Is the CDN and Cloud computing are same? If both are different, how they differ? I have googled it, when someone asked me this question. But i could not able to get any clear idea on this. So can anyone explain about this, which would be greatly useful to lot of people.
And also please explain where the CDN will be used and where the cloud will be used?

Cloud computing and CDNs are similar because they each serve content from geographically distributed servers. But this is where they vary: A CDN delivers content as quickly as possible, while cloud computing is based on flexibility, scalability and on-demand delivery of applications and data.
Since Cloud CDN uses Cloud Load Balancing to provide routing, health checking, and anycast IP support, it can be enabled by easily selecting a checkbox while setting up your backends or origins. Cloud CDN makes it easy to serve web and media content using Google Cloud Storage.
A content delivery network (CDN) is a group of geographically distributed servers that speed up the delivery of web content by bringing it closer to where users are.
To answer the question: Yes. You need a CDN even if you are already hosting your digital assets on the cloud. Cloud hosting has a huge number of advantages but it has a different set of capabilities compared to a CDN. A CDN brings immense value to your website in terms of speed, efficiency and enhanced security.
CDN is simply a network of servers that replicate your binary files so that they are served from geographically close locations. CDN has been around for a lot longer than cloud computing as you know it today.
Not every cloud provider is a CDN, and not every CDN is a cloud computing provider.
Cloud computing is simply - dividing up a large computing resource (usually processing power) into little chunks which you can use remotely.
CDN is simply - a bunch of "disks" that are spread across the world in different datacenters. You upload your file to one of these disks - and then tell it where your customers are coming from. It will then copy the same file to other disks that are nearer to your customers; giving your visitors a faster experience. This collection of disks is called the content delivery network.
One of the biggest names in CDN is Akamai.
