Where can users find examples of AWS Cloud solution designs?

Explanations:

The AWS Marketplace is primarily a platform for purchasing and deploying third-party software and services that run on AWS. It does not specifically focus on providing solution design examples.

AWS Service Catalog allows organizations to create and manage catalogs of IT services that are approved for use on AWS, but it does not offer a repository of solution design examples.

The AWS Architecture Center provides a wealth of resources including architecture best practices, reference architectures, and example designs to help users build secure, high-performing, resilient, and efficient infrastructure for applications.

AWS Trusted Advisor offers real-time guidance to help users provision their resources following AWS best practices but does not provide examples of solution designs.
