Difference between AWS Partner Network & AWS Builder ID Sign-In

I apologize, but I don't have enough accurate information from the provided sources to fully answer your question about the difference between AWS Partner Network and AWS Builder ID sign-in, or their content differences. The sources don't contain specific information about the AWS Partner Network.

However, I can provide some information about AWS Builder ID based on the available sources:

AWS Builder ID is a personal profile that allows individuals to access certain AWS tools and services without requiring an AWS account. It represents you as a person and is separate from any AWS account or sign-in credential you may have. AWS Builder ID is designed to complement existing AWS accounts and allows access to specific services like Amazon CodeCatalyst, Amazon Q Developer, and AWS Training and Certification.

AWS Builder ID is managed by the individual who owns the identity and is not connected to any organizational identity. It stays with the person as they progress through personal, educational, and career goals.

The sign-in process for AWS Builder ID is specific to the service or tool you want to access. For example, to use Amazon CodeCatalyst, you would go to its specific login page.

Without more information about the AWS Partner Network sign-in, I cannot provide a comparison or discuss content differences between the two. If you have more specific questions about AWS Builder ID, I'd be happy to try to answer those based on the information available.
