AWS and third-party vendors often provide public AMIs to streamline the process of deploying instances. These images can embody a range of software, from fundamental operating systems like Ubuntu, Red Hat, and Windows Server to more complex stacks that include pre-put in applications similar to web servers, databases, and development environments.
When to Use Public AMIs
Public AMIs are ideal for customers who want a quick and commonplace setup. As an example, if you need a fundamental Linux server or an ordinary Windows environment, a public AMI is an effective choice. Public AMIs are also helpful for many who need to test new software or configurations without the need to create a customized image. Nevertheless, it’s best to exercise caution when utilizing AMIs provided by third parties, making certain they arrive from trusted sources to keep away from security risks.

These AMIs are accessible to all AWS users and can range from easy operating system images to more specialised configurations. Community AMIs generally is a valuable resource if you’re looking for a setup tailored to specific use cases, equivalent to AMIs configured for particular development frameworks or area of interest applications.
When to Use Community AMIs
Community AMIs are helpful for those who’re looking for a highly particular environment or application setup that might not be available through public AMIs. For example, if you want an AMI configured with a particular version of a database, or for those who’re working on a project that requires a particular software stack, community AMIs can save you the time and effort of setting it up yourself. Nonetheless, as with public AMIs, it’s crucial to confirm the credibility of the source to avoid potential security vulnerabilities.
3. AWS Marketplace AMIs
AWS Marketplace AMIs are available through the AWS Marketplace, where vendors supply paid AMIs that come with additional support, features, and licensing. These AMIs are typically used for commercial software or enterprise-level applications, offering the advantage of being maintained and up to date by the software vendor.
