Amazon CloudFront is a service offered by AWSmanagement console that speeds up the distribution of your static and dynamic web content, such as .html, .css, .php, and image files, to the users. CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you’re serving with CloudFront, the user is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance. If the content is already in the edge location with the lowest latency, CloudFront delivers it immediately. If the content is not in that edge location, CloudFront retrieves it from an Amazon S3 bucket or an HTTP server (for example, a web server) that you have identified as the source for the definitive version of your content.
Go to services click on S3
create a bucket.i have given the name as mytestbucket but it was not created it stated that requested bucket is not available
i have given a new name mytestbucketd1234 then it es created successfully

while creating the bucket i have set permissions and made it public as shown in below
click on the manage public permissions select the options for everyone read , write
final step in creation of bucket is shown below

It has disabled after few minutes and i have selected the radio button present on left corner then select the option on upper corner then i have deleted the bucket also
critical analysis:
Here the image is served from a traditional web server, not from CloudFront.
the image was serving using the URL, the users can easily navigate to this URL and see the image, their request was routed from one network to another through the complex collection of interconnected networks that comprise the Internet until the image was found
The number of networks and the distance that the request and the image must travel have a significant impact on the performance, reliability, and availability of the image.
CloudFront speeds up the distribution of the content by routing each user request to the edge location that can best serve your content. Typically, this is the Cloud Front edge location that provides the lowest latency. This reduces the number of networks that users’ requests must pass through, which improves performance. Users get lower latency the time it takes to load the first byte of the file and higher data transfer rates. You also get increased reliability and availability because copies of your files are now held in multiple edge locations around the world.
