Cloning an EC2 Instance in AWS

To clone an EC2 instance in AWS, follow these steps:

Step 1: Create an AMI (Amazon Machine Image) from the Source Instance

  1. In the EC2 console, select the instance you want to clone.
  2. Right-click and choose "Image and templates" > "Create image".
  3. Provide a name and description for the AMI.
  4. Optionally, configure additional settings (e.g., no reboot option to avoid downtime).
  5. Click "Create image".
  • ⏳ Note: The AMI creation may take several minutes, depending on the size of the instance’s disk.

Step 2: Launch a New Instance Using the AMI

  1. Navigate to the AMIs section in the EC2 console.
  2. Select your newly created AMI.
  3. Click "Launch instance from AMI".

Step 3: Configure the New Instance

  1. Choose the instance type (e.g., t2.micro, m5.large).
  2. Configure instance details (e.g., VPC, subnet, auto-assign public IP).
  3. Add storage if needed, and configure volume settings (e.g., size, type).
  4. Set up security groups for inbound and outbound traffic rules.

Step 4: Review and Launch

  1. Review the instance configuration settings.
  2. Select or create a key pair for SSH access (if applicable).
  3. Click "Launch instance".

Considerations After Launch:

  • The new instance will have a new instance ID and a new private IP address.
  • Update any configurations that depend on the specific instance ID, IP address, or hostname of the original instance.
  • If the original instance had an Elastic IP (EIP), you’ll need to associate a new Elastic IP to the cloned instance.
  • Check any software licenses tied to the instance, as they may need to be reconfigured for the new instance.
  • Ensure that you have the necessary IAM permissions to create AMIs and launch instances.

Additional Tips:

  • Automate with AWS CLI: You can automate this process using the AWS CLI commands (aws ec2 create-image and aws ec2 run-instances).
  • Instance Configuration Scripts: If you frequently clone instances, consider using user data scripts or AWS Systems Manager to automate post-launch configuration.
  • Cost Management: Remember that creating an AMI may incur storage costs, and running additional instances will increase your usage charges.

To Answer your question: now AWS make cloning real easy see Launch instance from your Existing Instance

  1. On the EC2 Instances page, select the instance you want to use
  2. Choose Actions --> Image and Templates, and then Launch More Like This.
  3. Review & Launch

This will take the existing instance as a Template for the new once.

or you can also take a snapshot of the existing volume and use the snapshot with the AMI (existing one) which you ping during your instance launch

You can use AWS API or console UI to create an AMI(Amazon Machine Image) of your running instance. You can specify to reboot the instance when create your AMI. Then you can use AWS API or console UI to launch more instances with the AMI you created.

You can make an AMI of an existing instance, and then launch other instances using that AMI.

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.

enter image description here

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:

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

The easier way is through the web management console:

  1. go to the instance
  2. select the instance and click on instance action
  3. create image

Once you have an image you can launch another cloned instance, data and all. :)

You can do it very easily with a Cloud Management software -like enStratus, RightScale or Scalr (disclaimer: I work there). With the cloned farm you can:

  1. Create a snapshot or a pre-made image to launch another day
  2. Duplicate your configuration to test it before production
