Subscribe to the Koha AMI on the AWS Marketplace using this link. You will be prompted to create a free account if you do not already have one.

Once the subscription is confirmed, click “Launch your software”. You will be redirected to a guided wizard that will walk you through the rest of the setup.

Under “Configure this software”, click “Fulfilment option” and select “CloudFormation template” (recommended).  Choose the software version and region. The default settings should be appropriate for most users.

Click “Continue to launch”

Review the launch configuration details and click “Launch”

A new tab will open in the console under CloudFormation > Stacks.

Under “Create stack” leave the settings at their default values. All URL to the CloudFormation template will already be filled out. Click “Next”.

Under “Specify stack details”:

• Stack Name:
  Enter a name like Koha-Library-Instance for easy reference.
• Instance Type:
  Choose t2.micro or t3.micro for AWS Free Tier. Use a larger type like t3.medium if needed.
• EnableSSH:
  Leave set to true to allow SSH access.
• SSHAccessCIDR:
  Default is 10.0.0.0/16. For better security, use your IP address (e.g., 203.0.113.25/32). You can find it at whatsmyip.org.
• Network Configuration:
  Leave VpcId and SubnetId blank to create a new network. If using your own, update SSHAccessCIDR to match your VPC.

You can re-run the stack later to update these settings if needed.

Under “Configure stack options”, leave there settings at their default values. Accept the acknowledgement under “Capabilities” and click “Next”

Review your configuration and click “submit”
