An AWS AMI is a machine image that contains all the necessary information to launch and run a virtual machine (VM) on Amazon Web Services (AWS). An AMI can be used to launch a new instance (a copy of a VM) on AWS. AWS provides a wide variety of pre-built AMIs that you can use to launch instances, or you can create your own custom AMI. You can also share AMIs with other AWS accounts.

Creating an AMI

AWS provides a variety of ways to create an AMI. You can use the AWS tools, take snapshots, or use third-party tools such as Terraform or Puppet.
You can create a custom AMI from an existing instance or from a snapshot of an instance.
You can use Terraform to create an AMI. Terraform is a tool that allows you to define infrastructure as code. This means that you can define your infrastructure in a file and then create it using the Terraform tool.
Puppet is another tool that can be used to create an AMI. Puppet allows you to define your infrastructure in code and then manage it using the Puppet tool.

Using an AMI

To launch an instance from an AMI, you must first select an AMI and then specify the instance type, network, and subnet that you want to launch the instance into. You can also specify additional settings, such as the instance name, IAM role, and security groups. Here is an example CLI command


aws ec2 run-instances –image-id <ami-id> –count 1 –instance-type t2.micro –key-name MyKeyPair –security-group-ids <dg-id> –subnet-id <subnet-id-id> –associate-public-ip-address –tag-specifications 'ResourceType=instance,Tags=[{Key=Name,Value=MyFirstInstance}]'

Pricing

There is no cost to creating an AMI. AWS charges for AMIs in three ways: storage, per-AMI, and data transfer.

  • Storage: You are charged for the storage consumed by the AMI and any snapshots associated with it.
  • Per-AMI: You are charged a one-time fee for each AMI you launch.
  • Data Transfer: You are charged for data transfer OUT from an AMI to the internet. Data transfer IN to an AMI from the internet is free.

Pricing for AWS AMI can be found on the AWS website.

Best practices for creating an AMI

If you're looking to create an AWS AMI (Amazon Machine Image), there are a few best practices to follow in order to ensure that your image is created correctly and efficiently. Below are some tips to help you get started:

  • Plan out your AMI ahead of time. What operating system and software do you need? What kind of instance will you be using?
  • Keep your AMI as small as possible. The smaller the image, the faster it will launch and the less storage it will use.
  • Make sure your AMI is well organized. This will help you and others who use it easily find what they need.
  • Test your AMI before you launch it. This will help you catch any potential errors and ensure that everything is working as it should.
  • Keep your AMI updated. As new software and operating system updates become available, make sure to apply them to your AMI so that users always have the latest version.

AWS AMI Marketplace

The AWS AMI Marketplace is a great place to find pre-configured Amazon Machine Images (AMIs) that can be used to launch Amazon Elastic Compute Cloud (EC2) instances. AMIs in the Marketplace come from a variety of sources, including Amazon Web Services, third-party publishers, and independent software vendors (ISVs).

There are a few things to keep in mind when using the AWS AMI Marketplace. First, you will need to have an AWS account and be logged in to the AWS Management Console. Second, you will need to have an Amazon EC2 instance running in order to launch an AMI from the Marketplace. Lastly, you will need to select the region in which you want to launch your instance.

Once you have an AWS account and are logged in to the AWS Management Console, you can browse the AWS AMI Marketplace. To find an AMI, you can use the search function or browse by category. Once you have found an AMI that you want to launch, you can select the "Launch" button.

On the next screen, you will be asked to select the instance type, region, and other options for your instance. Be sure to select the region that corresponds to the region in which the AMI is located. Once you have made your selections, you can launch your instance.

Conclusion

An AWS AMI is a machine image that contains all the necessary information to launch and run a virtual machine (VM) on Amazon Web Services (AWS). You can use an AMI to launch a new instance (a copy of a VM) on AWS. You can create a custom AMI from an existing instance or from a snapshot of an instance. To share an AMI with other AWS accounts or with the public, you can use the AWS Management Console, the AWS CLI, or the AmazonEC2 API.
