What is a CDN provider?

A content delivery network is a series of geographically distributed servers that work together to provide faster delivery of content such as images, videos and core website files, i.e. CSS files.

CDN's usually crawl your website and cache a record of something that changes infrequently such as content files. They'll store a copy on various servers around the world. 

When a visitor to your website loads a page, rather than downloading the image from your web host, which might be in the USA, the image will be served up from a server closest to them, maybe in Sydney or Melbourne. 

If there is no cache then the image is downloaded from the source, i.e. the US hosting server. Once a visitor loads an image not currently cached it's often then added to the cache. 

If the content changes, you'll need to flush the cache with your CDN provider, much like you'd flush your DNS on your computer if you were experiencing issues loading a website. 

Different CDN providers offer different server locations, with some focusing more in certain areas than others. Keycdn for example has an Auckland server which is good for websites with lots of New Zealand visitors, whereas other CDN's only have Sydney or Melbourne servers. 

What's the cheapest CDN provider? 

When it comes to CDN I'd say the cheaper way is to pay per GB or TB of data. There's no point paying $10 or $20 per month for Terabytes of data when you may only use a few GB.

Small websites such as ours, only use about 50GB of data per month, so we only much less than this for our CDN, so at the Bunny CDN rates of $0.03 per GB our monthly bill would be $1.50. 

This is a much cheaper way of buying a CDN. You will need to topup a minimum of $10-$20 but this should last you a good few months (or years) for smaller websites. 

Larger websites should consider their estimated costs as a monthly plan could work out cheaper.
