What is an AMI in AWS?
AMI stands for Amazon Machine Image. It is a pre-configured template that contains all the necessary software and settings to run a specific type of application on Amazon Web Services (AWS).
An AMI can be thought of as a "virtual machine" that you can launch in AWS, but instead of being tied to a specific physical server, it's a flexible, scalable, and portable image that can be launched across multiple servers.
AMIs are created by AWS or by users like you, and they come in different versions (e.g., "current" vs. "previous") to accommodate different use cases and requirements.
Some common examples of AMIs include:
* Linux AMIs for running web applications, databases, and other software on Linux
* Windows AMIs for running Windows-based applications and services
* Specialized AMIs for specific use cases, such as gaming, high-performance computing, or big data analytics
Once you have an AMI, you can launch it in AWS using the Amazon Elastic Compute Cloud (EC2) service, which provides scalable computing resources that can be quickly provisioned and terminated as needed.
