Amazon CloudFront is best suited when there is a need of speed in serving static and dynanic web contents of a web application. If the content is already in that edge location, CloudFront delivers it immediately. If the content is not currently in that edge location, CloudFront retrieves it from an Amazon S3 bucket or an HTTP server. Amazon CloudFront is not appropriate in case users can tolerate some delays or servers are present near to the location of user. It also Integrates through the W3 Total Cache plugin. Amazon CloudFront Pricing based on bandwidth usage that's the best part of it.
Google Cloud CDN is available globally and supports various load balancers available in different regions around the globe, so I find Google Cloud CDN as one of the best choices for CDN as it serves globally and it is really fast, safe, and secure. It might be not suitable for you if you do not have any technical background.
Lots of configuration options, which allow for different setups and pricing strategies
Lambda@Edge integration allows for really quite complex behaviours to be executed in the cloud at the edge node itself. This means there are a huge amount of possibilities for shaping and altering traffic close to the viewer.
Simple integration to other AWS services (e.g. S3)
There is not really an interface for managing rules directly, compared to market leaders, Google's implementation is probably strong on the technical side but for the average user it might be lacking. There are no advanced features which can be compared to what other leaders in the CDN sector are providing or they can be achieved but with high implementation cost and usage of other products in the Google Cloud suite
CloudFront is a good CDN solution. It can be a bit complicated to implement depending on your needs, but AWS tech support is great. You get to avoid a ton of upfront costs by going with CloudFront. It works best in conjunction with other AWS services in your infrastructure. Once you set it up, you won't need to do much to maintain it. It just works.
I didn't have the need to use support from Google when I was either testing or setting up my website. Information was easily found by searching online if I needed to, and the options that I needed to install or enable were there on the setup page. Honestly, I was a former systems administrator so most of this stuff is not challenging for me.
Have used the IBM Cloud Content Delivery Network for a very short time span like a couple of weeks. Both the setup as well as interactions with other services are a little complicated or not straightforward when compared to AWS. Also, IBM cloud has less number of edge locations than AWS Cloudfront.
We have limited software developers and don't have the need for a big cloud service provider along with their costs. Google Cloud CDN brings to usr, reliability and brand familiarity. Google Cloud CDN also doesn't bother us with pitches or 1000 emails about the products. We went and signed up for it, without dealing with a pushy salesperson.
