How does a CDN work?
A content delivery network gives out more than 50% of the internet’s traffic. It reduces latency by reducing the physical distance of the request sent to the web page.
An excellent example to make things more transparent would be a visitor sitting in the US, trying to open a UK origin webpage.
Now, suppose the request needs to travel across the Atlantic; it will take a considerable amount of time to load the page.
However, with CDN, there is a cached version of the web content in various geographical locations.
These locations are known as the points of presence and contain their own caching servers to deliver that particular content in the user’s area.
This means, through CDN, the person sitting in the US trying to open a UK-based website will now be able to load the web page within seconds.
CDNs can deliver a wide variety of content. These contents include 4K and HD quality video, audio streams, software downloads, data records, and so much more.
Having a CDN is essential for fast, secure, efficient, and effective content worldwide.
Most businesses have now come online, especially after the pandemic. Every business has an online presence and is focusing on making it better. The interne3t enables people to connect, shop, sell, share, and a lot more.
With an increased number of visitors on the website, it becomes tough for content/product providers to maintain different content delivery, adjust it according to devices, and secure the data and user’s online presence.
You’ll save web hosting bandwidth and rescue the overall visitor hit. If you’re regularly hitting the limit of your hosting plan, and paying overage charges, try using one of the Proxy/WAF CDNs below.
You’ll end up eliminating the extra bot and spam traffic reducing your hosting overage charges. It will secure your website and reduce the threats of DDoS attacks and fresh SSL certificates.
A good CDN help businesses overcome these challenges of media delivery.
Traditional CDN V/S Proxy/WAF CDN
Content delivery networks can be categorized into two parts.
- Traditional CDN: These CDNs cache a copy of all of your content and media first. They then utilize a subdomain or a random URL to serve the assets from this random website. When someone visits your site, the request is first made from the client to the hosting provider, and then to the CDN in order to fetch all the assets.
- Proxy/WAF CDN: This is slightly different than the traditional CDN. It still acts like a CDN, however, it intercepts all incoming requests as an intermediary server between the client and the website host. Unlike a traditional CDN, it does not require the use of a subdomain or a random URL.
