What are Images?
An Amazon Machine Image (AMI) is the basic unit of deployment in Amazon EC2 and is one of the types of images you can create with Image Builder. An AMI is a pre-configured virtual machine image that contains the operating system (OS) and preinstalled software to deploy EC2 instances.
AMI
An Amazon Machine Image (AMI) is a master image for the creation of virtual servers -- known as EC2 instances -- in the Amazon Web Services (AWS) environment. The machine images are like templates that are configured with an operating system and other software that determine the user's operating environment.
Why do we need AMI?
An AMI stands for Amazon Machine Images. An AMI is a virtual image used to create a virtual machine within an EC2 instance. You can also create multiple instances using a single AMI when you need instances with the same configuration.
