AWS and third-party vendors usually provide public AMIs to streamline the process of deploying instances. These images can embody a range of software, from primary working systems like Ubuntu, Red Hat, and Windows Server to more complicated stacks that include pre-installed applications resembling web servers, databases, and development environments.
When to Use Public AMIs
Public AMIs are perfect for users who need a quick and standard setup. As an illustration, if you happen to need a fundamental Linux server or a normal Windows environment, a public AMI is an efficient choice. Public AMIs are additionally beneficial for many who wish to test new software or configurations without the necessity to create a customized image.
