AWS and third-party vendors typically provide public AMIs to streamline the process of deploying instances. These images can include a range of software, from primary working systems like Ubuntu, Red Hat, and Windows Server to more advanced stacks that embrace pre-put in applications comparable to web servers, databases, and development environments.

When to Use Public AMIs

Public AMIs are ideal for customers who need a quick and customary setup. For instance, if you want a primary Linux server or a standard Windows environment, a public AMI is a good choice. Public AMIs are also useful for those who want to test new software or configurations without the need to create a custom image. However, it’s best to exercise caution when utilizing AMIs provided by third parties, making certain they come from trusted sources to keep away from security risks.
