In this article, I’m going to discuss What is AMI in AWS and how to create AMI from EC2 Instance? If you want to know the entire process of creating AMI from EC2 Instance, this article is going to be very helpful for you.
Before Starting the Whole Process, I would love to share some details about AMI in AWS because many people don’t know about it.
What is AMI in AWS?
AMI in AWS stands for Amazon Machine Image. AMI’s are templates that contain all the information needed to launch an instance, including the operating system, application server, and applications. AMI’s are used to launch instances, which are virtual machines that run on Amazon EC2. AWS provides a variety of AMI’s, and you can also create your own AMI’s. When you launch an instance from an AMI, you specify the AMI that you want to use, as well as the instance type, which determines the size and performance of the instance.
You can also specify additional options, such as the security groups and key pairs that you want to use. After you launch an instance, you can connect to it and use it just like any other computer. You can install software, run applications, and store data on the instance. When you no longer need an instance, you can terminate it to stop paying for it.
An Amazon Machine Image (AMI) provides the information required to launch an instance.
This includes the operating system and other software required to run the instance. When you launch an instance, you specify an AMI, which determines the operating system, application server, and applications that are installed on the instance. You can also specify additional options such as the instance type, security groups, and key pairs. After you launch an instance, you can connect to it and use it just like any other computer. You can install software, run applications, and store data on the instance. When you no longer need an instance, you can terminate it to stop paying for it.
AWS provides a variety of AMIs, and you can also create your own AMIs. To create an AMI from an EC2 Instance, you should follow these Instructions.
