This is going to be an amazing post, I can feel it!
I would like to share my knowledge and opinion about one of the best things ever happened to web technologies. Note that, I’m going try to explain what Akamai is at the simplest way.
Why is it one of the best things, you might ask. I’m going to explain what its features one by one.
Content Delivery Network
First of all, Akamai is a CDN. So, what is a CDN?
Basically, A CDN is a geographically distributed network of proxy servers and data centres which aims to distribute services with high availability and high performance. CDNs are commonly used today and serve a large portion of the Internet content, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social networks.
There are free CDNs such as Cloudflare, Incapsula(They are free for personal usage) and there are paid CDNs such as Akamai, Amazon CloudFront, Azure CDN. Each of these provide various features. You can take a look about their features here(cdnoverview.com). It is up to businesses which to use based on their requirements.
