There is no explicit Clone button  Basically what you do is create an image  or snapshot of an existing EC2 instance  and then spin up a new instance using that snapshot   First create an image from an existing EC2 instance       Check your snapshots list to see if the process is completed  This usually takes around 20 minutes depending on how large your instance drive is       Then  you need to create a new instance and use that image as the AMI

Nowadays it is even easier to clone the machine with EBS-backed instances released a while ago  This is how we do it in BitNami Cloud Hosting  Basically you just take a snapshot of the instance which can be used later to launch a new server  You can do it either using AWS console  saving the EBS-backed instance as AWS AMI  or using the EC2 API tools    create a snapshot with ec2-create-snapshot and then launch an instance from a snapshot   Cloning the instance is nothing else but creating the backup and then launching a new server based on that  You can find bunch of articles out there describing this problem  try to find the info about  how to      backup or resize the whole EC2 instance  for example this blog is a really good place to start  alestic com
