How Do I Create an AMI Using an Existing Web Server Instance?


Heather Bennett

Creating an AMI (Amazon Machine Image) using an existing web server instance is a useful and efficient way to replicate your server’s configuration and launch new instances with the same setup. This tutorial will guide you through the steps required to create an AMI from your existing web server instance.

Step 1: Accessing the EC2 Console

To begin, log in to your AWS account and navigate to the EC2 console. Here, you will find a list of your instances.

Step 2: Selecting the Web Server Instance

Locate the web server instance that you want to use as a base for creating an AMI. Click on the checkbox next to it to select it.

Step 3: Initiating the Create Image Process

With your web server instance selected, click on the “Actions” dropdown menu at the top of the page. From there, choose “Create Image”.


Before proceeding, ensure that your web server instance is in a running state and that there are no critical ongoing operations being performed on it. Creating an AMI involves temporarily stopping your instance.

Step 4: Configuring Your AMI

A dialog box will appear, allowing you to configure your new AMI:

  • Name: Provide a descriptive name for your AMI so that it’s easily identifiable later on.
  • Description: Optionally, add a brief description to provide more context about this specific AMI.
  • No Reboot: By default, AWS will attempt to stop and start your instance to create the AMI. However, if you select this option, it will avoid stopping your instance during the process (this may lead to inconsistent data).

Once you’ve filled in the necessary details, click on “Create Image” to initiate the creation process.

Step 5: Monitoring the Progress

After creating the AMI, you’ll be redirected to the AMI console, where you can monitor the progress of your image creation. The status will initially be “pending” and will change to “available” once completed.


The time required for creating an AMI can vary depending on the size of your instance and its associated storage. Larger instances may take longer to complete.

Step 6: Launching Instances from Your AMI

Now that your new AMI is available, you can use it as a template to launch new instances:

  • Navigate back to the EC2 console and click on “Launch Instance”.
  • Select the appropriate Amazon Machine Image (AMI) tab.
  • In this tab, you should find your newly created AMI listed. Select it by clicking on it.
  • Configure other settings for your new instance as needed (e.g., Instance Type, Security Groups).
  • Create and launch your new instance by following the remaining steps in the EC2 console.

Congratulations! You have successfully created an AMI using an existing web server instance and launched new instances based on it. This allows you to quickly scale your infrastructure or replicate your server configuration across multiple instances.

Remember to stay organized and keep track of your AMIs by providing meaningful names and descriptions to ensure easy identification in the future.

Now that you have learned how to create an AMI using an existing web server instance, you can leverage this knowledge to streamline your deployment process and improve the efficiency of your infrastructure.
