I am really not going to fool you and say you can get CDN hosting in very low rates, it’s just not built for it. I believe we should rather be thankful that we can use such stuff with excellent features at the rates you might find currently. Just look back 3-4 years and even with high price you’d be struggling to get things you get currently at 50-60% lesser price.
However, I have used Akamai myself, so I will be fair in saying they do charges bit too much. I have personally shifted myself to
BitsNGo CDN, as they have pretty simple and straight forward setup, but by no means is ordinary instead it’s well-advanced and with Premium global infrastructure, guaranteed speed and best part is 100+ POPs across the globe at very affordable rates (not cheap but affordable). You can try out their free 30 days trial with no pre-commitments, so good luck.
