AWS and third-party vendors often provide public AMIs to streamline the process of deploying instances. These images can embrace a range of software, from fundamental working systems like Ubuntu, Red Hat, and Windows Server to more complex stacks that embrace 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 normal setup. As an illustration, if you want a fundamental Linux server or a standard Windows environment, a public AMI is an effective choice. Public AMIs are also beneficial for those who wish to test new software or configurations without the need to create a customized image. Nevertheless, you should exercise warning when utilizing AMIs provided by third parties, making certain they come from trusted sources to keep away from security risks.

Community AMIs are useful in the event you’re looking for a highly particular environment or application setup that may not be available through public AMIs. For example, in the event you need an AMI configured with a specific model of a database, or when you’re working on a project that requires a particular software stack, community AMIs can save you the effort and time of setting it up yourself. Nonetheless, as with public AMIs, it’s essential to verify the credibility of the source to avoid potential security vulnerabilities.
3. AWS Marketplace AMIs
AWS Marketplace AMIs are available through the AWS Marketplace, the place vendors offer paid AMIs that come with additional support, options, and licensing. These AMIs are typically used for commercial software or enterprise-level applications, providing the advantage of being maintained and updated by the software vendor.
