have their own caching servers and are responsible for delivering content to end-user.
Why should we use CDN?
CDNs provide an easy way to boost a website’s speed while also lowering latency. As a result, they are critical for delivering content to users all over the world in a timely, efficient, and secure manner. This content is not limited to website content; it can also include 4K and HD-quality video, audio streams, apps, games, and operating system updates. With website visitor attention spans shrinking by the day, it is critical to delivering content as soon as possible.
With the internet reaching remote areas and businesses going online, the world is using the Internet to shop, connect, and share. Content providers face an increasing number of challenges, including delivering different types of content, adjusting the content for different device types (device detection), and securing data and their end users’ online presence. Because of the inherent capabilities of a content delivery network, CDN providers are uniquely positioned to assist businesses in overcoming these diverse media delivery challenges.
When it comes to images, CDN is more useful than you think. It’s not just caching and storing content but CDNs can help you automatically optimize your images. There are certain image CDN that can automatically select the most suitable format for images. CDN can convert images to WebP and compress them to 40% without affecting quality. They can compress every image depending upon what they are meant for and help you achieve perfect balance and size.
Many people prefer Content Delivery networks because as it optimizes their pages as per user experience. CDN sends responsive images to all devices dynamically making changes to format, quality, pixels, density etc. CDNs can also improve on google search rankings as google appreciates faster websites and rank them higher. Another benefit out of a faster website is the increased conversion rates as fewer people tend to bounce out when the website is fast.
Streaming is another domain where Content Delivery networks can do wonders. Live streaming requires a strong bandwidth as generally live streaming videos are large in size. Along with that, the camera quality is bound to deteriorate. As per reports by the State of Streaming, nearly 63% of live-stream viewers have cited buffering issues. This is where CDN comes in, they send video to servers rather than directly to viewers, and servers distribute videos accordingly. CDNs also compress videos and thus it’s easier for viewers to stream.
